RESEARCH
 

The research activities cover various fields of seismology of global-to-local, great-to-small earthquakes towards a quantification of seismic
activity of the world. Topics of current interest include observational studies of earthquake magnitude and revision of the catalog of world
earthquakes; studies of earthquake mechanism from waveform analysis; computational simulation of tsunami generation and propagation;
quantification of tsunami source size and estimates of tsunami heights before arrival; studies of waveform similarity among foreshocks and
aftershocks; studies of hypocenter determination procedure; studies of the integration of real-time earthquake data; research surveys of
earthquake disasters in the world; instrumental re-evaluation of old earthquakes around the turn of the century; studies on the temporal
variation of swarm earthquake activity. An active effort is being made to operate broadband and wide-dynamic-range seismographs and
analyze their seismograms.
