Unknown Fault Responsible for Utah Quake 3/24/20

After a 5.7 earthquake, Utah seismologists investigate a ‘virtually unknown’ fault

Soon after Salt Lake City stopped shaking March 18 from its strongest earthquake on record, Amir Allam, a University of Utah seismologist, knew he had to get busy if he hoped to closely study the hundreds of aftershocks he knew would follow the 7:09 a.m. jolt.

The fault that is believed to have moved along the eastern base of the Oquirrh Mountains is virtually unknown, and here was a chance, dropping out of the blue, to image it.

But Allam had a problem.

All 210 of the U.’s portable seismographs, loaf-sized instruments known as nodal geophones, were currently deployed along California’s San Andreas fault and elsewhere, and, therefore, were unavailable for what he needed to do in his own backyard. The Salt Lake Valley hadn’t had a sizable shake since 1962 and last week’s 5.7 magnitude earthquake offered a rare opportunity to better map the network of fractures under the valley.

Allam and his U. colleagues quickly mustered up dozens of geophones from other institutions and began burying them near the epicenter of the initial quake, likely on a fault that has remained a mystery to Utah seismologists.

They hope to characterize it and determine how it is interconnected with the Wasatch fault running along the base of the foothills on Salt Lake City’s east side and its lattice of associated faults, or “strands.”

‘Jury is still out’

“We started immediately the morning of the [initial] earthquake, and we have been installing them ever since,” Allam said Tuesday as he unloaded shovels and 43 geophones from his truck. “These are the last bunch.”

He already had deployed 139 geophones, each equipped with 35 days of battery life, around the Salt Lake Valley, each measuring ground movements — vertical, north-south and east-west — from hundreds of aftershocks. These recordings will help scientists with the U., as well as the Utah and U.S. geological surveys, to characterize this intriguing fault.

The Wasatch fault system’s network of cracks in the earth stretches 230 miles from Malad, Idaho south to Fayette, Utah through Utah’s major metropolitan area, where at least 80% of the population resides. A magnitude 6 quake on the main fault could cause severe damage, depending on where it strikes. A 2016 report forecast a 57% chance of such a quake or stronger within the next 50 years. Scientists do not believe last week’s temblor will reduce the chance of a major quake on the Wasatch fault down the road.

“We want to map out the basin depth all over the valley. We actually don’t know it [the fault network] that well,” Allam said. “… We want to capture as many tiny aftershocks as we can, so we have a really dense deployment around the epicenter of the 5.7 quake. We want to get that fault structure. We want to know exactly how the Wasatch and its subsidiary faults are changing their patterns in the subsurface.”

The fault that likely moved dips to the west and is not expressed on the surface, according to Kris Pankow of the U. Seismograph Stations. It could be the same one that shook Magna in 1962 with a magnitude 5.2 quake that touched off a swarm of lesser aftershocks, but it can’t be known for sure because the instrumentation was not in place to precisely locate that quake.

“The jury is still out on the specific fault that moved and produced [the March 18] earthquake,” said Ryan Gold, a research geologist with the U.S. Geological Survey. “The specific strand, that’s what we are trying to sort out. Additional instrumentation is being installed to monitor ongoing seismicity.”

‘Aftershocks are going to diminish’

(Francisco Kjolseth | The Salt Lake Tribune) University of Utah seismologist Amir Allam deploys 43 portable seismic instruments to be buried above Salt Lake City on Tuesday, March 24, 2020, to capture data following last week’s 5.7 magnitude earthquake.

In the week since the main quake, the ground under Magna has kept shaking.

As of Tuesday at 4 p.m., 456 aftershocks had been recorded, according to Gold, coming at an average rate of one every 20 minutes. At least 29 were magnitude 3 and a handful exceeded magnitude 4. The fault released a magnitude 3.1 temblor Tuesday at 5:32 a.m., followed by many stronger than magnitude 2. Most were located very close to the original epicenter a few miles north northeast of Magna and just six miles beneath the surface.

“The number and size of aftershocks are going to diminish with time but within these sequences. It’s the fault adjusting to the changes in stress. They are kind of chattering,” said Pankow, who is also closely monitoring aftershocks with larger seismographs placed in a few strategic locations. “With time, that stress is going to dissipate.”

The larger instruments are connected to broadband, providing real time data on the aftershocks. Meanwhile, satellite imagery shows the ground moved several centimeters at the surface as a result of the main quake, according to Gold.

The aftershocks don’t occur in steady intervals but in clusters, according to a graphic representation posted by Seismograph Stations. In the first three days after the mainshock, dozens of aftershocks flared. They grew weaker and less frequent until Sunday night, when a magnitude 4 struck, followed quickly by numerous aftershocks.

“That magnitude 4 was its own stress release; it has its own set of aftershocks to go with it,” Pankow said. “We might have some more magnitude 4s before this is all done.”

Seismometers, types of seismograph that measure surface ground movement, are installed in at least three major historic structures in downtown Salt Lake City: the Utah Capitol, City Hall and West High School. These instruments record direction, intensity and duration of earthquakes. The data generated by these instruments helps engineers understand the seismic forces buildings on the Wasatch fault system could be subject to, according to Pankow.

Hillside research

An assistant research professor in the U.’s Department of Geology and Geophysics, Allam teaches jiu jitsu on the side. On Tuesday, he recruited some of his students on a moment’s notice to help schlep instruments into the hills above Salt Lake City’s Avenues neighborhood as the weather deteriorated in front of a snowstorm expected to arrive by Wednesday.

They hoisted 50-pound satchels over their shoulders, each holding six geophones, and trekked a half-mile up the Bonneville Shoreline Trail to a spot where Allam had identified a 500-meter transect along a ravine that was just starting to green up with the coming of spring. Here the team was to plant the geophones along a preselected line spanning a known strand of the Wasatch fault in the undulating terrain overlooking the city.

As a cold rain began to fall, the crews dug 8-inch holes in 13-meter intervals along a downsloping ridgeline on a roughly north-south axis. The geophones were placed in the holes, oriented directly north, and covered with dirt.

In a month, Allam and his associates will return to recover 182 geophones around the valley. The harvest is hoped to yield a bounty of data that paints a valuable picture of what lurks beneath Utah’s most populated region.

Massive earthquake and Tsunami Santa Cruz Islands (Solomon Islands) – 13 people killed, many missing + horrifying aftershocks

Last update: February 8, 2013 at 5:25 pm by By

Most important Earthquake Data:

Magnitude : 6.1

Local Time (conversion only below land) : 2013-02-06 11:07:25

GMT/UTC Time : 2013-02-06 00:07:25

Depth (Hypocenter)  : 10 km


Since the devastating Tsunami in 2004, people take no risk and move to higher ground, some even auto-evacuating. Honaria, the capital of the Solomon Islands, far outside the shaking area, people are currently moving to higher ground.

Update 03:24 UTC : The Pacific Tsunami Warning Centre has corrected its recent update. Australia is NOT in the warning area.
04:23 but is still on watch

During a Tsunami the first wave is not always the biggest one – stay on high ground until the authorities are calling the alert off

Update 03:12 UTC :The Solomon Islands Broadcasting Corporation cited a witness who said water was covering an airstrip in Lata

Update 03:11 UTC : The Solomon Islands Visitor Centre has spoken to ABC News 24, confirming the 90cm sea level rise in the Santa Cruz Islands.  In Lata, the provincial capital of the worst-hit area, there are no reports of damage so far.

Update 03:05 UTC : A New bulletin from PWTC has just arrived. We bring it to you in a minute
– Evacuations are being ordered by many, many Pacific countries. Authorities are taking NO risk and are evacuating even islands and coastal areas which are not on the dangerous NOAA list !
ISSUED AT 0252Z 06 FEB 2013






Update 02:57 UTC : AustraliaNetworkNews / @an_news, a very well informed news agency reports vuia Twitter that : Emergency authorities on Santa Cruz island have confirmed the tsunami has destroyed three villages on the island @ABCNews24

Update 02:57 UTC : Map 2 below is showing 3 very big balloons. These are the same earthquake of course, but they show the locations of the epicenter as reported by Geofon, USGS and EMSC. Epicenter calculation is extremely difficult. Our map shows it very good.

Update 02:51 UTC : A very interesting graph is from the Sea Level gauge at the Lata Wharf, relatively close to the epicenter. The gauge confirms the after all limited height of the tsunami. We have to say however that the currents with a tsunami of 1 meter can also be very powerful and even damage a lot of things.

Screen Shot 2013-02-06 at 03.45.16

Update 02:48 UTC : Robert Speta, one of the people collaborating with Earthquake-Report.com and meteorologist at NHK Japan made the following video. Of course this video was made shortly after the earthquake.

Update 02:44 UTC : ONE News has spoken to Charles Ngali who is in Lata Hospital in the Solomon Islands. He says he felt a series of strong earthquakes. The hospital is on high ground but he has heard that a wave passed through the airport, which is on lower ground. Most of the patients at Lata Hospital have been taken to higher ground.

Update 02:41 UTC : Tsunami travel time map as compiled by NOAA

Tsunami Travel Time Map M8.0 Santa Cruz Islands earthquake

Update 02:38 UTC : And like the M8.0 was not yet enough, the M6+ aftershocks are raging further.

Update 02:36 UTC : AFP reports that : “The information we are getting is that some villages west and south of Lata along the coast have been destroyed, although we cannot confirm this yet,” the director at Lata Hospital on the main Santa Cruz island of Ndende, told AFP.

Indonesia Earthquake 1/10

Massive earthquake out of the coast of Northern Sumatra, Indonesia – Tsunami alert lifted

Last update: January 11, 2012 at 8:22 am by By 

January 10, 2012 By 

Earthquake overview : A massive earthquake occurred several hundred km out of the Sumatra Banda Aceh coast. Theoretical calculations concluded that no widespread tsunami would occur in the Pacific Ocean. Indonesian authorities have however called a tsunami alert for many areas in Sumatra.

WISE TSUNAMI ADVICE in case you are living or traveling to an earthquake rich area of the world and are residing close to the coast :  EVACUATE IMMEDIATELY TO HIGHER GROUNDS (10 to 30 meters higher than sea level) IF :

– strong shaking goes on for 30 seconds or longer
– the authorities are calling for an evacuation
– you see a fast unusual retreating sea

Triggers of today’s massive earthquake :
The January 10, 2012 earthquake off the west coast of northern Sumatra, Indonesia, occurred as a result of strike-slip faulting within the oceanic lithosphere of the Indo-Australia plate, approximately 100 km to the southwest of the major subduction zone that defines the plate boundary between the Indo-Australia and Sunda plates offshore Sumatra. At the location of this earthquake, the Indo-Australia plate moves north-northeast with respect to the Sunda plate at a velocity of approximately 52 mm/yr.
While they are rare, large strike-slip earthquakes are not unprecedented in this region of the Indo-Australian plate. Since the massive M 9.1 earthquake that ruptured a 1300 km long segment of the Sumatran megathrust plate boundary in December of 2004, two Mw 6.2 strike-slip events have occurred within 50 km of the January 10 2012 event, on April 19 2006, and October 4 2007. These events seem to align with fabric of the sea floor in the diffuse boundary zone between the Indian and Australian plates. (summary as described by USGS)

Update : At midnight UTC,  4 aftershocks ranging from 4.8 to 4.9 have been listed by USGS.

Update : The tsunami alert was maintained longer at Simeulue  island (Aceh province) as this island was closest to the epicenter. Although Simeulue was not indicated as a place at risk by the GDACS simulation, authorities do not want to take any risk.

Important update : Indonesian authorities have lifted the earlier called Tsunami alert. People in Banda Aceh reported a retreating sea after the earthquake occurred, just like it happened in 2004 during the devastating tsunami who killed more than 200,000 people.  Luckily no reports about any serious waves so far.

Update : We know from earlier experiences in Indonesia that local people often do not trust the authoritiesand remain in safe locations even if the authorities ask them to return to their house and pick up their daily life. Additionally, rumors are often spread that an even heavier earthquake and tsunami will be triggered. Rumors are one of the major problems after earthquakes.

Update : Indonesian media are reporting that BMKG, the local Indonesian seismological agency, has lowered the magnitude from 7.6 to 7.1. BMKG triggered an early warning tsunami alert to the local agencies. BMKG received reports that people fled their houses almost automatically for a safe location. No reports as yet from the real wave heights. People have been asked to stay in the safe places for a longer time and not to return to heir houses to soon.

Update : A lot of panic amongst the Sumatra population when they felt the earthquake and when the tsunami sirens went off.

Red bullets are indicating Tsunami alert from the Indonesian authorities

Update : MetroTV Indonesia is one of the only channels reporting on the earthquake and potential tsunami risk. The image at right shows where the Indonesian authorities have called a tsunami alarm for the coastal areas.

Update : Based on the GDACS data, the time that the waves may have reached Simeulue and Northern Sumatra is over now.  We expect final experience reports soon.

Update : We still cannot reach BMKG, the Indonesian seismological agency via the Internet due to too heavy demand.  This happened also in the USA during the Virginia earthquake (USGS).

Update : If all theoretical data will be confirmed, this was a LUCKY ESCAPE, but this earthquake will have send vibrations of fear through the population of Northern Sumatra.

Update : The GDCAS image below shows very well the propagation of the tsunami wave from the epicenter versus the northern part of Sumatra, including Banda Aceh.  GDACS has calculated based on historical earthquakes and lots of additional data, that the waves in Northern Sumatra will be max. 0.4 meter

Tsunami wave distribution and height – Image courtesy GDACS

Update : Indonesian media are currently reporting a SR magnitude of 7.6
TSUNAMI ALERT has been called by the local BMKG for parts of the country (unclear at this moment, but certainly the islands and Sumatra, including Banda Aceh). Our experience is that people in Indonesia are mostly not waiting for an alert but are auto-evacuating when a strong shaking for more than 30 second occurs.
Indonesian media are only reporting earthquake numbers , no background information yet

Fault line west of the Sumatra coast

Update : Magnitudes and depths as calculated by other seismological agencies :
EMSC : M 7.3 @ 10 km
GEOFON (Germany) : M 7.1 @ 10 km
CEN (China) : M 7.2 @ 20 km

Christchurch, New Zealand Aftershocks

3 large dangerous aftershocks hit Christchurch, New Zealand – shaking video

Last update: December 24, 2011 at 12:51 pm by By 

Earthquake overview : Multiple aftershocks hit the city of Christchurch and his suburbs during the early afternoon of December 23. 2 major aftershocks measuring 5.8 and 5.9 magnitude were the largest since many months.

Video of the shaking of the M 6.0  earthquake

Michelle Collins from Christchurch captured the shaking by accident as her camcorder was still running while positioned on a Christmas tree. She talks to the NZ Herald about the experience. This is what a M 6.0 feels like if you live near the epicenter. The heavy shaking lasted “only”  10 seconds, longer would certainly have generated much more damage. Miss Collins runs immediately outside while the shaking is still going on. Not wise at all, but in her case forgivable as she was only a few meters away from the patio/garden.

Liquefaction also occurred today. Funny to look at but something which may become very dangerous with higher magnitudes

Update 18:55 UTC
CERA (Canterbury Earthquake Recovery Authority) has advised the authorities that a Christchurch wide survey of houses would be desirable. The main reason of such a check is to find out whether the houses can withstand a new strong earthquake.

Update 17:40 UTC
M 5.1      2011/12/23 17:36    Depth 9.0 km     CHRISTCHURCH, NEW ZEALAND

Satellite map of the greater epicenter area

Update 16:26 UTC
In Sydenham, the 100-year-old former Post Office building was demolished last night after sustaining further damage during yesterday’s aftershock.

Update 16:10 UTC
29 + M 3.0 aftershocks since the mainshock!

Update 15:06 UTC – An example to all earthquake sensitive countries in the world
Telecommunications were not hit that hard as a result of the quake. The disruption noticed was due to the problems with the main power supply, which implicated that some equipment was operating on battery and generator backup.
Telecom was asking people to use texts, rather than calling, in order to ease the load on its mobile networks. Emergency calling remained operational (Earthquake-Report.com is in favor of this policy – other countries should follow this example asap (we have encountered continuous problems elsewhere in the world due to too high peaks and due to non-battery backup masts).

Update 10:52 UTC
It looks like the current epicenter can be called “little out of range” of the other powerful earthquakes. The epicenter of the initial quake who triggered the other ones was was located a little out of the coast. Hopefully this will not start off a new episode of aftershocks

Oklahoma Quake Aftershocks

Oklahoma rattled by 5.6 earthquake

Homes damaged and roads buckled by series of shocks including the biggest on record in US state

Oklahoma has been shaken by a series of earthquakes

Earthquakes of up to 5.6 magnitude have shaken Oklahoma, damaging buildings and roads and sending a handful of people to hospital.

The first quake was recorded on Saturday morning at a magnitude of 4.7. The second came on Saturday night and is the largest recorded in Oklahoma, topping a tremor of 5.5 magnitude in 1952, according to the US Geological Survey.

In Prague, Oklahoma, where the first quake was centred, city manager Jim Greff said part of the town library’s ceiling collapsed and a chimney fell through the roof of a home. There were no serious injuries.

The quake buckled highway 62 in three places west of Prague and sent a boulder “about the size of an SUV” tumbling onto a rural road in south-east Lincoln County, said Aaron Bennett, dispatch supervisor for the county’s emergency management division.

The quake was felt more than 300 miles away in Kansas City, where it rattled windows and shook houses for half a minute.

The second quake was a shallow 3.1 miles (5 km) deep and centered four miles east of Sparks, east of Oklahoma City.

JL Gilbert, owner of the Sparks Vineyard and Winery, about four miles from the epicentre of the second quake, said it lasted “a good 30 seconds”.

“It was a pretty good jolt. We’re not used to this. We’re used to being sucked up into the wind,” he said, referring to Oklahoma’s reputation as a tornado alley.

Earthquakes of a 4.0 magnitude east of the Rocky Mountains can typically be felt from up to 60 miles away, according to the USGS. A 5.5 magnitude quake can be felt up to 300 miles from its epicentre.

One of Gilbert’s employees went to the hospital after tripping and hitting his head on a doorway while scrambling to get out of his home, Gilbert said.

Turkey —- Strong Earthquake

Very strong damaging earthquake in eastern Turkey – 200 prisoners escaped in Van

Last update: October 23, 2011 at 7:18 pm by By 

Image courtesy www.haberler.com – click on the picture for the photo gallery

Update: There have been 104 aftershocks over M2.7 so far. 22 aftershocks over M4. 4 aftershocks over M5.

Important Update 19:07 UTC87 deaths and 1000 injuries is the estimate at the moment. (Ercis = 60, Van = 25, other localities = 2). This is expected to rise substantially.

– Van Prison : 200 inmates escapedapparently grabbing the opportunity of earthquake.
– According to the news from Agencies, 38 provinces have send 1275 search and rescue personnel.
– Kandilli Observatory ELER says taking into account the number of buildings that become uninhabitable = 3200-3400, severely damaged buildings = 600 and completely collapsed buildings =  50; 500-700 deaths is the approximate estimate. News from rural locations has not been collected but damage is estimated at around 60-70 percent.

Update 18:58 UTC:  The Turkish government is sending skilled SAR  personnel (Search and rescue) from the other provinces to Van. The Van airport is till operational what facilitates transport to the earthquake zone. On top of that much equipment like ambulances, tents, medical personnel, etc. Turkey is well organized to deal with earthquakes.

Update 18:21 UTC:  – The weather outlook tonight is mixed. It is not raining or snowing but thetemperatures will be at freezing point. As people will prefer to stay in the open air (to scared to go inside for eventual very strong aftershocks), they may have a night with almost no sleep.
– As the night has fallen in Turkey (it is now 21:21 in Turkey) limited news facts are coming through.
– The death toll is unchanged since many hours at 85 but will certainly increase within the next 4 to 24 hours. A lot of people are still buried under the debris of the collapsed houses.
– We cannot reach the server from the local Ercis newspaper anymore
– NATO stands ready to assist Turkey  if needed

Update:  Doctors from Ercis State Hospital reported that the number of the injured patients is close to 1000. Many patients are kept in the hospital’s parking lot and the garden in tents.

Update:  The Armenian President sent an message of condolences to the President of the Republic of Turkey Abdullah Gül regarding the earthquake that occurred in the Van province. Armenia is located at a relatively short distance from the earthquake area and people in Armenia were very frightened by the shaking (see I have Felt It reports below).

UpdateGermany has offered help to Turkey after an earthquake hit the eastern province of Van
The German Green Party called on the international community to provide fast and “unbureaucratic” support for rescue workers.

New casualty Update:   85 people are now reportedly killed during this earthquake (25 in Van and 60 in Ercis)

Update:   – A lot of people are leaving the cities and are heading for family in the rural areas. They fear the narrow streets with medium rise apartment buildings.
– Israel has offered to help Turkey with this disaster. It is unknown that Turkey has accepted this offer, as the 2 countries had a lot of differences in the recent past. In a later message Turkey declined the offered aid in saying that Turkey will deal with it internally.

Aftershocks Hit Virginia

Strong aftershock below Cuckoo and approx. 8 km from Mineral, Virginia

Last update: August 25, 2011 at 6:59 am by By Armand Vervaeck and James Daniell

Earthquake overview : A moderate aftershock has rattled the Virginia earthquake area. We do not expect any additional damage, but based on the Felt reports, the earthquake was felt in a wide area
