Does Pennsylvania Actually Have Earthquakes?

More than most residents think. Pennsylvania has recorded earthquakes going back to 1737, and the eastern part of the state sits near enough to the Lancaster seismic zone and the Ramapo fault system in New Jersey that noticeable events reach Montgomery County periodically. The 5.8 magnitude Virginia earthquake in 2011 was felt clearly across the Philadelphia suburbs, rattling buildings from Lansdale to Willow Grove, and the 4.8 magnitude New Jersey earthquake in April 2024 shook homes across the entire region and was followed by dozens of aftershocks.

Nobody is suggesting Montgomery County is California. Our risk is low frequency. But it is not zero, and eastern quakes have a peculiar property: because the bedrock here is older, colder, and more continuous than the fractured rock out west, seismic energy travels much farther. An earthquake that would be a local event in California is felt across several states here. Combine that with the region's housing stock — older masonry homes, stone foundations, and unreinforced brick chimneys that were never built with lateral movement in mind — and moderate shaking can produce real damage to structures that would shrug it off elsewhere.

Why Doesn't My Homeowners Insurance Cover Earthquake Damage?

Because earth movement is a named exclusion in every standard HO-3 form. The exclusion is broad: it covers earthquakes, tremors, aftershocks, landslides, mudflow, sinkholes, and subsidence. If a quake cracks your foundation, drops your chimney through the roof, or shakes your basement walls out of plumb, your homeowners insurance will not respond to any of it.

There is one narrow exception worth knowing. If an earthquake ruptures a gas line and the resulting fire burns your house, the fire damage is covered as a fire claim — fire following earthquake is generally not excluded. But the shaking damage itself is not. Insurers exclude earth movement for the same reason they exclude flood: it is a catastrophic peril that hits thousands of homes at once in a concentrated area, which is unworkable inside a standard policy. That is why it is sold separately, exactly like flood insurance — another coverage most Montgomery County homeowners assume they have and don't.

What Does Earthquake Insurance Cover — and How Does the Deductible Work?

Earthquake coverage in Pennsylvania is usually added as an endorsement to your existing homeowners policy, though standalone policies exist. A typical policy covers:

• The dwelling: Structural repairs to the foundation, walls, roof, and chimney.

• Personal property: Belongings damaged by shaking — furniture, electronics, china, and anything that comes off a shelf or wall.

• Additional living expenses: Hotel, meals, and rent if your home is uninhabitable while repairs are made.

• Other structures: Detached garages, sheds, and in some forms, retaining walls and hardscaping.

What is typically excluded: land itself, swimming pools and hardscaping in many forms, vehicles (those fall under the comprehensive portion of your auto insurance), and any damage from flooding, including a tsunami or dam failure triggered by a quake.

The deductible is the part that surprises people. Earthquake deductibles are percentage-based rather than flat, commonly 2% to 20% of your dwelling coverage limit. On a Lansdale home insured for $500,000, a 5% deductible means you pay the first $25,000 before the policy contributes anything. That structure is why earthquake coverage is best understood as catastrophic protection against a home you cannot live in — not as coverage for hairline plaster cracks. Choosing the right percentage is the single most important decision on the policy, and it is worth talking through rather than defaulting.

How Much Does Earthquake Insurance Cost in Montgomery County, PA?

Here is the good news about living in a low-risk seismic zone: the coverage is cheap. Adding an earthquake endorsement to a Pennsylvania homeowners policy commonly runs somewhere in the range of $25 to $150 per year for a typical home — meaningfully less than the same coverage would cost in California or Washington. Premium depends on your dwelling limit, the deductible percentage you choose, and construction: a wood-frame home generally rates better than unreinforced masonry, because frame flexes and brick doesn't.

Age matters too. Much of the housing in Lansdale, Horsham, and Willow Grove predates modern seismic construction standards entirely, and older stone or brick foundations are exactly the structures most vulnerable to lateral movement. Not every carrier writing home insurance in Pennsylvania offers the endorsement, and the ones that do price and structure it differently. As an independent agency, we can check across our carriers rather than telling you it isn't available because one company doesn't offer it.
