far-field tsunami; distant tsunami
Technical term used in seismology and disaster prevention for a tsunami originating far from the affected coast, especially one generated outside Japan.
Because a far-field tsunami originates far away, it often takes time to arrive.
The Japan Meteorological Agency issued information about a distant tsunami.
Refers to a tsunami generated near the affected coast, in contrast to 遠地津波 which originates far away.
General term for tsunami; 遠地津波 specifies the distant-origin type.
Compound of 遠地 (えんち, 'distant place') and 津波 (つなみ, 'tsunami').
