Water drainage from Kushiro Coal Mine decreased on the day of all M ≥ 7.5 earthquakes and increased thereafter

The amount of water drainage from Kushiro Coal Mine in Hokkaido, Japan decreased on the day of all M  ≥ 7.5 earthquakes with epicenters within 300 km of the mine during the monitoring period and increased after these earthquakes. This is a valuable finding which would give us a clue to understand pr...

Zusammenfassung:The amount of water drainage from Kushiro Coal Mine in Hokkaido, Japan decreased on the day of all M  ≥ 7.5 earthquakes with epicenters within 300 km of the mine during the monitoring period and increased after these earthquakes. This is a valuable finding which would give us a clue to understand pre- and post-seismic rockmass behaviors and contribute for progress in earthquake prediction in future.
