Ground to Air Coupled Waves from a Distant Earthquake

Abstract

ON May 16, 1968, at 00 h 48 min 55 s, there was a strong earthquake off the east coast of Honshu, Japan. According to the US Coast and Geodetic Survey (USCGS) large tsunami tidal waves were set up which caused the loss of ninety-five vessels and reached a height of 4.5 m at Mikayo. On land, 18,500 houses were reported destroyed or damaged. Although the resultant casualties, forty-seven killed and 281 injured, were relatively light, the mean surface wave magnitude MS = 7.9 assigned to the earthquake by the USCGS classifies it as an important seismic event.
