1989 Loma Prieta earthquake The 1989 Loma Prieta earthquake occurred in Northern California on October 17 at local time. The shock was centered in The Forest of Nisene Marks State Park approximately 10 mi northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains. With a moment magnitude of 6.9 and a maximum Mercalli intensity of IX ("Violent"), the shock was responsible for 63 deaths and 3,757 injuries. The Loma Prieta segment of the San Andreas Fault System had been relatively inactive since the 1906 San Francisco earthquake (to the degree that it was designated a seismic gap) until two moderate foreshocks occurred in June 1988 and again in August 1989.
Drillship Seacrest DS Seacrest, also known as "the Scan Queen", is a drill ship built by Far East Levingston Shipbuilding Ltd., Singapore, owned by Unocal Corporation and operated by Great Eastern Drilling and Engineering company. It was sunk by Typhoon Gay in the Gulf of Thailand on 3 November 1989. Ninety-one rig workers were killed after the vessel capsized, resulting in a massive legal case brought against the ship's owners UNOCAL. There were only six reported survivors: one Indonesian diver and five Thai rig crew, although these figures vary slightly depending on the source. Many of the bodies were never recovered. Typhoon Gay produced winds of 100 knots or more with 40 feet waves. It left hundreds of sunken fishing vessels in its wake, killing 529 people and leaving approximately 160,000 homeless.
