REVEALED: US cities most at risk of major earthquake damage this year

Home Gnome evaluated 206 of the largest US counties based on earthquake risk, the median age of homes, the number of dams in the area and other metrics to assess their impact risk.

They calculated a risk score for each county (out of 100 points) and ranked them from least vulnerable to most vulnerable.

Some places on the list are unexpected, including Tennessee and Oklahoma .

Multiple areas in California and Oregon , two of the most earthquake-prone states, made the list as well.

Memphis is located on the southern edge of the New Madrid Seismic Zone , one of the most seismically active regions east of the Rock Mountains .

The New Madrid has a 40 percent chance of releasing an 8.4 magnitude earthquake in the next 50 years .

Alameda County , home to the city of Oakland , came in fifth place with a risk score of 49.9 points.

Oakland is affected by smaller faults that branch off of the San Andreas fault, including the Hayward , which runs directly through this city and has produced earthquakes as strong as magnitude 7.8 in 1868 .

San Bernardino was rocked by a cluster of three earthquakes on February 10 .

The largest — a magnitude 3.6 — struck around 10pm local time, and no damages or injuries were immediately reported.
