In Indonesia, the earthquake often occured. Because the location of Indonesia is in Eurasian plate. And it between the Australian plate and Philippine plate. For example on September 2009, Sumatra earthquake occurred just off the southern coast of Sumatra, Indonesia. The major shock hit at 17:16:10 local time on September 30, 2009 (10:16:10 UTC) and had a moment magnitude of 7,6. The epicenter was 45 km (28 mi) west-northwest of Padang, Sumatra, and 220 km (140 mi) southwest of Pekanbaru, Sumatra.

Earthquake occurred, because the location is situated within a zone of high seismic activity known as the "Pacific Ring of Fire". Along the Sunda megathrust, the Indo-Australian Plate is being subducted beneath the Eurasian plate. The subduction creates regular earthquakes, many of them of megathrust type. Specifically the Sumatran segment is currently experiencing a period of increased activity that began with the catastrophic 2004 Indian Ocean Earthquake. Each earthquake of the sequence adds additional stresses to segments of the plate boundary that have not moved recently.

Because of its depth and the computed focal mechanism, the first earthquake is thought to have resulted from deformation within the descending Indo-Australian plate, rather than from movement on the plate boundary itself. The second earthquake has been linked to dextral (right-lateral) movement on the Great Sumatran fault which takes up the strike-slip component of the convergence between the two plates.

This disaster cause some effect. After this disaster occurred, tsunami watch was triggered and there are reports of house damage and fires. The communications to the city were disrupted. It make many people and child who still alive in there feel difficult to survival.

I will show you the video of Padang Earthquake.. You must see it!!!
