ETH best place to study geosciences in Europe and third best in the world!!!
The ranking of the world's best universities for Geosciences has just being released and ETH made it to the third place. We lead Europe in Geosciences. The ranking can be found here.
In addition to rankings of the world's top 500 universities overall and by region and country, the inaugural U.S. News Best Global Universities rankings include an examination of the leaders in key academic subject areas. U.S. News used a separate methodology to publish the top 100 global universities in 21 subject areas. The subject rankings are powered by Thomson Reuters InCitesTM research analytics solutions.
Sinabung, Sumatra, field campaign 2014.
With colleagues of BMKG we went to sample the products of the recent eruption of the Sinabung volcano. The volcano, inactive for more than 1000 years began to erupt in 2010 with a phreatic explosion. Then, in 2013 a dome was extruded and pyroclastic density currents run down the SE flank of the volcano destroying villages and the resources of an entire community. When we arrived we found harsh conditions and a volcano extremely difficult to sample due to the ongoing activity and the lack of fallout deposits. I posted some photos here to share.
Finally the Corrigendum on LUSI is out
To read it click here. The LUSI is still one of the most debated subjects of the last years in Geosciences. In comparison to the original paper, the main point that we address in the is that new (and previously unavailable) data highlight that the high-velocity seismic reflector at the top of the bluish grey clay was apparently an artefact introduced when inverting the borehole data. Instead, the borehole log show that Vs go down to 380 m/s at 1 km indicating extreme overpressures within the bluish grey clay formation. The log data are available as additional material in the corrigendum. Check the animation of a plane wave from below here.
See you at EGU?
The highlight is session SM3.4/ERE5.2
Induced and Triggered Seismicity: Theory and Observations (co-organized)
In addition we will be presenting several abstracts.
See you at AGU?
I will be attending the AGU 2013 meeting in San Francisco. The talk on LUSI mud volcano, Indonesia will be on the 13th of December in the 3014 (Moscone West), session H52D. There will also be a poster on the 12th of December about seismic activity triggered by the Maule earthquake at the Hall A-C (Moscone South).
If you are interested in fluid flow then we can meet at the Hubbert Quorum on Sunday at the USGS head quarters in Menlo park
Cover story of Nature Geoscience, chek it here.
Another interesting article was published this morning on News & Views in Nature Geoscience. Paul Davies comments on the LUSI debate and underlines a point that we might have not stressed enough in the paper. He says: The calculations by Lupi et al. were simplified into two dimensions and may underestimate the amplification effect by up to five times compared with the three-dimensional scenario
we did not underline that we presented a worst-case scenario and the
effects induced by the seismci waves might have been even stronger.

Also ETH Life presented a nice comment about our work, click here to chek it.
The catastrophic mud eruption in Indonesia blamed on drilling by an oil company might instead have natural causes, new research suggests.

Mini Workshop on the 2012 Emilia earthquake
A nice mini workshop on the 2012 Emilia earthquake was organised by Dott. Marzia Conventi from the Comune of Fiorano on June 8th, 2013 in Nirano, Italy. I presented the first results from the study that we carried out with colleagues from Bonn. A short summary of the day can be found here (in italian only).
