There are articles to read, videos to watch and positions to be found: paleoseismology of Chilean turbidites, lake sediments investigated near the North Anatolian Fault, indoor footage of the Gorkha Earthquake and a discussion on Elsevier’s new sharing policies. Today is Friday and here are your links!

Typhoon Haiyan was among the strongest storms ever recorded and likely the strongest one to make landfall in historical times. This mega storm hit the Philippines with windspeeds of more than 300 km/h. It caused thousands of fatalities, widespread flooding and devastation especially in its direct path. NASA’s Terra satellite is equipped with the ASTER sensor. This sensor is perfect for producing false color images of land cover and vegetation. In this image series it becomes clear that typhoon Haiyan destroyed a significant part of the vegetation around Tacloban. more

On 11 April 2012, a Mw8.6 strike-slip earthquake occurred off Sumatra in a kind of intra-plate setting and came as a surprise to the earthquake community. Such a strong strike-slip event was not expected, we always thought that the huge thrust quakes at subduction zones were the only ones to release that much energy. Now a press release by CalTech reports on the latest studies that came to the result that many previously unknown perpendicular faults ruptured at this event. Immediately some journalists suggested that this might also happen at the San Andreas Fault. I do not know of any paleoseismological evidence that this has happened there before. However, how likely is this scenario?
