The Zihuatanejo, Mexico, earthquake of 1994 December 10 (M= 6.6): source characteristics and tectonic implications

Howard M. Temin (10 December 1934-9 February 1994).

Source process and tectonic implications of the great 1975 North Atlantic earthquake

The Atlantic segment of the Africa-Europe plate boundary has usually been interpreted as a transform boundary on the basis of the bathymetric expression of the Gloria fault and dextral strike-slip first-motion mechanisms aligned along the Azores-Gibraltar line of seismicity. The 1975 May 26 earthquake (Ms=7.9) was assumed to fit into this framework because it occurred in the general area of thi...

The SanrikuOki, Japan, Earthquake of December 28, 1994 Mw 7.7 Rupture of a different asperity from a previous earthquake

Fault geometry, depth, and slip distribution of the Sanriku-oki earthquake of December 28, 1994 (Ms 7.5) are estimated from seismic waveforms, geodetic measurements, and tsunami waveforms, and compared with those of the 1968 Tokachi-oki earthquake (Mw 8.2), the most recent large earthquake in the epicentral region. Seismic wave inversions indicate a shallowly dipping thrust type mechanism and t...

Tectonic Background of the Wenchuan Earthquake

Rapid Assessment of Earthquake Source Characteristics

Recent studies emphasize the rapid assessment of earthquake source properties, such as moment magnitude, to help alleviate the impact of earthquakes. Depending on local crustal structure, earthquakes occurring at different depths can differ greatly in high-frequency motions, which emphasizes the importance in constraining focal depth for the predictions of strong motions. For large earthquakes,...
