A new report by Home Gnome identifies cities at highest risk for earthquake damage in 2025, evaluating factors like seismic activity, building age, and proximity to fault lines. While California and Oregon dominate the list, unexpected entries like Memphis and Oklahoma City also rank high due to lesser-known seismic hazards.


1. San Francisco, CA (Risk score: 57.59)

San Francisco tops the list, home to 800,000 residents near the San Andreas Fault. Historic quakes, like the 1989 7.1-magnitude Loma Prieta earthquake, killed 63 people and caused $6 billion in damage. The city’s dense population and aging infrastructure amplify risks.

2. Los Angeles, CA (53.03)

LA’s proximity to the San Andreas Fault and high population density make it vulnerable. The 1994 6.7-magnitude Northridge quake caused 60 deaths and $20 billion in losses. Modern building codes mitigate risks, but experts warn of inevitable future shocks.

3. Coos Bay, OR (50.61)

Coos Bay faces threats from the Cascadia Subduction Zone, capable of magnitude 9+ megaquakes. A 1700 quake triggered a tsunami reaching Japan. Scientists warn the fault is overdue for another rupture, risking catastrophic damage.

4. Memphis, TN (50.55)

Shelby County sits on the New Madrid Seismic Zone, responsible for the 1811–1812 quakes that reversed the Mississippi River. A magnitude 5.0 quake in 1865 damaged Memphis, and experts warn of a 40% chance of a magnitude 8.4 event within 50 years.


5. Oakland, CA (49.90)

The Hayward Fault, dubbed a “tectonic time bomb,” runs beneath Oakland. A 6.8-magnitude quake in 1868 devastated the Bay Area. Today, a repeat could displace 500,000 residents and ignite widespread fires.

6. Portland, OR (49.70)

Portland’s danger stems from the Cascadia Subduction Zone and local faults like the Portland Hills. A 5.6-magnitude quake in 1993 caused $28 million in damage. A Cascadia rupture could leave the city isolated by landslides for weeks.

7. Ukiah, CA (49.60)

Despite its small population (16,000), Ukiah lies near the Maacama Fault. The 1906 7.9-magnitude San Andreas quake damaged the city, highlighting risks for rural communities near major faults.

8. Oklahoma City, OK (49.42)

Oklahoma’s surge in fracking-linked quakes peaked with a 5.7-magnitude event in 2011, damaging highways and homes. Though induced seismicity has declined, the Nemaha Fault poses ongoing risks.


9. San Bernardino, CA (49.15)

Adjacent to the San Andreas Fault, San Bernardino faces frequent tremors. The 1992 7.5-magnitude Landers-Big Bear quakes destroyed 77 homes countywide, underscoring vulnerabilities in inland California.

10. San Mateo, CA (49.14)

This coastal city near the San Andreas Fault risks tsunamis post-quake. The 1989 Loma Prieta quake caused panic but minimal damage; future events could destabilize its shoreline communities.


Takeaway: Earthquake preparedness is critical, especially in high-risk zones. Modern building codes and public awareness can mitigate disasters, but unexpected regions like Tennessee and Oklahoma prove that seismic threats exist far beyond the West Coast.
