Strongest in the United StatesThe Good Friday Earthquake which struck Alaska, USA on March 27, 1964 measured 9.2-magnitude on the Richter scale. Strongest in the 48 contiguous United StatesThe New Madrid Earthquake on February 7, 1812 is estimated to have measured 8.0 magnitude. Answer #2Actually the 1812 New Madrid Earthquake was measured 7.7 according to the USGS. Therefore, the strongest earthquake in the continental US was magnitude 7.9 on Jan 9, 1857 in Fort Tejon, California.
It was actually the 3rd largest earthquake of all time, measuring 9.1 The quake in Alaska in March 1964 measured 9.2 and the one in Chile in May 1960 measured 9.5
Not that has ever been recorded by man. The largest recorded earthquake occurred off the west coast of Chile in 1960 and had a magnitude of 9.5. It is thought that the impact that occurred 65.5 million years ago creating the Chixulub crater beneath the Yucatán Peninsula in Mexico (and thought to have contributed to the extinction of the dinosaurs) yielded energy equivalent to an earthquake of magnitude 12.5.
The Good Friday Earthquake on March 27, 1964 had its epicenter near Prince Wiliam Sound, Alaska. It lasted about 5 minutes, and caused 131 deaths, but it may not be true.This earthquake was the 4th most powerful earthquake ever recorded, and the most powerful earthquake to have an epicenter in the United States.
The top 10 largest death tolls in an earthquake by name and the number of fatalities are 1) Shaanxi with an estimated 820,000-830,000 deaths, 2) Haiyuan with 273,400 deaths, 3) Tangshan with 242,769 deaths, 4) Antioch with 240,000 deaths, 5) Indian Ocean with 230,210 deaths, 6) Aleppo with 230,000 deaths, 7) Haiti with an estimated 100,000 to 316,000 deaths, 8) Damghan with an estimated 200,000 deaths, 9) Ardabil with an estimated 150,000 deaths, and 10) Messina with 123,000 deaths.
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.

On Good Friday, March 27, 1964, the Great Alaska Earthquake did major damage. Across south-central Alaska, ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 139 deaths.

1875 was the stronger earthquake in ohio The Anna (Shelby County) earthquake on March 9, 1937 was the strongest earthquake to strike Ohio. Few seismographs were available at that time; however, based on the felt area of the earthquake and the damage that occurred in Anna and surrounding communities, the U.S. Geological Survey assigned a magnitude of 5.4 to this earthquake. This is from the ODNR Division of Geological Survey - OhioSeis Network
The epicenter of the earthquake was approximately 12.4 miles (20 km) north of Prince William Sound and 78 miles (120 km) east south east of Anchorage. It's exact location was 61 deg 3' 0'' N, 147 deg 28' 48'' W. Please see the related links.

Following the 9.0 magnitude earthquake there were 200+ earthquakes on March 11, 2011 with magnitudes between 3.9 and 7.9 according to USGS data.
The loudest recorded earthquake occurred in Japan in March of 2011. The Pacific Marine Environmental Laboratory and Oregon State University stated it was the loudest underwater sound ever recorded.
