The mechanism of sandblowsBulletin of the Seismological Society of America - Tập 48 Số 2 - Trang 155-161 - 1958
George W. Housner
abstract
The formation of sandblows by earthquakes is explained in terms of well-known properties of water-bearing soils. The important parameters of the problem are the porosity, the permeability, the elasticity, and the degree of consolidation of the soil. The important conditions are that the water table be sufficiently near the ground surface and...... hiện toàn bộ
Macroseismic study of shallow earthquakes in the central and eastern parts of the trans-Mexican volcanic belt, MexicoBulletin of the Seismological Society of America - Tập 86 Số 6 - Trang 1952-1963 - 1996

Abstract
We present isoseismal maps for eight shallow earthquakes (1887 Pinal de Amoles, 1912 Acambay, 1920 Jalapa, 1950 Ixmiquilpan, 1976 Cardonal, 1979 Maravatío, 1987 Actopan, and 1989 Landa; 4.1 ≦ mb ≦ 6.9) that occurred in the central and eastern parts of the trans-Mexican volcanic belt. Based on their intensity distributions, we can relate seve...... hiện toàn bộ
Static stress changes and earthquake triggering during the 1954 Fairview Peak and Dixie Valley earthquakes, central NevadaBulletin of the Seismological Society of America - Tập 87 Số 3 - Trang 521-527 - 1997
S. John Caskey, Steven G. Wesnousky
AbstractThe 16 December 1954 Dixie Valley (MS 6.8) earthquake followed the Fairview Peak (MS 7.2) earthquake by only 4 min and 20 sec. A three-dimensional model of the two dip-slip fault systems based on recent detailed field studies shows the ruptures were separated by a 6-km step in surface trace. A boundary-element approach shows that the static stress changes i...... hiện toàn bộ
