It's all in a powerpoint presentation - lots of pictures - I don't have a map with the quake pinpointed, but probably could do that now with google earth.. here's the data on it: March 10, 1933 5:54 PM, PST Magnitude 6.4Mw LOCATION: 33° 37' N, 117° 58' W 5 km (3 miles) south of present-day Huntington Beach Focal mechanism: Right lateral Strike Slip Depth: 13km No evidence of surface faulting Rupture distance 13-16km Average slip: 85-120 cm Elevation change: 12-18cm Damages: 120 Deaths - greatest death toll of any historical southern California earthquake $50 million damage (1933 figures) Schools damaged most Building codes changed due to this quake: Statewide seismic design and construction requirements were mandated for public schools What is kinda the more interesting part of the presentation is what would happen now if it were to have a repeat.. Damage estimates if there is a repeat of the 1933 quake (a 6.5-7.4): Buildings $75,000,000,000 Casualties: 20,000-27,000 deaths and injuries Damage from fire: $2.5 Billion Hospital functionality one day after quake: 35% Fire Station functionality: 30% School functionality: 29% Displaced households: 137,515 Damaging aftershocks for about 1 month 405, PCH and other Long Beach roads damaged from liquefaction. 110 Freeway possible emergency access route. 130 miles of high traffic roads damaged 350 bridges damaged Airports out of service – liquefaction, towers down, no access, fuel tank damage Harbors and ports facilities damaged, seiches Numerous fires in streets and houses Fires rage for several days at the refineries in Carson-Wilmington area Emergency phone service: 25% day 1, 75% day 3, normal use significantly lower. Power plants shut down for at least 3 days. San Onofre has no damage Water lines broken – repaired within a week for most areas. Waste treatment plants at 50% capacity Main waste water line into Carson treatment plant from Long Beach heavily damaged. Lack of fresh water and electricity cause sewage spills into soils and streets contaminating groundwater and the coastline. Thousands of damaged natural gas mains, valves and service connections Many fuel lines rupture. Fuel lines to power plants rupture. Fuel spills and toxic emissions. Worse quake than the Big One on the San Andreas Fault... Maybe that's why I'm just a bit nrevous - one cat was finally getting back to normal and now he's hiding in a corner of his house.. Canie
