Coal mine subsidence — the sinking, shifting, or cracking of the ground caused by the collapse of abandoned underground mines — is a real and documented risk in northeast Pennsylvania. Standard homeowners insurance policies do not
cover this type of ground movement, leaving many homeowners unaware that a major structural loss could be uninsured. To be protected, families must add a separate endorsement or policy specifically designed for mine subsidence coverage. Carey Insurance Agency in Avoca, PA helps Lackawanna and Luzerne County homeowners understand this unique regional risk and make informed decisions about protecting their property.
If you live anywhere in northeast PA, especially near older mining communities, here’s what you need to know about home insurance and mine subsidence.
What Is Coal Mine Subsidence?
Mine subsidence occurs when an old underground coal mine — often abandoned decades ago — collapses or shifts, causing the ground above it to sink or crack. Northeastern Pennsylvania, particularly Lackawanna and Luzerne counties, sits on miles of historic anthracite mining tunnels. Many of these tunnels were poorly mapped or never reinforced, which means even homeowners several blocks away from known mines can be affected.
Signs of subsidence may include:
- Cracks in walls, ceilings, or foundation blocks
- Sudden sinking or sloping floors
- Tilting chimneys or porches
- Gaps around windows and door frames
- Uneven settling around the home
These warnings can appear gradually or suddenly — and because ground movement can compromise a home's structural integrity, repairs are often expensive and extensive.
Why Mine Subsidence Is a Local Concern in Northeast PA
From Scranton to Wilkes‑Barre, Pittston to Hazleton, the region’s history is deeply tied to anthracite coal mining. Many mines were closed long before modern safety standards existed. Over time, wooden supports deteriorated, water seeped into tunnels, and voids grew unstable.
Even homeowners who believe their property sits nowhere near a mine may be closer than they think. Maps from the early 1900s were incomplete or lost, and mining companies often extended tunnels unpredictably. This uncertainty is precisely why mine subsidence remains a major regional concern.
Carey Insurance Agency works with homeowners across Avoca and surrounding towns who want to understand whether their home could be at risk — and whether subsidence coverage makes sense for their property.
What a Standard Homeowners Policy Covers (and Doesn’t)
One of the biggest misconceptions among Pennsylvania homeowners is that their homeowners insurance covers any type of ground movement. Unfortunately, that is not the case.
Covered Under Standard Homeowners Insurance
Most home insurance policies in Pennsylvania cover sudden and accidental damage such as:
- Fire and smoke damage
- Wind and storm damage
- Burst pipes
- Theft and vandalism
- Damage caused by falling objects (such as healthy trees)
These protections remain the backbone of a home policy — but they do not extend to subsurface activity or long‑term changes in ground stability.
Not Covered Under Standard Homeowners Insurance
Ground movement of any kind is universally excluded. This includes:
- Mine subsidence (from underground mine collapse)
- Sinkholes
- Earthquakes
- Settling or shifting of the foundation
- Ground contraction or expansion
Because mine subsidence falls under the category of excluded ground movement, a homeowner experiencing structural damage from a collapsing mine would not receive any compensation
under a typical home policy.
How to Add Coal Mine Subsidence Coverage in Pennsylvania
Pennsylvania offers mine subsidence insurance through a specific program designed to protect homeowners in mining regions. This coverage can be added as a separate endorsement or stand‑alone policy, depending on the insurer and property location.
Coverage generally applies to:
- Structural damage to the home caused by mine collapse
- Damage to garages, sheds, or other detached structures (with appropriate limits)
- Costs associated with stabilizing the foundation or ground movement
Most homeowners are surprised to learn that mine subsidence coverage is both accessible and relatively affordable. Cost varies based on home value and structure type but often runs far lower than other forms of property insurance.
Why Subsurface Coverage Isn't Automatically Included
Subsurface damage can be severe, progressive, and difficult to predict, which is why insurers exclude it from standard home policies. Without a specific coverage program dedicated to mine subsidence, the financial risk to insurance carriers would be significant — and premiums for all homeowners would increase dramatically.
Instead, Pennsylvania has created a targeted system allowing residents in mining‑impacted counties to add the coverage only when needed, keeping traditional home insurance premiums manageable while still offering protection for at‑risk households.
Why Northeast PA Homeowners Should Discuss This with a Local Agent
Understanding subsidence risk requires local knowledge — something national carriers or automated quote platforms can’t always provide. An independent agent familiar with Lackawanna and Luzerne counties can evaluate the unique characteristics of your neighborhood, the age of your home, nearby mining history, and any known geological concerns.
How Carey Insurance Agency Helps Homeowners
At Carey Insurance Agency in Avoca, PA, we regularly help homeowners explore whether mine subsidence coverage makes sense based on:
- Location in relation to known or suspected mining areas
- Age and construction style of the home
- Signs of settling or structural changes
- Local soil composition and neighborhood history
- Cost and coverage comparisons
Because we’re an independent agency, we review multiple carriers and provide straightforward guidance based on your home’s specific risk factors — not generic assumptions.
What to Do If You Suspect Mine Subsidence Damage
If you notice cracking, sinking, or unusual structural changes, don’t ignore the signs. Early evaluation is key to preventing further damage. Homeowners should:
- Document all visible problems with photos and notes
- Contact a structural engineer for an inspection
- Review their insurance policy to determine if subsidence coverage is active
- Speak with their insurance agent about next steps
Even if you are unsure whether the issue is related to ground movement or normal settling, it’s better to ask questions early.
FAQ

No. Standard home insurance policies exclude all forms of ground movement, including mine collapse.
Is mine subsidence coverage expensive?
It is generally affordable and varies based on home value. Many homeowners are surprised at the low cost.
How do I know if my home is at risk?
A local independent agent can help assess the regional mining history and whether subsidence coverage is recommended.
Can subsidence damage be repaired?
Yes, but repairs can be costly and often require structural reinforcement — another reason coverage is so important.
