Deep Tectonic Tremor Catalog in Nankai Trough from 2004.4 to 2023.12

This is a catalog of deep tectonic tremors in the Nankai Trough from April 2004 to December 2023 (Yano, Ide, and Nomura, submitted to JGR). Detection methodology is described in Mizuno & Ide (2019) and Yano & Ide (2024). *After detecting events using the method of Yano and Ide (2024), only those occurring at depths between 15 and 50 km were retained in the catalog Columns: year, month, day, hour, minute, second : date and time of the maximum amplitude of envelope waveform lat [deg], lon [deg], dep [km] : hypocentral location mag : magnitude based on seismic energy (Equation 16 in Mizuno & Ide, 2019) cc : cross-correlation (Equation 13 in Mizuno & Ide, 2019) x error [km], y error [km], z error [km] : uncertanties of hypocentral location energy dur [s] : event duration based on seismic energy rate (Section 2.2, Text S2, and Figure S1 in Yano & Ide, 2024) *Please cite the following articles if you use this catalog: 1.
