Earthquake Sora, Southern Italy (Lazio – Frosinone) – 63 year old woman dies from a hearth attack

Last update: February 17, 2013 at 10:20 am by By

Update Febr. 17 – 09:18 UTC : A 63 year old woman in Isola Liri has died from a heart attack due to this earthquake. ER sends his condolences to her family. Er sees hearth attacks as secondary deaths as the damage of the earthquake cannot be held responsible as the cause.

Villages and towns within 10 km from the epicenter : ARPINO (FR), BROCCOSTELLA (FR), CASTELLIRI (FR), ISOLA DEL LIRI (FR), MONTE SAN GIOVANNI CAMPANO (FR), PESCOSOLIDO (FR), SORA (FR) and BALSORANO (AQ)
Villages and towns within 10 and 20 km from the epicenter :  ALVITO (FR), ARCE (FR), BOVILLE ERNICA (FR), CAMPOLI , PPENNINO (FR), CASALATTICO (FR), CASALVIERI (FR), CEPRANO (FR), COLFELICE (FR), FONTANA LIRI (FR), FONTECHIARI (FR), POSTA FIBRENO (FR), RIPI (FR), ROCCA D’ARCE (FR), ROCCASECCA (FR), SANTOPADRE (FR), STRANGOLAGALLI (FR), TORRICE (FR), VEROLI (FR), VICALVI (FR), COLLELONGO (AQ), MORINO (AQ), SAN VINCENZO VALLE ROVETO (AQ) and
VILLAVALLELONGA (AQ)

Italian tectonics are very complex and are mainly complicated subduction processes (subduction is also responsible for the Italian volcanoes). A very good scientific but easy to understand article can be found here.

Update 23:40 UTC : Luckily NO reports of serious damage, but the people in the greater epicenter area are really frightened. Some villages and towns have setup temporary shelters to allow people who are too frightened to sleep there. Others prefer to sleep in their cars.

Update 22:13 UTC : There have not been any reports of major damage as yet and only panic and minor non-structural damage has been seen as yet.

Update 22:00 UTC : This earthquake also caused similar concern from residents of Rome to that of 2009, with calls to emergency services despite no damage.

Update 21:58 UTC : The earthquake was even felt in l’Aquila. Our second map (at the bottom) shows that there were NO other earthquakes in this area since the beginning of 2012.
This earthquake is around the same place as the 1980 Irpinia earthquake causing major damage. This earthquake will normally  only cause minor damage if any presumably.
In 1922 a M5.6 earthquake struck the Sora area and caused some damage too.

Update 21:51 UTC : A  good sign is an experience report from a reader who said that the motion he felt was mostly vertical and not horizontal. Horizontal accelerations are the most damaging. A second good sign is that other readers tell us that the shaking lasted only a couple of seconds, long lasting shaking increases the chance on damage.

Update 21:48 UTC : A lot of people ran on the streets as they were frightened not only from the earthquake but also from the aftershocks

Update 21:40 UTC : The website from INGV Italy, the National Seismological agency is hard to enter because of the many people looking at them.
Region : Lazio (population 5,196,447) . The nearest places are Latina, Sora, Isola del Liri, Broccostella, Carnello, Cisterna, Vallefredda, and San Domenico. The maximum altitude nearby is 2689m .

Update 21:35 UTC : Our biggest concern are the old buildings in Sora. From Emilia Romagna, we know that these are very vulnerable for even moderate shaking. This earthquake can however NOT be compared with that earthquake as the intensity is a lot less.

Update 21:35 UTC : GDACS reports that at least 100,000 people are living within a radius of 10 km from the epicenter

Update 21:33 UTC : INGV Italia is reporting a Magnitude of 4.8 at a depth of 10.7 km

Update 21:32 UTC : Based on the current data, ER does not expect any serious damage from this earthquake

Update 21:31 UTC : the earthquake will certainly have been felt in Rome, as Rome is only at a distance of 90 km from the epicenter

Update 21:29 UTC : EMSC reports a Magnitude of 4.8 at a depth of 12 km.
Sora, very near the epicenter is a city with a population of 26,600 people

The preliminary Magnitude as reported by Geofon was M4.6
