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 volunteer panel that assesses earthquake risks in Utah said it examined nearly 130 school buildings in the state and found more than half fail to meet federal earthquake safety guidelines. Bad news from here.

The Alaska Science Center is advertising five new permanent research geologist positions. Applications are open between December 1, 2010 and February 15, 2011, and that selection will occur during late spring of 2011. More information on their homepage, including the following announcement:
“This hiring initiative inaugurates a team approach to geologic research in Alaska (Photo gallery). The five positions will together make up a working group that will respond to the USGS’ ongoing need for research in framework geology of the 49th state. Project work is expected to support a broad range of research topics related to crustal evolution and surficial processes. We expect projects will involve collaboration with researchers from other USGS offices, federal agencies, state agencies, and academia.

On 4 January, 2011 a partial solar eclipse was visible in Central Europe (up to 80% coverage of the sun). Werner Kraus shot some nice photos through a number of filters, but the best picture surely has been made by Thierry Legault from Muscat, Oman – the partial eclipse with the ISS transiting! Incredible.

The online science magazine “spektrumdirekt” reports on the archeoseismological and paleoseismological studies in Baelo Claudia, Southern Spain. The article focusses on tsunami hazard in the Mediterranean region and the two earthquakes that devastated the Roman town of Baelo Claudia hundreds of years ago. more

Paleoseismology and archeoseismology do only rarely appear in the curriculae of geoscience studies. Those topics will be covered in courses on tectonics and structural geology in most universities. Practical courses that allow applying the knowledge in the field can be a very good supplement, but in Germany, active faults are rare. RWTH Aachen University therefore organized a field trip to Greece, where active faults, fault scarps, archeological sites and beautiful outcrops are omnipresent.
