What’s up? The Friday links (41)

Although I already recommended some papers earlier this week, I have two more to mention: Supawit Yawsangratt and colleagues published new data on “Evidence of probable paleotsunami deposits on Kho Khao Island, Phang Nga Province, Thailand”. Nat Hazards, 63,151-163, DOI 10.1007/s11069-011-9729-4 in a special issue dedicated to tsunami research. Ran et al. presented work on the Wenchuan EQ epicentral area: “Paleoseismic events and recurrence interval along the Beichuan -Yingxiu fault of Longmenshan fault zone, Yingxiu, Sichuan, China.” Tectonophysics (2012), doi: 10.1016/j.tecto.2012.07.013.

The Rio-Antirio bridge that spans the Gulf of Corinth - designed to withstand a M7 earthquake. A good idea in this area, which is among the fastest spreading grabens we know.

New excavation at Baelo Claudia

Those of you who attended the INQUA-IGCP workshop in Baelo Claudia in 2009 already know some parts of those beautiful Roman ruins and the earthquake damage there. Now archaeologists excavated new thermae. I am excited if they will have archaeoseismological features, too:

Building near faults

At the SSA meeting in San Diego this year the Joyner lecture was one of my personal highlights. Jonathan Bray spoke about building near faults and explained what engineers nowadays are able to do if one can not avoid to built near active structures. You can now listen to his talk at this USGS site and see the slides! Great!

Geo-beer

Silver Fox from Looking for detachment has a nice post on geo beer. Ichthyosaur Icky IPA.  Bad luck it looks like they don’t ship to Germany…

Maps of mines in Europe

There’s a nice map with the active mines of Europe, at least with the major ones. It’s not free but looks like a nice gift.

Archaeoseismological evidence for EQs in the Ardennes

The Association des Géologues du Bassin de Paris posted some nice images on its Facebook site, apparently showing archaeoseismological evidence for the 1692 earthquake: Séismes et tectonique en Ardenne belge. I can’t speak French, unfortunately…

Turbidites and Paleoseismology

USGS published a huge report on the “Turbidite Event History – Methods and Implications for Holocene Paleoseismicity of the Cascadia Subduction Zone“.The work comes in the frame of the Earthquake Hazards of the Pacific Northwest Coastal and Marine Regions, USGS Professional Paper 1661, edited by Robert Kayen. Download the report as pdf here.

Strange picture of the Bosnia and Herzegovina M4.5 EQ 2012-07-30

On 30 July, 2012 (Monday), a magnitude 4.5 earthquake occurred in Bosnia and Herzegovina in very shallow depth. The mechanism was soon determined as strike slip:

Moment tensor solutions. Image by EMSC-CSEM.

The quake was felt widely and intensities reported were up to VI. EMSC has an image gallery with damage photos, and they show mostly light damages only. However, there is one image showing a kind of surface rupture that is very strange. We would not expect this in a M4.5 event, right? Click here to view image.

 

 

Have a nice weekend!
