A paleoseismological trench has been opened at San Carlo – Sant’Agostino. At this place, liquefaction features and other environmental earthquake effects were recognized after the Finale Emilia earthquake of 2 May 2012, magnitude MW6.1. The trench reveals normal fault features close to the surface. Our colleague Alex Chatzipetros from Earthquake Geology of Greece posted a great article on the trench work and has all the interesting photos. more

What’s up? The Friday links (34)
June 7, 2012 | in The Friday LinksOne of the best blog articles I recently read deals with the problems scientists face when they are interested in public outreach. Scicurious perfectly summarizes our situation.
The transit of Venus was a spectacular event, unfortunately not visible from Aachen. A really great photo collection is here at The Big Picture (Boston.com). A cold comfort for those who missed it (like me). They always have the best pictures there, by the way. more

Data sources for the Finale Emilia earthquake (Mw6.1)
June 4, 2012 | in EarthquakeMore than two weeks have gone now after the Mw6.1 earthquake in Northern Italy, and a very strong aftershock has rattled the area again and caused casualties and more buildings to collapse. Several reports are already published on that event and we have lots of data which is waiting to be analyzed. Here’s a summary of data sources: more

Finale Emilia earthquake: preliminary report on Earthquake Environmental Effects (EEEs)
May 31, 2012 | in EarthquakeThe University Insubria (Como, Italy) has published the first report on the earthquake environmental effects that accompanied the Northern Italy “Finale Emilia Earthquake” of 20 May, 2012. On that day, a quake with magnitude Mw6.1 rocked the Po Plain, leaving seven people dead and hundreds of houses damaged. On 29 May, a very strong M5.8 aftershock occurred in the region. more

New data from the Northern Italy Mw6.1 earthquake (20 May 2012)
May 21, 2012 | in EarthquakeThe INGV has published some new data on the earthquake that hit Italy in the morning of 20 May, 2012 and caused damages and casualties. Peak ground accelerations (PGA) reached 28%g in the epicentral area. This is not unusual for an event of that size. Peak ground velocities (PGV) were as high as 20 cm/s. The spectral response is more interesting. The 3s period response is 1.5%g only, at 1s period the area encountered 18%g, and for the 0.3s period the values reached 49%g, which is quite a lot for a Mw6.1 quake. However, the longer periods tend to be more dangerous for buildings. more

Mw6.1 earthquake rocks Northern Italy
May 20, 2012 | in Earthquake | 2 responsesAn earthquake of magnitude Mw6.1 (EMSC data; USGS: M6.0) rocked Northern Italy on 20 May, 2012 at 2 am UTC. The epicentre was located on 35 km NNW of Bologna in the Po Plain at around 10 km depth. Media report at least 6 people dead and up to 50 injured. Intensities reached up to EMS VIII. Especially old brick buildings suffered severe damages and many collapses are reported. more

What’s up? The Friday links (24)
December 2, 2011 | in The Friday LinksEarthquake prediction is possible! At least for toads (well, for bufo bufo only). And at least in Italy. And at least in 2009. Do you remember that story of toads having left their home (lake) before the L’Aquila earthuake and returning after the aftershock sequence? A new paper on this was published in the International Journal of Environmental Research and Public Health: Grant et al., 2011: Ground Water Chemistry Changes before Major Earthquakes and Possible Effects on Animals. Int. J. Environ. Res. Public Health, 8, 1936-1956; doi:10.3390/ijerph8061936.

New paper on L’Aquila earthquake
October 1, 2011 | in PaperBased on a new inversion of InSAR data, De Natale et al. predicted that the Avezzano and Sulmona tectonic domains, in Central Italy, may anticipate by 15-20 yr the next large earthquake, as a result of stress transfer. Avezzano and Sulmona were razed by a large earthquake in 1915 and 1706, respectively.
