A: March 27 1964, Prince William Sound Alaska. 9.2
2. The largest earthquake in the Contiguous US history.
A: New Madrid. 1811 - 1812, 7.9
Facts:A series of earthquakes hit the New Madrid seismic zone of southeastern Missouri, northeastern Arkansas, and adjacent parts of Tennessee and Kentucky, in December 1811 to February 1812. Three earthquakes had a magnitude of 7.0 or greater. The first earthquake 7.7 occurred December 16, 1811, at 2:15 a.m.; the second 7.7 at 9 a.m. on January 23, 1812; and the third 7.9 -8.0 on February 7, 1812, at 3:45 a.m. These three earthquakes were among the largest to strike North America since European settlement.
The main shocks were followed by many hundreds of aftershocks that lasted for decades. Many of the aftershocks were major earthquakes themselves. The area that was strongly shaken by the three main shocks was 2--3 times as large as the strongly shaken area of the 1964 M9.2 Alaskan earthquake, and 10 times as large as that of the 1906 M7.8 San Francisco earthquake.

How powerful was the Earthquake in Chile?
The most recent Chilean earthquake mainshock occurred on the 27th of February 2010 and according to the US Geological Survey, rated at 8.8 on the moment magnitude scale. Chile has also suffered earthquakes in the past, including the largest earthquake ever recorded by seismometer which occurred on the 22nd of May, 1960 and had a magnitude of 9.5.
How many tsunamis have made the US worst earth quake list?
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.

What was the worst earthquake that has happened to the US?
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.
