Powerful Earthquake Strikes Banda Sea

Posted by feww on October 25, 2009

Powerful Quake Measuring up to 7.3 Magnitude Strikes Banda Sea

A powerful earthquake measuring up to 7.3 Mw struck Banda Sea about 40 km WNW of Serua volcano and 65 km south of Manuk volcano, on Saturday, October 24, 2009 at 14:41 UTC.

The quake occurred at 6.161°S, 130.346°E, some 230 km  NNW of Saumlaki, Tanimbar Islands, Indonesia, at a depth of about 140 km. It was followed by a moderate quake measuring up to 5.3 Mw, which struck at 6.749°S, 131.601°E, on Sunday, October 25, 2009 at 00:35:06 UTC.

On February 21, 1938, a large quake measuring M 8.5 struck about 185 km northeast of Saturday’s quake  at a depth of 25km.

FEWW Forecast:

Based on an analysis of seismic activity in the region, FEWW Moderators believe a large earthquake measuring up to M 8.6 could strike Banda Sea in the next 3 – 6 months. Additional events measuring 6.0 to 7.6 Mw could also be expected in the region, anytime.

Population Exposure:

Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. A magnitude 6.6 earthquake 360 km Northwest of this one struck Indonesia on March 12, 1983 (UTC), with estimated population exposures of 126,000 at intensity VII and 204,000 at intensity VI, with no reported fatalities. On June 17, 1987 (UTC), a magnitude 7.1 earthquake 82 km Northeast of this one struck Indonesia, with estimated population exposures of 1,000 at intensity VI and 82,000 at intensity V, with no reported fatalities.
