Dataset of earthquakes in the northern Hikurangi subduction zone, New Zealand, during the 2019 slow slip event

※This catalog is part of the JGR paper, Iwasaki et al., 2025 (https://doi.org/10.1029/2025JB031751). Earthquake_catalog.csv: This file contains information of 964 events located in our main study area, with origin time (UTC time), latitude, longitude, depth, magnitude. Event_waveform.tgz: This archive contains waveforms of 964 events located in our main study area. Each waveform segment, named after the event origin time, spans from 5 seconds before the first picked phase arrival to 30 seconds after the last picked phase arrival and includes three-component recordings from the ocean bottom seismometer stations where the phases were identified. The waveform amplitudes are given in meters per second (m/s), and the instrumental response has not been removed. OBS_Instrumental_response.zp: The instrument response of the ocean bottom seismometers is described using pole-zero information. OBS_locations.txt: Geographic coordinates of the ocean bottom seismometers.
