Today is GeoScience Day (Geotag) at RWTH Aachen University! Organized by the Chair of Engineering Geology and Hydrogeology, this event will start at 9:30 am in the Couvenhalle, Aachen. Geoscience-related talks and a poster exhibition will only be some parts of the very interesting program. The Geo summer party will be started after the “Geotag” at 6:00 pm at the parking lot of the Geoscience Institute at Wüllnerstraße. Come and see! Follow the Geotag on Twitter (hashtag #GEOTAG) and Facebook, and visit the official website! more

The Gulf Stream is ensuring the mild climate in Europe, everyone knows that. But does it really? Read Chris Rowan’s article on climate, Gulf Stream, heat capacity and atmospheric circulations.
Ritz et al. published a paper on the paleoseismicity of the North Tehran Fault, Iran. From trenching studies they claim at least 6 surface-rupturing events during the last 30 ka. Read the paper here at JGR-Solid Earth. Ritz, J.-F., H. Nazari, S. Balescu, M. Lamothe, R. Salamati, A. Ghassemi, A. Shafei, M. Ghorashi, and A. Saidi, 2012: Paleoearthquakes of the past 30,000 years along the North Tehran Fault (Iran), J. Geophys. Res., 117, B06305, doi:10.1029/2012JB009147. more

Three papers published recently caught my eyes. First, Andrej Gosar investigated the earthquake environmental effects (EEEs) of the 12 April 1998 Mw =5.6 Krn Mountains earthquake, Slovenia. The quake measured VII-VIII on the EMS-98 scale, and Andrej found that the intensities reached the same values on the ESI2007 scale. He reports that the intensity distributions for both scales are comparable, but show some differences due to the sparsely populated epicentral area. The research concentrated on rockfalls for EEE determination. It’s a nice example that also moderate events can be characterized using the ESI2007 scale.

Earthquake prediction again: The former president of India, Abdul Kalam, said earthquake prediction will be possible within 10 years. It would be great if he was right, but he isn’t. Why do people continue to say that? There are so many that “predict” earthquakes, and so many people relying on them. What a pity… more

An earthquake with a magnitude of Mw9.0 has occured 130 km east of Honshu, Japan in a depth of ~25 km. This had been the fourth or fifth strongest earthquake to be recorded by instrumental seismology. The quake caused significant destruction to the Honshu Island and triggered a tsunami that destroyed a number of harbours. In some places (Sendai), tsunami heights were reported to exceed 10 m. A tsunami warning has been released for wide parts of the Pacific, but in Hawaii only 1 m was observed, therefore the warnings for the US West Coast have been lowered. more

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?
