A strong magnitude 6.0 earthquake occurred at 00:01:16 (UTC) on Wednesday, January 28, 2009, in the Kepulauan Batu region, 220 km SSW of Sibolga, Sumatra, Indonesia, at a depth of 35 km.
A strong magnitude 6.2 earthquake occurred at 20:16:34 (UTC) on Thursday, January 22, 2009, in the Kepulauan Barat Daya region, 316 km WNW from Saumlaki, Tanimbar Islands, Indonesia, at a depth of 141.1 km.
Bad news for the survivors of the 2004 Indian Ocean tsunami: Neither the giant earthquake that triggered the killer wave nor the hundreds of smaller temblors that followed have exhausted the area's pent-up seismic energy, a new analysis reveals. The potential remains for a quake large enough to set off another devastating inundation.
A strong magnitude 6.1 earthquake occurred at 19:22:02 (UTC) on Monday, November 03, 2008, in the Nias region, 168 km WSW from Sibolga, Sumatra, Indonesia, at a depth of 28 km.
The Indian Ocean tsunami in 2004 was not the first of its size to hit the region, according to new research. Two international collaborations have sampled the sediments in Thailand and Sumatra to examine tsunami history. At both sites, there was evidence of sediment laid down by a large tsunami between 600 and 700 years ago, pre-dating written and oral records.
The tsunami that killed 230,000 people in 2004 was the biggest in the Indian Ocean in some 600 years, two new geological studies suggest. That long gap might explain how enough geological stress built up to power the huge undersea earthquake that launched the killer waves four years ago, researchers said.
A strong magnitude 6.1 earthquake occurred at 11:15:41 (UTC) on Tuesday, September 16, 2008, in the East Timor region, 140 km ESE of Dili, at a depth of 44.4 km.
A strong magnitude 6.2 earthquake occurred at 00:00:10 (UTC) on Sunday, September 14 2008, in the East Timor region, 150 km East of Dill, East Timor, at a Depth of 35 km
Tsunami alert A tsunamis alert has been issued after a strong earthquake shook eastern Indonesia.
