What’s up? The Friday links (25)

It seems like everyone is at the AGU currently, and even the German media is full of geoscience news. The first really interesting thing that I came across was that hurricanes might trigger strong earthquakes. If Shimon Wdowinski from University of Miami is right, this would be a huge step forward for our earthquake understanding. If he should be right.

Susann from Geology in Motion presented new estimates of the energy of the Tohoku (Japan 2011) tsunami and concludes that it had about 400 petwatts! 400,000,000,000,000,000 W. My car has 45,000 W.

Helen Shen from Geospace reports on how the Tohoku tsunami triggered small earthquakes in California. Fascinating story.


Rapid Uplift has a nice article on earthquakes in India – more paleoseismological work is urgently needed to determine seismic hazard there!


En Tequila es Verdad brought my attention to one of the best plate tectonics songs I’ve ever heard: Breaking up is hard to do.

Of course there was that fascinating story of the merging tsunami. The Japan 2011 (Tohoku) tsunami was imaged by stallites and they found that two waves merged and doubled its power on the way to the eastern Pacific. Almost all mainstream media got it wrong and wrote that the waves hit Japan with twice the power. No. Not Japan. The US West Coast. Thanks to Geology in Motion again to clarify that.

A rather unexpected earthquake hit Western Australia this week, M5.1. Nothing happened because no one lives there, but we’ve seen shallow M5 earthquakes that really caused some damage. Remember Lorca.

Have a nice weekend!!
