Application of quantitative micropaleontologic methods of sea-surface temperature (SST) estimation to the planktic foraminiferal faunas at Hole 548 in the northeast Atlantic between 3.5 and 2.0 Ma provide a detailed record of Pliocene surface temperature changes during the onset of major Northern Hemisphere glaciation. SST estimates indicate a relatively warm...
Change in failure stress on the southern San Andreas fault system caused by the 1992 magnitude = 7.4 Landers earthquake
R.S. Stein, G.C.P. King, J. Lin
1992, Science (258) 1328-1332
The 28 June Landers earthquake brought the San Andreas fault significantly closer to failure near San Bernardino, a site that has not sustained a large shock since 1812. Stress also increased on the San Jacinto fault near San Bernardino and on the San Andreas fault southeast of Palm Springs. Unless...
Changes in static stress on southern California faults after the 1992 Landers earthquake
R.A. Harris, R.W. Simpson
1992, Nature (360) 251-254
The magnitude 7.5 Landers earthquake of 28 June 1992 was the largest earthquake to strike California in 40 years. The slip that occurs in such an earthquake would be expected to induce large changes in the static stress on neighbouring faults; these changes in stress should in turn affect the...

1992, Science (258) 1133-1135
The Middle Pliocene (∼3 million years ago) has been identified as the last time the Earth was significantly warmer than it was during the Last Interglacial and Holocene. A quantitative micropaleontological paleotemperature transect from equator to high latitudes in the North Atlantic indicates that Middle Pliocene warmth involved increased meridional...
A prediction of Mars seismicity from surface faulting
M.P. Golombek, W.B. Banerdt, Kenneth L. Tanaka, D.M. Tralli
1992, Science (258) 979-981
The shallow seismicity of Mars has been estimated by measurement of the total slip on faults visible on the surface of the planet throughout geologic time. Seismicity was calibrated with estimates based on surface structures on the moon and measured lunar seismicity that includes the entire seismogenic lithosphere. Results indicate...

New links between the Chicxulub impact structure and the Cretaceous/Tertiary boundary
Virgil L. Sharpton, G. B. Dalrymple, L.E. Marin, G. Ryder, B.C. Schuraytz, J. Urrutia-Fucugauchi
1992, Nature (359) 819-821
The 200-km-diameter Chicxulub structure1–3 in northern Yucatan, Mexico has emerged as the prime candidate for the Cretaceous/Tertiary (K/T) boundary impact crater3–6. Concentric geophysical anomalies associated with enigmatic occurrences of Upper Cretaceous breccias and andesitic rocks led Penfield and Camargo1 to suspect that this structure was a buried impact basin. More recently, the...
