TY - JOUR PY - 2013// TI - Application of collocated GPS and seismic sensors to earthquake monitoring and early warning JO - Sensors (Basel) A1 - Li, Xingxing A1 - Zhang, Xiaohong A1 - Guo, Bofeng SP - 14261 EP - 14276 VL - 13 IS - 11 N2 - We explore the use of collocated GPS and seismic sensors for earthquake monitoring and early warning. The GPS and seismic data collected during the 2011 Tohoku-Oki (Japan) and the 2010 El Mayor-Cucapah (Mexico) earthquakes are analyzed by using a tightly-coupled integration. The performance of the integrated results is validated by both time and frequency domain analysis. We detect the P-wave arrival and observe small-scale features of the movement from the integrated results and locate the epicenter. Meanwhile, permanent offsets are extracted from the integrated displacements highly accurately and used for reliable fault slip inversion and magnitude estimation.
