Hydrospheric modulation of stress and seismicity on shallow faults in southern Alaska

CW Johnson, Y Fu, R Bürgmann - Earth and Planetary Science Letters, 2020 - Elsevier
Abstract Shallow (≤ 40 km), low magnitude (M≥ 2.0) seismicity in southern Alaska is
examined for seasonal variations during the annual hydrological cycle. The seismicity is …
