The Alaska earthquake of 1964 had a magnitude of 9.2, compared with the 1906 SF earthquake's magnitude of 7.8.
A 9.2 earthquake releases approximately 500 billion times the energy of a magnitude 7.8.
On April 18, 1906, At almost precisely 5:12 a.m., local time, a foreshock occurred with sufficient force to be felt widely throughout the San Francisco Bay area. The great earthquake broke loose some 20 to 25 seconds later, with an epicenter near San Francisco. Violent shocks punctuated the strong shaking which lasted some 45 to 60 seconds. The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada. Rupturing the northernmost 296 miles (477 kilometers) of the San Andreas fault from northwest of San Juan Bautista to the triple junction at Cape Mendocino, the earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length.The main shock of the San Francisco earthquake of 1906 lasted for approximately 45- 60 seconds.
An earthquake is called an earthquake no matter whether it is small or large. An earth tremor is just a general term used by people to describe a small earthquake.
A large crack in the Earth, formed by a river or an earthquake, would be called a canyon, such as the Grand Canyon, formed by the Colorado River. A smaller crack might be called a fissure.
a tsunami is a tidal wave caused by an underwater earthquake :]
A tsunami can happen if a large volume of water is suddenly displaced by an undersea earthquake.
Yes, it could. This phenomenon was observed before the Alaskan earthquake of 1964. It can happen as a result of the lake basin tilting prior to the quake.
No. The second highest earthquake magnitude (depending on the source of the information) was either the Boxing Day 2004 Indian Ocean earthquake (magnitude 9.1 - 9.3) or the 1964 Alaskan earthquake (magnitude 9.2). The Haitian Earthquake in January 2010 had a Richter magnitude of 7.2.
San Francisco needs earthquake proof buildings because in California theres a large fault line called the San Andreas fault line. It is along this fault line that lots of earthquakes occur.
Many have done so in the past, many will in the future. Any large earthquake in the Pacific will probably generate one that reaches San Francisco. However obviously none since the city was established has produced large enough waves to do damage, because the further away the earthquake the more the wave attenuates. The 1964 Anchorage, AK earthquake produced waves at San Francisco 2 to 3 feet tall. The 2011 Japanese earthquake produced waves at San Francisco under a foot tall. If you wanted a numerical answer, that is likely impossible to give as it depends on too many unknown variables.
the earthquake began and sent wind and debris everywhere, when the wind and debris was mixed with wood and winds hard enough to create fire. the fire was large and it mixed with the earthquake, created one of the biggest natural disasters in our countries history. that's all :) @rose@

It means that the earthquake is large and powerful.
An Alaskan malamute is part of thespecies of domesticated dog (Canis lupus familiaris).It is a large working spitz type dog.
No, the recent large earthquake of 9.0 was off the coast of Japan along with many hundreds of aftershocks since the initial very large earthquake.

If its a large earthquake, you can expect a tsunami to follow
No. There are hundreds. It is very large and spans most of the state. The cause of the most recent San Francisco area earthquake was in fact the Hayward Fault.
