On which day in 1989 did this earthquake occur in which the fireboat "Phoenix" was instrumental in saving the Marina District buildings from further destruction?
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.
Phoenix (1845) The Phoenix was a steamship that burned on Lake Michigan on 21 November 1847, with the loss of at least 190 but perhaps as many as 250 lives. The loss of life made this disaster, in terms of loss of life from the sinking of a single vessel, the fourth-worst tragedy in the history of the Great Lakes.
