Table 1: Dates and seismic stations at which earthquakes occurred. Table 1 outlines the date and time of occurrence, the geographic coordinates of the 15 Kumamoto and 9 Pohang earthquake epicenters, and the station names where ground motions were recorded. We processed 351 ambient noise recordings (comprising two horizontal and one vertical component) with 5% cosine tapering.
