Potsdam.
With a computer program from Germany, which has been originally developed for predicting tsunamis, the United Nations now waking internationally about nuclear tests.
“With pride we met the fact that the UN organization for monitoring the full nuclear test ban treaty in Vienna the GFZ software has selected for use on the national data centers “, the scientific director of the Geo Research Center (GFZ) in Potsdam, Reinhard Hüttl said.
After the tsunami disaster of 2004, the Potsdam researchers had worked for five years at the software SeisComP3. “That was actually a new development,” said the GFZ spokesman Franz Ossing. The program is to warning centers in the Indian Ocean in use. Before systems have a very long time for it to deliver data. But you must react quickly. The GFZ program can determine the time, place and magnitude of an earthquake with strong shocks in just a few minutes. Even during an event data would be delivered to the extent. “The evaluation at the end does not differ substantially from these data. SeisComP3 has loudly GFZ developed into a global standard.
In addition to this use in disaster response, the software tracks now in the service of the Nuclear Test Ban Authority among others underground tests. The software has been extended according GFZ 2015 for these purposes, so that it is from this year onward. Also GFZ sensors had thanks to the special technique on January 6 reported precise measurements at a station in Saxony-Anhalt eleven minutes after the explosion in North Korea. It was registered at the test site of Punggye Ri a quake with a magnitude of 5.3.
With a dense network of monitoring stations, the UN agency CTBTO monitored for nearly 20 years, the agreed Test Ban Treaty. The contract, however, is not yet formally entered into force because only 44 states must ratify it with nuclear technology. So far, there are only 41. Among others are still missing, the US, India and China.
