4.8 earthquake strikes beneath Kilauea Volcano; several aftershocks follow

August 12, 2013HAWAIIThe U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) recorded a 4.8 magnitude earthquake beneath the Big Island early Sunday morning. It was recorded at 5:54 a.m. about 5 miles south of the summit of Kilauea Volcano and at a depth of about 20 miles. Several aftershocks followed, the largest of which was a 3.4 magnitude earthquake at 6:06 a.m. According to Wes Thelen, HVO’s Seismic Network Manager, “these earthquakes were most likely structural adjustment of the Earth’s crust due to the weight of the island on the underlying mantle.” Many Big Island residents reported feeling the shaking and the HVO says people as far away as Oahu and Maui reported feeling the earthquake. Almost 400 reports received within the first hour of the earthquake. No injuries were reported. –Khon2

    As as part of Hawaii is shaking and exploding, Florida is still sinking.

    I loved the fancy speak “structural adjustment of the Earth’s crust due to the weight of the island on the underlying mantle” explanation.. in otherwords mantle slippage, just like *any* earthquake. The only difference is that under *this* particular mantle is a whole lot of lava pressing up, so it could mean that now a real big one is on the way, if the new position is more unstable than the old one…

    Hi All. I am not a geologist by any stretch of the imagination, but I have been told by fairly knowledgeable people that the South East coast of the Big Island is very unstable. If fact, a massive collapse of this coast is not only likely but inevitable due to the unstable construction of the base. When it goes, it has the possibility of creating a large tsunami aimed at Mexico, California. and Oregon. Not too sure how true all of this is but I guess it’s possible.
