A translation, rotation, and infrasound array for Seismology
Since Jan 2011, thanks to the instrument support from IES and TEC, we have successfully completed the siting and installation of six
long‐term stations at the Nanao Park owned by the Forest Bureau
and its neighboring area. This array is unique in several ways:
(1) It is designed to monitor both translational and rotational
ground motions, (2) It quipped three infrasound sensors since
Jan. 2018, and (3) It was motivated to study earthquake swarms.
- Using array methods to study wavefield of earthquakes, infrasound and other events.
- Detailed mapping of earthquake swarm activities to test the Kanamori 1972 hypothesis that earthquake swarms are related to the occurrence of great earthquakes
