There was a 9.2 magnitude earthquake in Prince William Sound, Alaska in 1964.
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.
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.
This is debatable, but the three worst earthquakes in the U.S. were likely the San Francisco earthquake of 1906, the Alaskan earthquake of 1964, and the New Madrid, Missouri earthquake, which was in the early 19th century.
Significantly fewer people died or were left homeless by last year's earthquake in Haiti than claimed by the country's leaders, a draft report commissioned by the US government has said. The unpublished report puts the death toll between 46,000 and 85,000. Haiti's government says about 316,000 died. It also suggests many of those still living in tent cities did not lose their homes in the disaster. Haitian authorities have stood by their figures released last year. The draft report, which has yet to be released publicly, is based on a survey commissioned by the US Agency for International Development (USAID) and draws its numbers from door-to-door surveys carried out over 29 days in January 2011.

The biggest earthquake ever recorded, which occurred near the cities of Valdivia and Puerto Montt, Chile, in 1960. Known as the Great Chilean Earthquake, the quake measured an impressive 9.5 on the Richter scale. The death toll of the Great Chilean Earthquake is not known, although the USGS estimates about 1,655 people died, and the earthquake may have caused as much as $800 billion US Dollars in damage.
