High-Precision Seismicity Catalog for the 2022 Hunga Tonga-Hunga Ha-apai Volcanic Eruption This is a catalog of precise relocations of earthquakes surrounding the 2022 Hunga Tonga-Hunga Ha-apai Volcanic Eruption. These were generated using using surface-wave double-difference measurements, and relative magnitudes were computed between events. For details of the methodology used to produce this catalog, and the interpretation of these data, see the Seismological Research Letter publication "High-Precision Characterization of Seismicity from the 2022 Hunga Tonga-Hunga Ha-apai Volcanic Eruption". Locations use the WGS 1984 Datum. One comma-separated table is provided in this data release, relocations.csv, which is a summary of the relocation magnitude analysis. It includes 18 columns: Column 1 (time):... Categories: Data, Data Release - In Progress; Tags: GHSC, Golden, Tonga, USGS, earthquake, All tags... earthquake hazards, relocation, seismic, Fewer tags
