Massive earthquake close to Champerico, Guatemala
Last update: November 7, 2012 at 5:23 pm by By Ashish Khanal
Update 17:34 UTC : The Guatemalan Instituto Nacional de Sismología reports a Magnitude of 7.2 at a depth and mentions a MMI of V at many Guatemalan locations. The earthquake was well felt at Guatemala, Jalapa, Jutiapa, Alta Verapaz, Quetzaltenango, Suchitepéquez, Zacapa, Escuintla and Quiché.
Update 17:26 UTC : Based on the current USGS data, 236000 people will have experienced a very strong shaking (MMI VII). Nearly 2 million people a strong shaking. We will have to wait a little longer to get a better view on the potential damage. The chance on damage cannot be excluded as the location of the epicenter has been relocated closer to the coast.
Update 17:23 UTC : The max. MMI has been increased by USGS from VI to VII (strong increased to very strong shaking). The main risk however is a tsunami risk at the closest shores to the epicenter.
USGS is currently reporting a Magnitude of 7.5 at a depth of 33 km.
Luckily the epicenter is about 20 miles out of the coast which will weaken the shaking a lot.
So far a MMI VI has been reported (strong shaking).
There will certainly have been called a Tsunami alarm as the epicenter was close to the coast.
NOAA stipulates that there is NO tsunami warning for ALASKA/ BRITISH COLUMBIA/ WASHINGTON/ OREGON AND CALIFORNIA…, which must be a relief for those areas.

We will soon start an in-depth article on this massive earthquake.
Update 17:09 UTC : The max. shaking values we have received so far are MMI VI, which is very hopeful (minor damage and injuries expected at these values). The first reports we did receive did locate the epicenter closer to the coast, which is not confirmed by other agencies.
