Today is Friday and here are your links on human-caused earthquakes, induced aseismic slip, typesetting costs, flash flood video footage, and more!

Two articles dealing with induced (or triggered?) seismicity caught my attention last week. Time came up with a report about “The Seismic Link Between Fracking and Earthquakes“. New studies on that topic had been presented at the SSA annual meeting in Alaska. Basically it’s now possible to link two phenomena: a) The huge increase in shale gas and oil development in Ohio, Oklahoma, and Kansas during the last few years; and b) the huge increase in earthquake activity in Ohio, Oklahoma, and Kansas during the last few years. more

Did you think there was no earthquake hazard in Central Europe? Don’t worry unless you live in Italy, Greece, or Turkey? Wrong! There’s significant hazard not only in W Germany, S Spain and on the Balkan Peninsula – take into account mining induced events, too…

An earthquake of magnitude 4.6 occurred in SW Poland last night in very shallow depth. 19 copper miners were trapped inside the mine for hours after a tunnel collapsed and communication was cut. All miners were rescued, one suffered minor injuries.

The area is known as the Lubin mining area (coal and copper) and one of the hot spots in Central Europe’s seismicity. 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…
