The waters off the coast of Indonesia were rattled by a 5.2 magnitude (M) earthquake, according to the United States Geological Survey (USGS). It occurred 72 km west of Tiku, and 95 km west of Sumatra, at 7:54:33 UTC, Sunday, Jan. 17, 2016. One person has reported feeling the Tiku rumblings in Padang, Indonesia, which is 131 km Northwest of the impact site.
On the same day, there was a reported total of 96 instances of seismic activity, ranging from 1.5 M and higher, recorded worldwide. Five of them happened in the surrounding area. The Timor region reported a 4.6M at 23:59, with a depth of 54.7 km at its epicenter. Southern Sumatra reported two more earthquakes at 18:54, both with a 4.9M and depths of 68 and 64 km, respectively. Timor also reported two additional earthquakes at 4:35, at 4.9M and 5.1M, with depths of 30 and 21 km.
The 5.2M shaker that rattled the coastline is on a collision zone which is prone to seismic activity. The collision zone contains the Sunda-Java trench, which accommodates the convergence between the Indo-Australia and Sunda plates. The trench stretches 8,000 km from Papua, New Guinea, to the Himalayan Front in the west. The USGS says this convergence is responsible for the fearsome earthquakes and rampant volcanism in Sumatra.
Sumatra was the site of 2004’s terrifying earthquake, which was the deadliest in history. There was a recorded 9.1M that resulted in a tsunami that was subsequently the most dangerous and deadliest in history.
Although today’s tremors happened underwater, there has been no tsunami warning declared yet.
