Ground shaking and engineering studies on the Parkfield section of the San Andreas fault zone

Earthquakes have been occurring in California for eons and will continue to play an important role in the evolution of California landforms. Recent California earthquakes have been of moderate size (magnitude 5.5 to less than 7), have occurred in rural or low population areas, and have therefore been important mainly to scientists and local citizens. Nevertheless, because of the loss that can result from ground shaking during an earthquake, experiments are now being planned for the Parkfield area that will improve the prediction to ground motion and the understanding of damage to small structures and pipelines.

Seismology program; California Division of Mines and Geology

The year 1980 marked the centennial of the California Division of Mines and Geology (CDMG) and a decade of the Division's involvement in seismology. Factors which contributed to the formation of a Seismology Group within CDMG included increased concerns for environmental and earthquake safety, interest in earthquake prediction, the 1971 San Fernando earthquake and the 1973 publication by CDMG of an urban geology master plan for California. Reasons to be concerned about California's earthquake problem are demonstrated by the accompanying table and the figures. Recent seismicity in California, the Southern California uplift reflecting changes in crustal strain, and other possible earthquake precursors have heightened concern among scientific and governmental groups about the possible occurrence of a major damaging earthquake )M>7) in California.

Earthquake predictions using seismic velocity ratios

Since the beginning of modern seismology, seismologists have contemplated predicting earthquakes. The usefulness of earthquake predictions to the reduction of human and economic losses and the value of long-range earthquake prediction to planning is obvious. Not as clear are the long-range economic and social impacts of earthquake prediction to a speicifc area. The general consensus of opinion among scientists and government officials, however, is that the quest of earthquake prediction is a worthwhile goal and should be prusued with a sense of urgency.
