Samoa earthquake 2009
10.01.2010
The 2009 Samoa earthquake was an 8.0 Mw submarine earthquake that took place in the Samoan Islands region at 06:48:11 local time on September 29, 2009. It is the largest earthquake so far in 2009. A tsunami was generated which caused substantial damage and loss of life in Samoa, American Samoa, and Tonga. The Pacific Tsunami Warning Center recorded a 3-inch (76 mm) rise in sea levels near the epicenter. The quake occurred on the outer rise of the Kermadec-Tonga Subduction Zone . This is part of the Pacific Ring of Fire, where tectonic plates in the earth's lithosphere meet and earthquakes and volcanic activity are common. The earthquake occurred less than 1 day before the 2009 Sumatra earthquake, a magnitude 7.6 earthquake and subsequent aftershocks in which at least 715 died. Countries affected by the tsunami in the areas that were hit are American Samoa, Samoa and Tonga where more than 189 people have been killed, most of them in Samoa. Large waves with no major damage were reported on the coasts of Fiji, the northern coast of New Zealand and Rarotonga in the Cook Islands. People took precautions in the low-lying atolls of Tokelau and moved to higher ground. Niue was reported as reasonably safe because it is high. There have been no reports of high waves from Vanuatu, Kiribati, New Caledonia and the Solomon Islands.

Most of the warnings were called off once it was clear that the tsunami threat had passed. Officials in the Cook Islands, which is currently hosting the 2009 Pacific Mini Games, noted that the tsunami passed without any damage to the country. A tsunami warning remained in effect for the Marquesas Islands of French Polynesia, as five main waves were expected to strike that archipelago. Warnings also remained in Tuvalu, one of the lowest lying countries in the world Local radio stations in Tonga broadcast warnings that a tsunami was possible and that people should move away from coastal villages A tsunami watch was issued for islands farther from the epicenter, including Hawaii and Papua New Guinea, but not for California, USA. Officials were determining whether the tsunami could reach Hawaii, the center said. It was possible that a strongly decreased wave could reach Hawaii. A tsunami advisory was issued for coastal California and the San Francisco Bay Area beginning at 9:00 PM local time as a precaution Only aftershocks with magnitude 5.5 or higher are listed. There were more than 40 total aftershocks with a magnitude greater than 5.0 in the 48 hours since the initial earthquake.
