Protect your home from seismic phenomena

What would happen if your house was severely damaged or completely destroyed in an earthquake tomorrow? Even worse, what would happen to your finances if, in this catastrophic scenario, your insurance company refused to reimburse you because you didn’t check the right box on your policy?

It is not a very pleasant thought, but if you own property, it is a risk you must take into account.

We know that Southern Europe, and specifically Portugal, sits on active fault lines. It is impossible to predict exactly how or when, but seismologists continuously warn that the earth will eventually shake again, just as it did during the devastating Lisbon earthquake of 1755. The material damage resulting from an event of that magnitude is incalculable.

However, while it is impossible to predict an earthquake, it is entirely possible to financially protect yourself from its consequences. In this Folime financial guide, we will explain exactly how «Seismic Coverage» works, what it covers, and why every homeowner should strongly consider adding it to their policy.

The Reality of Home Insurance in High-Risk Zones

«Prevention is the best medicine» is a popular saying that applies perfectly to real estate. The absolute best way to protect your life savings is to take out a Multi-Risk Home Insurance policy that explicitly includes coverage against seismic phenomena.

The statistics are alarming: There are approximately 3.8 million single-family homes with an active multi-risk home insurance contract in Portugal, but only 19% of them are actually covered against seismic phenomena. The vast majority of homeowners mistakenly assume that standard «fire and flood» insurance automatically covers earthquakes. It does not!

What Exactly is Seismic Coverage?

Seismic Coverage (Cobertura de Fenómenos Sísmicos) is an optional add-on (a rider) to your standard Multi-Risk Home Insurance.

It guarantees financial compensation for damage caused to your insured property following the direct action of:

• Earthquakes and tremors.
• Volcanic eruptions.
• Tsunamis (tidal waves caused by the quake).
• Underground fires and surface fires resulting directly from these phenomena.

Crucial Insurance Rule: Most policies stipulate that all tremors, aftershocks, and related damage that occur within a continuous 72-hour period from the first tremor will be considered as one single claim.

How Does This Coverage Protect Me?

In the devastating event of an earthquake, multi-risk home insurance with seismic coverage protects your physical home and the assets inside it. Depending on your contract, it generally guarantees payment for:

• Demolition and Debris Removal: The heavy cost of hiring excavators to safely clear the rubble of the destroyed property.
• Contents Protection (Recheio): Compensation for the destroyed furniture, electronics, and personal belongings inside the home.
• Total Reconstruction: The massive cost of rebuilding the physical property from the ground up, paying the architects, builders, and material costs.

Alternatively, if your home is completely destroyed and the land is deemed unsafe, you can often choose to simply receive the cash payout (up to the limit of your contracted capital) to purchase another property elsewhere.

The Math: How Much Does Seismic Coverage Cost?

Multi-risk insurance provides a series of basic covers, and the premium is calculated based on what you add to it. In the case of seismic phenomena, the specific price is calculated by the insurer based on three main geographic and structural factors:

1. The Age of the Property: Older homes without modern, anti-seismic steel reinforcements are much more likely to collapse, making them more expensive to insure.
2. The Seismic Risk Zone: A house built in the Algarve or Lisbon (historically high-risk seismic zones) will cost significantly more to insure against earthquakes than a house built in the deep interior of the North.
3. The Construction Type: A concrete and steel-reinforced villa is cheaper to insure than an old masonry or stone house.

Understanding Capital Limits and Deductibles

Beyond the age and location of your house, your final bill depends heavily on the financial choices you make when signing the contract:

• The Insured Capital: This must correspond exactly to the rebuilding cost of your home, not its market value. If you under-insure your home (e.g., insuring a €200k rebuild cost for only €100k to get a cheaper premium), the insurer will apply the pro-rata rule. This means if half your house falls down, they will only pay half the claim, leaving you financially ruined.
• The Deductible (Franquia): Seismic coverage usually carries a high mandatory deductible, typically set at 5% or 10% of the total insured capital. This means if your insured capital is €100,000 and you have a 10% deductible, you are personally responsible for paying the first €10,000 of the repairs out of pocket. Choosing a higher deductible (10%) will significantly lower your monthly premium, but increases your personal financial risk.

💡 A Financial Tip from the Folime Team:
Avoid nasty surprises when the ground shakes. Pull out your current Home Insurance policy today and check the «Excluded Risks» section. If you live near the coast or in a known fault zone, call your insurance broker and ask for a simulation to add Seismic Coverage. The peace of mind of knowing your family will not be left homeless and in debt is worth the small increase in your monthly premium.
