Vent of a sand volcano produced by liquefaction is about 4 feet across. The strip spanning the vent is a conduit for the drip irrigation system. The furrow spacing in the strawberry field is about 4 feet on center. Loma Prieta, California, Earthquake October 17, 1989. Watsonville area. Slide XIV-2, U.S. Geological Survey Open-File Report 90-547.

Damaged approach and abutment of the bridge linking the Moss Landing spit to the mainland near the Moss Landing Marine Laboratory. Liquefaction of the beach and Salinas River deposits caused ground cracking and differential settlement. Loma Prieta, California, Earthquake October 17, 1989. Moss Landing. Slide XV-2, U.S. Geological Survey Open-File Report 90-547.

Structural failure of the twin bridges carrying Highway 1 across Struve Slough. Loma Prieta, California, Earthquake October 17, 1989. Watsonville area. 1989. Slide XIV-11, U.S. Geological Survey Open-File Report 90-547.

Liquefaction in recent deposits of the Pajaro River formed these sand volcanoes along extensional fissures in a field near Pajaro prepared for autumn planting. Furrows are spaced about 1.2 meters (4 feet) apart. Loma Prieta, California, Earthquake October 17, 1989. Watsonville area. Slide XIV-1, U.S. Geological Survey Open-File Report 90-547.

Partially razed earthquake-damaged unreinforced masonry buildings in Old Town historical district. Salinas. Loma Prieta, California, Earthquake October 17, 1989. Slide XVI-1, U.S. Geological Survey Open-File Report 90-547.

Moss Landing. Liquefaction and subsequent strong tidal action destroyed the causeway carrying the Moss Beach access road across the tidewater basin. Loma Prieta, California, Earthquake October 17, 1989. Slide XV-1, U.S. Geological Survey Open-File Report 90-547.

Liquefaction in recent deposits of the Pajaro River formed sand volcanoes along a fissure 6 to 7 meters (19.7 to 23 feet) in length. The variation in grain size and the partial erosion of the conical deposits of sand show that the venting of the slurry of sand and water was a complex series of depositional and erosional events triggered by the main shock and renewed by principal aftershocks in some instances. Loma Prieta, California, Earthquake October 17, 1989. Watsonville area. Slide XIV-3, U.S. Geological Survey Open-File Report 90-547.

Sand volcano or "sand boil" measuring 2 meters (6.6 feet) in length erupted in the median of Interstate 80 west of the San Francisco-Oakland Bay Bridge toll plaza. Ground shaking transformed a loose water-saturated deposit of subsurface sand into a sand-water slurry (liquefaction). The vented sand contains marine shell fragments. Loma Prieta, California, Earthquake October 17, 1989. Slide II-3, U.S. Geological Survey Open-File Report 90-547.
