Landslide: La Jolla, CA - October 3, 2007

(03/11/07)

• The 15 meter-wide-slide (50 yards) happened on Wednesday morning, October 3rd. • It was caused by the instability of the hillside slopes, • Not excessive water from rain or a broken water main, and • Not ground shaking from an earthquake. • The area was known to be geologically unstable and landslide prone as the result of a geologically old earthquake. • Landslides had occurred in 1961 during construction of the homes and again in 1989 and 1994 • City officials had issued a warning two weeks before and again on Tuesday night before the slide occurred on Wednesday.    Click here to download a PowerPoint Presentation with more details on this Event
