In the Studio: Prof. Danijel Schorlemmer, Seismologist

Deutsche Welle (Mar. 21, 2011) Prof. Schorlemmer from the German Research Centre for Geosciences, GFZ, in Potsdam is an expert in the area of earthquake forecasting.DW-TV: Japan is a society that has played a pioneering role in a wide number of technologies -- including of course earthquake warning systems. But even then, people have just five seconds after the warning comes to brace themselves. Cutting straight to the chase, thousands of detection stations around the world, international networks, decades of research -- why can't we predict earthquakes yet? Danijel Schorlemmer: Well, even though we have thousands of stations, we have a big problem. We only measure the signals on the earth’s surface. Unlike in meteorology, where you can measure all the values you’re interested in, like humidity, wind-speed and so on in 3-D, we only see the earth’s surface.

At the same time, the European Union says clean water is a human right, and member states must take action to ensure it. But both local governments and national leaders in Hungary are ignoring the problem.
