What’s up? The Friday links (27)

Recently, scientists from Switzerland came up with the news that fractured bedrock might amplify earthquake shaking. The say they observed an increase by factor 10, which seems huge. I knew amplifying by sediment basins, but this is new to me.

100 years ago on 6 January, Alfred Wegener presented his continental drift theory for the first time. The Blogosphere was full with articles, among them:

You think you already know everything about Alfred Wegener and you’ve read everything about his theory? Well, check out this song:

Another really great video I found does perfectly explain why many small earthquakes do not release sufficient energy to avoid a big one:

Tom brought my attention to this video – a sonification of the Tohoku earthquake in Japan:

The Virginia earthquake was huge surprise to the people at the eastcoast. Chuck Bailey hast two nice posts on this event: Part 1, Part 2.

Now scientists say there’s no linkage between fracking and the Virginia earthquake. This discussion has become virulent during the last months and I am looking forward more data.

Most of you, dear readers, will have read a Lonely Planet Tour guide, I guess. Now they updated their entry on Christchurch, NZ, stating that this is an “exciting city”, because of the aftershocks. Can you believe this? Will they add a category for geological risks?

Just one more suggestion to everyone in Western Europe: On Friday, 24 January, Koji Okamura will give a guest lecture at Leuven University, Belgium: Lessons learned from the March 11, 2011 Tohoku-oki earthquake and tsunamis. The lecture starts at 3 p.m. and will be held at KAST 01.07, Kasteel Arenberg, Heverlee. Download the anouncement (PDF) here.

Don’t miss the EGU abstract submission deadline and have a nice weekend!
