  • English report on the Mw5.1 Lorca earthquake out now

    2011-07-07 | Christoph Grützner in Paper

    The preliminary report on the Lorca Mw5.1 earthquake from 11 May 2011 is now also available in English! The quake caused a lot of damages to building despite the relatively low magnitude. One building collapsed and nine people died. The report summarized the geological background, environmental earthquake effects and damaged infrastructure. more

  • The Wednesday Centerfault (6)

    2011-07-06 | Christoph Grützner in Centerfault

    This day’s Centerfault is one of the longest and best investigated faults in Spain, the sinistral Carboneras Fault Zone (CFZ) in Andalusia (36.85°N, 2.25°W). In the north, the CFZ is bounded by the Palomares fault, its southern tip reaches the Gulf of Almería. The NE-SW striking fault zone stretches over 50 km onshore and additional 100 km offshore (Gràcia et al., 2006) and is, therefore, capable of earthquakes with magnitudes > 7. It is one of the three major strike-slip faults in the Betics (Bell et al., 1997). more

    In April 2011 we started on a field trip to investigate the Padul-Nigüelas Fault Zone in Spain (+/- 37°N, 3°36°W, see map here). Like the Wednesday Centerfault (5), the PNFZ is in the Granada Basin but some 40 km ENE. Delimiting Tortonian to Quaternary basin fillings to the Sierra Nevada, the PNFZ forms hardrock scarps. more

  • The Wednesday Centerfault (5)

    2011-06-01 | Christoph Grützner in Centerfault

    After we dealt with some faults in Greece, let’s move to Spain. The Ventas de Zafarraya Fault (VZF) west of the Granada basin (36.96° N, 4.14°W) has a beautiful morphologic expression and an exciting history. The fault bounds the Zafarraya polje to the south, with Quaternary sediments to the north (hanging wall) and limestones of the Internal Subbetics in the footwall. more

  • What’s up? The Friday links. (2)

    2011-01-14 | Christoph Grützner in The Friday Links

    On Wednesday night the Etna on Sicily showed strombolian activity and glowing lava flows were visible from Catania. Don’t miss the great photos here and the webcam of the INGV and EtnaTrekking. This is the first larger eruption since May 2008 and surely one of the most beautiful ones. News coverage with more great videos here.

  • “spektrumdirekt” reports on archeoseismology

    2011-01-04 | Christoph Grützner in Paper | 3 responses

    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
