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.
Eldon Trinity The Eldon Trinity is a fireboat operated in Portland, Oregon by the Portland Fire Bureau. She was launched in 2010. She is named after two children, Eldon and Trinity Smith, whose mother threw them off a bridge into Portland's Williamette River. Authorities recognized that the attempts to rescue the children exposed weaknesses in the city's rescue infrastructure. Eldon died, while his older sister Trinity survived.
