Today is the 200th anniversary of the first event of the New Madrid Earthquake Series. There’s still an open debate on magnitudes, intensities, causative faults, recurrence intervalls and the implication for seismic hazard. Several websites and blogs have nice posts, among them:
Retos Terrícolas started a nice article series on the Messinian Crisis, including videos on how the Mediterranean dried out. The reason is a recent Nature article:
Garcia-Castellanos, D., & Villaseñor, A. (2011). Messinian salinity crisis regulated by competing tectonics and erosion at the Gibraltar arc Nature, 480 (7377), 359-363 DOI: 10.1038/nature10651. Read part 1, part 2, part 3. All articles are also available in Spanish, muy bien! Here’s the video animation:
It shows some differences to what I know from the literature, especially when it comes to the last open connections from the Atlantic to the Med, but the animation is nice and well done.
Is there really a North-American plate? Maybe not, according to Allan Krill.
Google StreetView has amazing images from the area that was hit by the Tohoku Tsunami. You can compare images before and after the tsunami and see the enormous devastation. Really impressive and also valuable for science.
Have a nice weekend!
