Risk Factors
Preparedness Recommendations
Anchor tall furniture, water heaters, and heavy appliances to wall studs. Use museum putty for items on shelves.
Keep 72 hours of water (1 gallon/person/day), food, flashlight, batteries, first-aid supplies, and important documents in a grab bag.
Standard homeowner's insurance does not cover earthquake damage. Earthquake insurance costs vary by location; Bucks County has relatively low expected losses.
Learn how to turn off gas, water, and electricity. After a significant quake, gas leaks are a leading cause of post-earthquake fires.
Be Prepared for Earthquakes
FEMA recommends every household have a 72-hour emergency supply kit ready.
Earthquake Emergency Kit — $60-120 →Earthquake Risk in Carversville, PA
ZIP code 18913 has relatively low earthquake risk with a FEMA seismic score of 3.8/100. Major seismic events are less likely here, but no area is completely immune to earthquake damage.
Understanding Seismic Risk
The FEMA National Risk Index calculates earthquake risk based on three components:
- Hazard exposure — probability and intensity of seismic ground motion based on USGS data
- Vulnerability — building types, age, and construction materials that determine damage potential
- Social vulnerability — community factors that affect recovery capacity
Bucks County Earthquake Profile
Bucks County has an expected annual loss rating of relatively low compared to other U.S. counties. The total estimated annual economic loss from earthquake damage is $1,502,135, which includes building damage, content loss, and business interruption.
The annual frequency of damaging earthquakes in this area is very low (3.60e-4), but the USGS notes that low-probability events can still cause severe damage when they do occur.
Structural Preparedness
Even in lower-risk areas, basic earthquake preparedness protects your family and property:
- Secure water heater ($15-50 DIY or $200 professional) — prevents tipping and gas line rupture
- Anchor furniture ($5-20 per item) — prevents toppling of bookcases, dressers, and TV stands
- Flexible gas connections ($20-80) — allows some movement without breaking gas lines
About This Assessment
This assessment uses FEMA National Risk Index seismic data for Bucks County, PA. The risk score reflects area-level hazard, not individual building vulnerability. Actual damage depends on soil type, building construction, foundation type, and distance from fault lines.

Frequently Asked Questions
What does my earthquake risk score mean?
Your earthquake risk score (0–100) is based on USGS seismic hazard data and FEMA expected annual loss estimates for your county. Higher scores indicate greater likelihood and potential severity of earthquake damage. The score combines seismic frequency, historical events, structural vulnerability of local housing, and estimated financial losses.
How can I prepare my home for an earthquake?
Secure your water heater with straps, bolt your home to its foundation (cripple wall bracing), and anchor heavy furniture to walls. Keep a 72-hour emergency kit with water, food, flashlight, and first-aid supplies. Know how to shut off gas and water. If your home was built before 1980, consider a seismic retrofit evaluation — many cities offer rebate programs.
Is earthquake insurance worth it?
It depends on your risk zone and financial situation. Earthquake insurance typically carries a high deductible (10–25% of dwelling coverage), meaning you pay a significant portion of damage costs yourself. In high-risk areas like California, the CEA offers policies starting around $800/year. In low-risk areas, the cost may not justify the coverage. Review your risk score and expected loss estimate to decide.
