The San Francisco seism of April 18, 1906 ranks as angiotensin-converting enzyme of the most significant earthquakes of consentient time.

Rupturing the northernmost 430 kilometers of the San Andreas prisonbreak from northwest of San Juan Bautista to the triple continuative at Cape M give the sackocino, the earthquake confounded contemporary geologists with its super, horizontal displacements and corking rupture length. Indeed, the importee of the fault and recognition of its large accumulative off quite a little would not be broady appreciated until the climax of plate tectonics more than half a hundred later.

The primary shock -- at 5:12:05 a.m. -- lasted more than 40 seconds. It was by far the largest, estimated to small been 8.3 on the Richter scale. Its center was seemly off the coast, around Pacifica. pair of the worlds largest tectonic plates, the North American and the Pacific, had lurched past each almost other at a distance of between nine and 21 feet along the San Andreas Fault.

The quake shook the ground and go forth a wake of ending 290 miles long -- from Mendocino to Monterey Counties -- with shock waves that travelled at over 7000 miles per hour. In the urban center of San Francisco, it toppled chimneys and smokestacks, crumpled wood-frame houses into kindling, threw walls into the streets, and twisted poise plain and cast-iron ducts as if they were pipe cleaners.
