During this period, the Chilean earthquake of 1960 has the largest M s, 8.5. The surface-wave magnitudes listed in "Earthquake Data Reports" are found to be higher than M s on the average. By using the same method as that used by Gutenberg, the broad-band body-wave magnitudes m B ...
For that study the coefficient "b" in the magnitude versus frequency equation is 0.35 for the former and 0.76 for the latter. A similar investigation has been carried out on the great Chilean earthquake of 1960, also accompanied by many foreshocks and aftershocks. Using four sensitive and ...

Those stud- ies concluded that the 1700 Cascadia earthquake with a magnitude range of 8.7–9.2 ruptured the entire Cascadia subduction zone. An earthquake in Hokkaido in the seventeenth cen- tury (the seventeenth century Hokkaido earthquake) was a great prehistoric earthquake (Mw 8.8) in which ...
Megathrust earthquakes are responsible for some of the most devastating natural disasters1. To better understand the physical mechanisms of earthquake generation, subduction zones worldwide are continuously monitored with geophysical instrumentation. One
121, No. 1, 1983 Interpretation of the Precursor to the 1960 Great Chilean Earthquake as a Seismic Solitary Wave FERNANDO LUND 1 Abstract - Seismic solitary waves may exist. The situation envisaged is that of an elastic layer over a half space where transverse, linearly polarized surface waves...
At Pichilemu, in the northern third of the rupture area of the moment magnitude scale (Mw) 8.8 2010 Chile earthquake, deposits of the tsunami accompanying the earthquake consist of a lower layer of medium to fine sand (mean grain size of 200 μm) containing rock clasts, overlain by a...
The Mt scale is experimentally adjusted to the Mw scale introduced by Kanamori (1977), so that the Mt scale measures the seismic moment of a tsunamigenic earthquake as well as the overall size of tsunami at the source. Mt and the conventional tsunami magnitude m are distinct scales. By ...
Strain is released along the Chilean megathrust by great earthquakes, including the greatest magnitude ever recorded, the 1960 M9.5 rupture of the Valdivia segment. These earthquakes are characterised by intense, long duration shaking, significant land surface deformation and typically spawn trans-Pacific...
