Abstract

As a result of the October 17, 1989, Loma Prieta earthquake, liquefaction of the fluvial, estuarine, eolian, and beach sediments under a sand spit destroyed the Moss Landing Marine Laboratories and damaged other structures and utilities. Detailed offshore investigations indicate that liquefaction occurred over a large area (max. 8 km2) during or shortly after the earthquake with movement of unconsolidated sediment toward and into the head of Monterey submarine canyon. Many distinct lobate features were identified on the shallow shelf. These features almost certainly were the result of the October 17 earthquake; they were subsequently destroyed by winter storms. -from Authors
