 note = {Characteristics of non-tectonic tremors, excited mainly by the interaction within the cryosphere, were investigated using seismic waveform data of 2013–2015 recorded at broadband stations on the east coast of the Lützow-Holm Bay (LHB), East Antarctica. The tremors were classified into three types by spectral and waveform features. Type A events have long durations, typically several hours to days, with high amplitudes of spectra over 1–8 Hz. They occur dominantly in austral summers. Type B events have characteristically irregular variations in discrete dominant frequencies in spectra. Type C events are harmonic tremors with discrete dominant frequencies in spectra that vary regularly with time. Type B and C events show similar seasonal variations: they are numerous around April and less so in austral winter. Comparison of spectra between seismic waves and infrasound, together with satellite images, suggests that type A events originated from storm-induced swells near off-LHB. Source locations of type C events and satellite images suggest that type C events are likely to result from the collision/crevassing of ice blocks in fast-sea-ice in LHB. Similar seasonal variations of type B and C events imply that these two events have similar origins., Embargo Period 24 months, 金沢大学理工研究域地球社会基盤学系},
