San Francisco Earthquake And The 1964 Alaska

Alaska Standard Time a.

The epicenter of the earthquake was The focus occurred at a depth of approximately Ocean floor shifts created large tsunamis up to feet 67 m in heightwhich resulted in many of the deaths and much of the property damage. Vertical displacement of up to 38 feet Studies of ground motion have led to a peak ground acceleration estimate of 0.

The fault responsible was the Aleutian Megathrusta reverse fault caused by a compressional force. This caused much of the uneven ground which is the result of ground shifted to the opposite elevation. Tsunamis Calculated travel time map for the tectonic tsunami produced by the Prince William Sound earthquake in Alaska. Map does not show the height or strength of the waves, only the calculated travel times. Red: hour arrival times Yellow: hour arrival times Green: hour arrival times Blue: hour arrival times.

Two types of tsunamis were produced by this subduction zone earthquake. There was a tectonic tsunami produced in addition to about 20 smaller and local tsunamis.

These smaller tsunami were produced by submarine and subaerial landslides and were responsible for the majority of the tsunami damage. The largest tsunami wave was recorded in Shoup Bay, Alaska, with a height of about ft 67 m.

The ruin of Portage A 2x6 plank driven through a ten-ply tire by the tsunami in Whittier. As a result of the earthquake, people are believed to have died: [3] Fifteen died as a result of the earthquake itself, died from the subsequent tsunami in Alaska, [7] 5 died from the tsunami in Oregonand 13 died from the tsunami in California. The quake was a reported XI on the modified Mercalli Intensity scale "indicating major structural damage, and ground fissures and failures".

USGS video explaining the earthquake and footage Anchorage area Most damage occurred in Anchorage, 75 mi km northwest of the epicenter. Anchorage was not hit by tsunamis, but downtown Anchorage was heavily damaged, and parts of the city built on sandy bluffs overlying "Bootlegger Cove clay " near Cook Inlet, most notably the Turnagain neighborhood, suffered landslide damage. The neighborhood lost 75 houses in the landslide, and the destroyed area has since been turned into Earthquake Park. The Government Hill school suffered from the Government Hill landslide leaving it in two jagged, broken pieces. Land overlooking the Ship Creek valley near the Alaska Railroad yards also slid, destroying many acres of buildings and city blocks in downtown Anchorage.]

Anchorage area[ edit ] Most damage occurred in Anchorage, 75 mi km northwest of the epicenter. Anchorage was not hit by tsunamis, but downtown Anchorage was heavily damaged, and parts of the city built on sandy bluffs overlying " Bootlegger Cove clay " near Cook Inlet , most notably the Turnagain neighborhood, suffered landslide damage. The neighborhood lost 75 houses in the landslide, and the destroyed area has since been turned into Earthquake Park. Land overlooking the Ship Creek valley near the Alaska Railroad yards also slid, destroying many acres of buildings and city blocks in downtown Anchorage. Most other areas of the city were only moderately damaged. The foot 18 m concrete control tower at Anchorage International Airport was not engineered to withstand earthquake activity and collapsed, killing William George Taylor, the Federal Aviation Agency air traffic controller on duty in the tower cab at the time the earthquake began.
