1906 San Francisco earthquake

https://en.wikipedia.org/wiki/1906_San_Francisco_earthquake

The 1906 San Francisco earthquake struck the coast of Northern California at 5:12 a.m. on Wednesday, April 18 with an estimated moment magnitude of 7.9 and a maximum Mercalli intensity of XI (Extreme). High intensity shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in the city and lasted for several days. Thousands of homes were dismantled. As a result, up to 3,000 people died and over 80% of the city of San Francisco was destroyed. The events are remembered as one of the worst and deadliest earthquakes in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high in the

New Madrid Seismic Zone: Why The Middle Of The U.S. Could Be Hit By A HUGE Earthquake

https://en.wikipedia.org/wiki/New_Madrid_Seismic_Zone

The New Madrid Seismic Zone (/ˈmædrɪd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.

The New Madrid fault system was responsible for the 1811–12 New Madrid earthquakes, and has the potential to produce large earthquakes in the future. Since 1812, frequent smaller earthquakes have been recorded in the area.^[1]

Earthquakes that occur in the New Madrid Seismic Zone potentially threaten parts of eight American states: Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee, Oklahoma, and Mississippi.^[2]

• December 16, 1811, 0815 UTC (2:15 am); (M about 7.5)^[9] epicenter in northeast Arkansas, probably on the Cottonwood Grove fault;^{[10]:p. 7} it caused only slight damage to man-made structures, mainly because of the sparse population in the epicentral area. The future location of Memphis, Tennessee, was shaken at Mercalli level-nine intensity. A seismic seiche propagated upriver and Little Prairie was destroyed by liquefaction.^[11] Local uplifts of the ground and the sight of water waves moving upstream gave observers the impression that the Mississippi River was flowing backwards.^[12]

At New Madrid, trees were knocked down and riverbanks collapsed. This event shook windows and furniture in Washington, DC, rang bells in Richmond, Virginia, sloshed well water and shook houses in Charleston, South Carolina, and knocked plaster off of houses in Columbia, South Carolina. In Jefferson, Indiana, furniture moved, and in Lebanon, Ohio, residents fled their homes. Observers in Herculaneum, Missouri, called it "severe" and said it had a duration of 10–12 minutes.^[13]

Aftershocks were felt every 6-10 minutes, a total of 27, in New Madrid until what was called the Daylight Shock, which was of the same intensity as the first. Many of these were also felt throughout the eastern US, though with less intensity than the initial earthquake.^[13]

• December 16, 1811, sometimes termed the "Dawn Shock" or "Daylight Shock", occurred at 1315 UTC (7:15 am); (M about 7) with the epicenter in northeast Arkansas.^[9]

Earthquakes in the New Madrid and Wabash Valley seismic zones

As chief meteorologist for WEHT-TV in Evansville, IN, I spent much of 1990 doing speaking engagements to talk about earthquakes and not weather!

You can see how close that Evansville is to this fault.

An earthquake similar to those of 200+ years ago would cause tremendous damage here.
