In the framework of IGCP567, Dr. Andrey Korjenkov is convening a special IGCP567 session and field trip on Earthquake Archaeology and Palaeoseismology in Central Asia.
All information on the international symposium can be found in the first circular (and registration form).
If you are interested to contribute to this session and/or participate to the field trip, please contact Dr. Korjenkov (akorjen@mail.kg) as soon as possible. The final deadline is 15 March.

I have won my first WoGE on Friday, Florian had a great image of the Okavango delta in Botswana. So I have the great pleasure to host the actual quiz. The rules are simple: Find out the position of the image placed below (provide coordinates) and give a short description of the geological features in the comments. The first to find out has the honor to host the next quiz on his (geo-) blog. I do not invoke the “Schott rule” since I chose to show only a small detail of the subject of interest. This means: Let the games begin! more
The Christchurch earthquake was the main topic of the Geoblogosphere this week. A great analysis on the effects was provided by Dave Petley in his Landslide Blog. Highly Allochthonous reasoned on seismic lensing, Ontario Geofish posted a lot on building security, and countless news sites came up with photos and reports. Frank Taylor, who hosted the GoogleEarthBlog before he left for a sailing trip around the world, was in Christchurch next to the Cathedral when the quake happened. On his Tahina Expedition website he reports on his experiences.

A M6.3 earthquake hit Christchurch, New Zealand on 22 February (21 Feb in UTC), leaving at least 75 people dead and hundreds injured or missing. Hundreds of houses were destroyed, including the Christchurch Cathedral, and damages will probably sum up to some billion dollars. On 4 September 2010 (3 Sept in UTC), a M7.0 event struck Christchurch, but then no one was killed. So: what’s the difference between the two events?

A nice short discussion about the Lorito et al., 2011 paper regarding the seismic gap at the Chilean coast and seismic slip during the 2010 earthquake, can be found at Highly Allochthonous. The discussion highlights the paper findings under the glance of the recent Bio-Bio earthquake from Friday, which took place in this so called Darwin gap.
The registration for the 2nd INQUA-IGCP 567 International Workshop on Active Tectonics, Earthquake Geology, Archaeology and Engineering at 19th-24th September 2011 in Corinth, Greece is opened.

Today on Friday, 11 February, a magnitude 7.0 earthquake occurred offshore in Chile near Concepcion at 36.5° S and 73° W in a depth of 28km. The MMI at the nearby large cities was reported by the USGS with V.
Update: The magnitude was corrected to 6.8. The earthquake was followed one hour later by a further event with a magnitude of 5.3 and 4 hours later again by a more shallow 6.3.

The Accredtionary Wedge #30 blog carnival hosted by Mountain Beltway came up with a tasting idea in January: The Geological Bake Sale. Explore and enjoy thematic food like the moon surface cake, the pillow lava bread and the debris flow vegetables. If you create a sweet fault or a tasty trench, we promise to publish it on paleoseismicity.org. more
