German research team said, the satellite-based GPS position can offer detailed information on tsunami events within a few minutes after the earthquake occurred.
They believe that technology can fix the signal issues when the tsunami struck Japan in 2011.
The results of this study have been published in Natural Hazards and Earth Systems Sciences.

Shifting tectonic plates can produce a giant wall of water that can be advanced to the mainland in a minute, thus giving little time for evacuation.
