There was a 9.2 magnitude earthquake in Prince William Sound, Alaska in 1964.
The worst US earthquake in terms of impact on people was probably the 1906 San Francisco Earthquake which is estimated to have led to the deaths of over 3,000 people and to have left between 227,000 and 300,000 people homeless out of a population of 410,000. In terms of magnitude, the worst earthquake in recorded US history was the 1964 Alaska earthquake which had a moment magnitude of 9.2. This makes it the most powerful earthquake recorded in the US and Canada and the second most powerful earthquake recorded on Earth by seismometer.
The largest recorded earthquakes in US are listed at this website: http://earthquake.usgs.gov/regional/states/10_largest_us.php. None of the ones listed on that list were in LA, but the Tejon earthquake, which was 7.9, was not too far away from LA. According to this website, the 1994 Northridge earthquake was the largest one (on the timeline) to hit Los Angeles. http://www.google.com/search?q=los+angeles+earthquake+history&hl=en&tbs=tl:1&tbo=1&ei=mVoTSsDaEYyq8gSs_Mz_Aw&sa=X&oi=timeline_result&ct=title&resnum=13 The Northridge earthquake was a 6.7 magnitude earthquake with high ground intensity. http://www.data.scec.org/chrono_index/northreq.html The Long Beach earthquake of 1933 was a 6.4 magnitude earthquake.
The 1964 Alaska earthquake (March 27, 1964) had its epicentre in Prince William Sound near Anchorage. The earthquake had a magnitude of 9.2 making it the largest ever to occur in the US, and the 3rd largest ever recorded by seismometer.
A tsunami is caused by an earthquake, which means that the earthquake would make the Earthquake list. Whether the list would include information on the created tsunami is unknown. Magnitude doesn't always correlate directly to the magnitude of the earthquake nor does it have a direct relationship with the number of deaths or the amount of destruction caused.The highest magnitude Earthquake was recorded in Chile in 1960 with a Magnitude of 9.5. ThisEarthquake created a tsunami that was initially 82 feet high, diminished to 35 feet when it hit the island of Hilo and only 15 feet when it reached Japan.The 2nd worst recorded Earthquake occurred December 26th, 2004 Earthquake Magnitude 9.1-9.3.This quake created 5 tsunamis.The largest/tallest recorded tsunami was created by a magnitude 7.9 earthquake that generated a wave 1720 feet high.
The 1989 earthquake in San Francisco, also known as the Loma Prieta earthquake, had a magnitude of 6.9 on the Richter scale. It caused significant damage and loss of life in the San Francisco Bay Area.
In Chile on the 22 May 1960. The city of Valdivia was the worst effected. Please see the related link for more information

According to the US Geological Survey the Haitian earthquake that occurred on the 12th of January 2010 had a magnitude of 7.0 on the moment magnitude scale. Please see the related links below.
well think about the earthquake in haiti it was really bad and also if it's a 8.9 out of 10 that's REALLY REALLY strong...so um yeah it was like a huge wall of water coming over the cities and messing up with the electrical stuff and blowing up up the power plant and causing major explosions

Alaska has experienced several major earthquakes with a magnitude of 7.0 or greater in the last 200 years. Notably, the 1964 Alaska earthquake, also known as the Great Alaska earthquake, had a magnitude of 9.2 and is the second most powerful earthquake ever recorded.
