Faster GPS predict tsunami

German researchers today quoted earthquake data in Japan last year, compared to the current alarm system, global positioning system (GPS) can provide more rapid tsunami warning.

Germany Earth Science Research Center (GFZ) in Potsdam (Potsdam) scientists Barbados Kou (Andrey Babeyko) statement: "Fukushima earthquake events, we analyzed over 500 GPS tracking stations and proposed seismic scale numerical 9, and after the earthquake, only 3-4 minutes to accurately predict the earthquake could trigger tsunami. "

He added, "once again shows the GPS has the potential tsunami early warning.

Scientists meeting in Vienna, the European Geosciences Union (EGU) for one week on the findings.

The researchers said that, near the coast of the earthquake, tsunami accompanied attacks on land in a short period after 20-30 minutes, but the GPS in the earthquake measured near-zero-day, so you can more quickly assess the seismic scale.

They pointed out that the traditional measurement methods require a long time to come to the correct data, and often underestimate earthquake scale outset.
