Identification of infrasonic and seismic components of tremors in single-station records: application to the 2013 and 2018 events at an isolated volcanic island, Ioto, Japan
Abstract:Infrasonic stations are sparse at many volcanoes, especially those on remote islands and those with less frequent eruptions. When only a single infrasound station is available, the seismic-infrasonic cross-correlation method has been used to extract infrasound from wind noise. However, it does not work with intense seismicity and sometimes mistakes ground-to-atmosphere signals as infrasound. This paper proposes a complementary method to identify the seismic component and the infrasonic component using a single… Show more
