A megathrust earthquake genesis process observed by a Global Positioning System
Fumihide Takeda
TL;DR
This paper discusses how GPS observations in Japan captured the 2011 Tohoku megathrust earthquake process over fifteen months, indicating potential for real-time earthquake prediction.
Contribution
It presents the first detailed GPS-based observation of the entire genesis process of a major megathrust earthquake.
Findings
GPS data revealed the gradual buildup of strain before the earthquake
The observed process suggests potential for real-time earthquake prediction
The study provides new insights into earthquake genesis mechanisms
Abstract
Japan's GPS observed the fifteen-month megathrust earthquake genesis process of the 2011 Tohoku M9, suggesting the real-time predictability of such events.
