It’s been a while since the last Friday links, so today’s list is rather long. Of course the Russian meteoroid-meteor-meteorite (yes, in this order!) was an absolutely amazing, though destructive phenomenon. The air blast was registered equivalent to an earthquake of magnitude 2.7. Read Livescience’s article here and read this text to get to know about meteors and seismograms in general. more

New paleoseismology papers in BSSA
2013-02-19 | in PaperSeveral paleoseismology papers have been published in the latest issue of BSSA (103-1). There’s interesting new data on faults in New Zealand, California, and several regions in China, Taiwan and India. For sure I will read the following papers: more

Small tsunami hits Solomon coast – M8 earthquake and fifty aftershocks
2013-02-06 | in Earthquake | one responseIn the last twelve hours, a series of major earthquakes struck the Santa Cruz Islands. Beginning with the activation of a thrust fault with a M8.0 (M7.9) earthquake, almost fifty aftershocks hit the region. A regional tsunami warning was released short six minutes after the first quake at 1:12 UTC and has now been cancelled.

Earthquakes in Austria/Slovenia and Japan
2013-02-03 | in EarthquakeOn 2 Februar, a magnitude 4.5 earthquake occurred in shallow depth (~2-7 km) directly at the border between Austria and Slovenia. USGS reports an oblique-slip focal mechanism and a magnitude of Mw4.0 only. According to the Austrian Zentralanstalt für Meteorologie und Geodynamik the quake was felt widely and even in Vienna. Very light damage has been reported from the epicentral area. more

What’s up? The Friday links (55)
2013-02-01 | in The Friday LinksWe’ve seen several magnitude 6 earthquakes last week. On 28 Januar, a shallow M6.1 strike-slip event occurred in eastern Kazakhstan. A little surprise only, we knew about thrust mechanisms in this area, but of course some strike-slip movements do not change the big picture. Would be interesting to check for surface ruptures. This is, by the way, the study area of our friend and colleague Angela Landgraf. Maybe we can convince her to write something about the paleoseismological background of that area? more

What’s up? The Friday links (54)
2013-01-25 | in The Friday LinksSomething many people have been waiting for happened last week. Judge Marco Billi explained his verdict in the L’Aquila case. In a 950 page document he published the so-called “motivazione”, stating that “the deficient risk analysis was not limited to the omission of a single factor, but to the underestimation of many risk indicators and the correlations between those indicators.” This should have been understood by the scientists, but instead they delivered a “superficial, approximate and generic” analysis. more

Explaining paleoseismology using the 1000 most common words only
2013-01-19 | in paleoseismicity.org | 3 responsesA nice meme is currently having success in the geoblogosphere. Originating in XKCD’s up-goer five explanation of a space rocket using only the 1000 most common English words, dozens of geobloggers already explained what they are doing in simple language. Anne over at Highly Allochthonous has collected the results, and she and Chris already set up a tumblr-page for collecting the texts. Try on your own using this text editor. So, here is my job description more

What’s up? The Friday links (53)
2013-01-18 | in The Friday LinksGeographical Information Systems (GIS) are one of the most important tools in geosciences and can be helpful in almost every discipline. They are widely used not only in academia, but also in industry and administration. Obviously, it’s a good idea to know how to use these softwares. There are dozens, if not hundreds of different GIS versions available, but only few of them are freeware, like QGIS. Our colleague Riccardo Klinger from Digital Geography started a crowdsourcing initiative to get money for creating a free online video tutorial for everyone who wants to learn QGIS. If you like this idea, support him here at startnext.de. more
