Less of the Scary Geology, Please

17 08 2007

An overwhelming day, geologically speaking. Front and center, of course, is the horrific 8.0 earthquake in Peru that killed over 500 people. Fellow geo-blogger Miguel Vera posted in depth about it from Lima, Peru, in Spanish and included some YouTube videos. For Anglophones, an excellent article in the New York Times explains the movment of the Nazca plate which causes the strong earthquakes in this beleagured part of the world. I won’t comment more on this event, because there are so many new stories and you’ve probably read all about it.

Following the Peru earthquake, a small tsunami hit Japan., causing vacationers to evacuate beaches. There were also two very deep earthquakes in the waters off Indonesia early today but they did not result in a tsunami warning.

According to the Seattle Times, satellite images of the volcano taken Thursday showed strong thermal readings, consistent with what the Alaska Volcano Observatory is calling a “vigorous eruption of lava.” Lava flows that melt the snow on the top of the volcano can cause mudslides, that may in turn trigger seismic activity.

(This past weekend, Ethopia’s live volcano, Mount Erta, in the northeatern partof the country, erupted, causing villagers to flee its lava flow.)

Today’s 3.5 jolt in L.A. was nothing, really. Just a bump.
