Major 7.9 Magnitude Quake Strikes Southwest of Indonesia
TEHRAN (Tasnim) – A powerful and shallow earthquake of magnitude 7.9 struck off the west coast of the Indonesian island of Sumatra Wednesday, the US Geological Survey said.
The country has issued a tsunami warning, Russia Today reported citing the National Meteorolgical Agency.
The shallow quake, which hit southwest of the island of Sumatra on Wednesday, had a depth of 10 kilometers (six miles).
The epicenter was located 808 kilometers (502 miles) southwest of Padang.
There were no immediate reports of damage or casualties. However, shallower earthquakes are more likely to cause damage.
The USGS originally categorized the quake as a magnitude 8.2, and later an 8.1, before lowering it to a 7.9.
In 2004, a 9.1 magnitude earthquake struck 160 kilometers (99 miles) off the western coast of northern Sumatra, resulting in a tsunami.
Indonesia straddles the so-called 'Pacific Ring of Fire,' a highly seismically active zone where neighboring tectonic plates violently clash, resulting in a large number of earthquakes and volcanoes.
