What’s up? The Friday links (58)

It’s time to revive the Friday Links tradition, I just realized that it fell asleep in March…

A paper published in Science few hours ago deals with the energy release of one of the strangest mega-quakes that we have ever observed, the M8.3 Okhotsk event of 24 May 2013. The interesting thing is that is occurred in more than 600 km depth! In the same issue of the journal another paper describes attempts to perform analogue experiments of such events in the lab. If you just want to get a rough idea about the studies or have no access to science, I recommend to check out Andrew Alden’s article at kqed science.

Ancient landslides in Ottawa a clue to the local paleoseismicity

A recent study analyzed large landslides in Canada and correlated them to strong earthquake events. Rather bad news for the seismic hazard there. The Ottawa Citizen has a round up. Also the post at the Landslide Blog.

Large landslide in Mexico

The two severe storms that caused massive floodings in Mexico also lead to a number of large landslides. One of them, the event at La Pintada, has likely killed more than 60 people. Dave’s Landslide Blog has images and the -sad- story.

Fukushima and the Ocean

Recently, only bad news reached us from the Fukushima Power Plant. Leaking tanks, contaminated groundwater and so on. The Oceanus Magazine has dedicated its recent issue to Fukushima. Worth reading.

Mount Sinabung erupts

In Indonesia, Mount Sinabung has erupted and produced an impressive ash cloud. Don’t miss these impressive pictures at the BBC website. In this video, the action starts at 0:30 min:

Lots of short papers on landslides and earthquakes, tsunamis

Springer has published part V of Landslides Science and Practice with a number of papers on tsunami- and earthquake related landslides. Check out the Index here.

Hellenic Macroseismic Database

The Hellenic Macroseismic Database is online. Great data source and also interesting for archeoseismological studies, based at the National and Kapodistrian University of Athens.

Have a nice weekend!
