A group of Japanese researchers has succeeded in detecting details of underground fault movements following a powerful earthquake in Hokkaido in September last year by using data collected by GPS, group members said Monday.

The group, including Shinichi Miyazaki, assistant lecturer at the Earthquake Research Institute of the University of Tokyo, and Kazuki Koketsu, a professor at the institute, succeeded in detecting the movements by analyzing the data on GPS which is able to detect lengthy quakes. A seismometer is unable to detect long quakes lasting more than one to two minutes, while GPS is good at doing so. (Kyodo News)
