The “Tsunami Earthquake” of 13 April 1923 in Northern Kamchatka: Seismological and Hydrodynamic Investigations

  author={Amir Salaree and Emile A. Okal},
  journal={Pure and Applied Geophysics},
We present a seismological and hydrodynamic investigation of the earthquake of 13 April 1923 at Ust’-Kamchatsk, Northern Kamchatka, which generated a more powerful and damaging tsunami than the larger event of 03 February 1923, thus qualifying as a so-called “tsunami earthquake”. On the basis of modern relocations, we suggest that it took place outside the fault area of the mainshock, across the oblique Pacific-North America plate boundary, a model confirmed by a limited dataset of mantle waves…

We present a modern seismological study of the earthquake of 26 June 1941 in the Andaman Islands, the largest pre-2004 event along that section of the India-Burma plate boundary. Despite a large
Introduction to “Global Tsunami Science: Past and Future, Volume III”
AbstractTwenty papers on the study of tsunamis are included in Volume III of the PAGEOPH topical issue “Global Tsunami Science: Past and Future”. Volume I of this topical issue was published as
Effects of bathymetry complexity on tsunami propagation: a spherical harmonics approach
S U M M A R Y This paper explores the effects on tsunami simulations of the level of detail of the bathymetric grid in use. For this purpose, we expand available bathymetric data sets of the Pacific


The ‘tsunami earthquake’ of 1932 June 22 in Manzanillo, Mexico: seismological study and tsunami simulations
SUMMARY We conduct a detailed seismological study of the large Colima, Mexico earthquake of 1932 June 3 and of its aftershocks of June 18 and 22. The latter (Event III) generated a tsunami more
A seismological reassessment of the source of the 1946 Aleutian 'tsunami' earthquake
SUMMARY 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
Tsunami sedimentation associated with the 1923 Kamchatka earthquake
Abstract The Kuril-Kamchatka region is notorious for the occurrence of earthquake tsunamis, and historical documents show that they have caused repeatedly considerable damage since the 1750s. The
Mechanism of tsunami earthquakes
The mechanism of the Aleutian islands earthquake of 1946 and the Sanriku earthquake of 1896 is studied on the basis of the data on seismic waves from 5 to 100 s and on tsunamis. These earthquakes
The 1956 earthquake and tsunami in Amorgos, Greece
SUMMARY We conduct a comprehensive study of the Amorgos, Greece earthquake and tsunami of 1956 July 09, the largest such event in the Aegean Sea in the 20th century. Systematic relocation of the main
Motion of the Ugamak Slide, probable source of the tsunami of 1 April 1946
The eastern Aleutian tsunami of 1 April 1946 exhibited large waves and caused extensive damage throughout the eastern Pacific, yet the source region inferred from aftershocks was only 80 km wide.
Tsunami earthquakes and subduction processes near deep-sea trenches
A tsunami earthquake is defined as a shock which generates extensive tsunamis but relatively weak seismic waves. A comparative study is made for the two recent tsunami earthquakes, and a subduction
Use of the mantle magnitudeMm for the reassessment of the moment of historical earthquakes
The mantle magnitudeMm is used on a dataset of more than 180 wavetrains from 44 large shallow historical earthquakes to reassess their moments, which in many cases had been previously estimated only
Shallow subduction zone earthquakes and their tsunamigenic potential
SUMMARY We have examined the source spectra of all shallow subduction zone earthquakes from 1992 to 1996 with moment magnitude 7.0 or greater, as well as some other interesting events, in the period
T-wave duration, magnitudes and seismic moment of an earthquake—application to tsunami warning
We present a study of the duration, T, of T wave trains propagating over teleseismic distances in the ocean, and recorded at island stations, in relation to the various magnitudes (mb, Ms, Mw) of the
