7.3 magnitude earthquake strikes off the west coast of northern Sumatra

January 10, 2012INDONESIAA 7.3magnitude tectonic earthquake at a depth of 29 km (18 miles) was recorded on Tuesday, 420 km (260 miles) south west of Banda Aceh, Indonesia, the U.S. Geological Survey said. No immediate tsunami warning was issued by the Pacific Tsunami Warning Center for its Indian Ocean area but later that was changed. The epicenter of the strong earthquake was about 1789 km (1111 miles) WNW of Jakarta, Java, Indonesia. The earthquake lasted for about 30 seconds, and residents in the provincial capital, Banda Aceh, rushed out of their homes in fear, an AFP reporter said. They later returned indoors. In recent weeks, a spasm of earthquakes have rattled the region in around Indonesia and currently 7 volcanoes in the very geologically-active archipelago are on high alert status. The earthquake is the second large earthquake of 2012 and comes on the heels of yesterday’s 6.6 magnitude earthquake which struck the Santa Cruz Islands. –The Extinction Protocol

    Update : Indonesian media are currently reporting a SR magnitude of 7.6
    A 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

    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

    Important Update for the Pacific countries :
    NOAA also indicates that : A DESTRUCTIVE WIDESPREAD TSUNAMI THREAT DOES NOT EXIST BASED ON HISTORICAL EARTHQUAKE AND TSUNAMI DATA. Click here for there entire report
    NOAA has the same green alert for the Indian Ocean
    Indonesia, as closest island to the epicenter has to looked at separately

    Update : We have currently some problems in updating because of too many people reading our webpages. Sorry about that.

    Tsunami wave animation – The wavbes are calculated by GDACS to be max. 1 meter when arriving al land areas

    Update : As we cannot reach the website of BMKG, we do not know whether a tsunami alarm has been called in Indonesia Sumatra and the Sumatra islands, but bearing in mind what happened in the past and knowing that the Indonesian authorities are fast in calling a tsunami alert, it can be expected.
