What the record says
NCEI’s account, from the sources it cites.
Abnormal volcanic earthquakes occurring near the volcanic island of Torishima, south of Japan, sometimes generate relatively larger tsunamis compared to the seismic magnitudes. They have seismic magnitude of M~6 but generate large tsunamis characterizing them as “tsunami earthquakes”. (reference #12653)
