The latest issue of the Seismological Review Letters (SRL) contains some interesting papers on strong earthquakes, seismicity, and tsunamis. Here’s a list of papers that could be especially interesting for the paleoseismicity community: more
I am not entirely sure why the following video was produced, what it is aiming for and if it should be used in geoscience education, but I like it. It very nicely illustrates what a green potato would experience if it was on a cruise ship, from there went down to the seafloor with a yellow submarine, was trapped by a submarine landslide and subducted into the Calabrian Arc and then by using a time machine spit out by Stromboli volcano or so. I always wanted to learn about this. more
Last year we’ve seen some surprising seismic events. Do you remember the two strange events of M8.6 and M8.2 off Sumatra? We didn’t even know that such strong strike-slip events were possible, and those two earthquakes ruptured in a weird rectangular pattern AND occured within few minutes of each other. Do you remember the third most powerful EQ that rattled the Okhotsk Sea? No? Well, I think it’s a good idea to have a look at the strongest events that happened last year. more
A new story came up recently that sounds like the L’Aquila case, but the other way round. Dr. Roger Bilham from the University of Colorado, a well-known earthquake researcher, was denied entry to India earlier this year. He was on a flight to Bhutan and supposed to change planes in New Delhi when Indian officials sent him back to the plane he just arrived on. Officially, he was accused with having the wrong type of visa. Himself and many colleagues, however, are sure that he was deported because he stated that the seismic hazard in India is underestimated. more
It’s Friday, friends, the weekend is near and here’s the Friday links. Today I collected some news on earthquakes, landslides and geoscience jobs. Have fun!
A new paper was just published on Active faulting in the north-eastern Aegean Sea Islands. Our colleague Alex Chatzipetros and his co-authors investigated the distribution of seismicity and faulting pattern at the islands of Lemnos, Aghios Efstratios, Lesvos, Chios, Samos and Ikaria. From this data and field analyses they concluded on the effects of active faulting on the local geomorphology. more
A strong earthquake rattled Japan today and caused some intense shaking in the Fukushima region. The quake had a magnitude of 7.3 and occurred at a depth of ~30 km. A tsunami warning was issued immediately, but until now (11:30 CET) it looks like no waves were created. more
So many things are said to cause earthquakes, things have become a little complex during the last years. For many people it might be hard to remember all of them and you will probably ask yourself “What can I do to avoid finding myself having caused a seismic event by accident?” Here’s help. I prepared a list with no claim to completeness of things that might cause earthquakes. Some are already well-known, some were suprising to me. Recently, chancellor Angela Merkel said she’s against equal taxation for gay and straight couples. I guess this can only be interpretetd as an attempt to minimize seismic hazard in Germany, everything else would be ridiculous…

Paleoseismicity.org is a page dedicated to scientists and everyone else interested in paleoseismology, archeoseismology, neotectonics, earthquake archeology, earthquake engineering and related topics. Different authors irregularly write about recent papers, field work, problems, conferences or just interesting things that they come across. We intend to provide a platform for discussion and scientific exchange. Interested in joining as an author? Please contact us!
