abstract Five microearthquake instruments were operated for 2 months in 1974 in a small mobile array deployed at various sites near the Agua Blanca and San Miguel faults. An 80-km-long dection of the San Miguel fault zone is presently active seismically, producing the vast majority of recorded earthquakes. Very low activity was recorded on the Agua Blanca fault. Events were also located near normal faults forming the eastern edge of the Sierra Juarez suggesting that these faults are active. Hypocenters on the San Miguel fault range in depth from 0 to 20 km although two-thirds are in the upper 10 km. A composite focal mechanism showing a mixture of right-lateral and dip slip, east side up, is similar to a solution obtained for the 1956 San Miguel earthquake which proved consistent with observed surface deformation.

The rural Kumiai community of San Antonio Necua is one of the few remaining indigenous communities in Baja California, Mexico. Necuan health and health care problems are best understood through a consideration of the effects of colonialism and marginalization on indigenous groups in northern Baja California as well as a tradition of medical pluralism in Mexico. The lack of traditional healers and biomedical providers in the community, high rates of preventable or manageable illnesses, and a blend of biomedical, folk mestizo, and traditional indigenous beliefs about health and illness reflect current conditions of rural poverty and economic isolation. Descriptions of health and health care problems are based on ethnographic fieldwork among the Kumiai, their Paipai relatives, and their primary nongovernmental aid organization.
