原始语种摘要: Characteristics and statistics of seismic tremors occurring during April 2015were investigated by using short-period and broadband seismographs deployedat Syowa Station (SYO), in the Lützow-Holm Bay (LHB), East Antarctica.In order to examine a relationship between surface environments in particularcryosphere variation, the MODIS satellite images were utilized forcomparison with the detected tremor events. Since a large volume of sea-icewas discharged during the April, together with several large icebergs passedthrough from the west to the east at northern edge of the fast sea-ice of LHB,it was expected to detect seismic tremors involving cryospehre dynamics.During the month, a total number of 49 tremor events including short durationice shocks were identified. Majority of the events (N =...
