From: Various far-field hydrological responses during 2015 Gorkha earthquake at two distant wells
Amplitude ratio (a) and phase response (b) of LJ well change with time at M2 wave frequency. Amplitude response is amplitude ratio of earth tide and water level. Dotted line shows the origin time of 2015 Gorkha earthquake (Beijing time). Blue error bars indicate the error of the tidal analysis. Bottom panels in figures a and b are the magnifications of the corresponding period of the gray background in the top panels, respectively
