NIED Earthquake Mechanism Search

Search results are limited to 5,000 events. Monthly catalog files are available in the TEXT format.
We take coordinates (x, y, z) as (North, East, Down) for the moment tensor solutions.
*Number of events in NIED F-net catalog
2015: Approx. 1,400 events
2011: Approx. 6,900 events
