The presentation focuses on the surviving Mexican families of the 1928 St. Francis Dam Flood disaster. The St. Francis Dam disaster is considered the second worst man-made disaster in California history and one of the worst civil engineering catastrophes in American history. This disaster killed over 450 individuals who lived along the Santa Clara River with many bodies never recovered because they were washed out to the Pacific Ocean. Many stories of survival have been documented in newspapers, article and books, but few have focused on Mexican family survivors. Using Spanish language newspapers and oral history interviews, Alamillo shows how Mexican family survival stories have been used as a form of activism to make visible their resilience and demands for environmental justice.
