Detailed analysis of tsunami waveforms generated by the 1946 Aleutian tsunami earthquake
The 1946 Aleutian earthquake was a typical tsunami earthquake which generated abnormally larger tsunami than expected from its seismic waves. Previously, Johnson and Satake (1997) estimated the fault model of this earthquake using the tsunami waveforms observed at tide gauges. However, they did not model the second pulse of the tsunami at Honolulu although that was much larger than the first pu...
متن کاملA long source area of the 1906 Colombia–Ecuador earthquake estimated from observed tsunami waveforms
The 1906 Colombia–Ecuador earthquake induced both strong seismic motions and a tsunami, the most destruc‐ tive earthquake in the history of the Colombia–Ecuador subduction zone. The tsunami propagated across the Pacific Ocean, and its waveforms were observed at tide gauge stations in countries including Panama, Japan, and the USA. This study conducted slip inverse analysis for the 1906 earthqua...
متن کاملA seismological reassessment of the source of the 1946 Aleutian ‘tsunami’ earthquake
S U M M A R Y We present a re-evaluation of the seismological properties of the Aleutian ‘tsunami earthquake’ of 1946 April 1, characterized by a deceptively low conventional magnitude (7.4) in view of its catastrophic tsunami, both in the near and far fields. Relocation of 40 aftershocks show that the fault zone extends a minimum of 181 km along the Aleutian trench, in a geometry requiring a b...
متن کاملFault parameters of the 1896 Sanriku Tsunami Earthquake estimated from Tsunami Numerical Modeling
The June 15, 1896 Sanriku earthquake generated devastating tsunamis with the maximum run-up of 25 m and caused the worst tsunami disaster in the history of Japan, despite its moderate surface wave magnitude (Ms=7.2) and weak seismic intensity. This is a typical tsunami earthquake, which generates anomalously larger tsunamis than expected from its seismic waves. Previously proposed mechanisms of...
متن کاملThe source of the 1722 Algarve earthquake: evidence from MCS and Tsunami data
The 27 December 1722 Algarve earthquake destroyed a large area in southern Portugal generating a local tsunami that inundated the shallow areas of Tavira. It is unclear whether its source was located onshore or offshore and, in any case, what was the tectonic source responsible for the event. We analyze available historical information concerning macroseismicity and the tsunami to discuss the m...
