Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Powerful Aftershocks Still Striking Solomon Isles

Posted by feww on January 6, 2010

Aftershocks Continue to Strike Solomon Islands

Seven fishermen from Viru in the Western Province were reported missing amid continuing aftershocks, the Solomon Star newspaper reported. The seven have not been seen since Monday’s mainshock and tsunami.

As of posting, 8 more aftershock Measuring greater than M5.0 have struck near the epicenter of the mainshock that occurred on January 4. See:

The largest of these aftershocks measured up to 7.2Mw.

The Solomon Islands region, which comprises a section of the Pacific Ring of Fire, is particularly prone to earthquakes because of the above average rate of convergence of the Australia and Pacific tectonic plates in the region.

The down-going slab of the Australian plate is overridden by leading edge of the Pacific Plate at a rate of about 10 cm/yr near the location where the shocks occurred.

As the subducting plate is forced into the earth’s mantle, the more brittle areas of the crust is crushed resulting in the release of stress energy—earthquakes.
