How earthquakes affect property prices
Seismic risk is one of the few factors that lowers property values for a long time and in a measurable way. This is not a forecast but a finding from markets where the risk has been officially mapped and prices can be tracked for years.
- New Zealand. After the 2010–2011 earthquakes, land in Christchurch was classified by liquefaction risk. By the third year, homes in the highest-risk category had lost 17.7% of their value relative to neighbouring land, and the gap has held steady at around 13%.
- California. When a plot is placed inside an official active fault zone, its value falls by 6.6% on average and its rent by 3.3%.
- Tokyo. According to the official seismic hazard map, land in the riskiest zones is about 10% cheaper than in the safest ones.
- Japan overall. Before major earthquakes, buyers barely priced in seismic risk. Afterwards, the discount in hazardous areas became noticeable and more than doubled.
What this means for a buyer
Three patterns repeat across all these markets.
- Prices react to visible risk. A discount appears once the risk is officially disclosed or the country has lived through a strong earthquake. Earlier risk maps of Christchurch that nobody paid attention to had no effect on prices.
- The building matters more than the country. Within the same city, the biggest discounts hit buildings constructed before current seismic codes, on weak soils or close to a fault. In Istanbul this has shown up in bank valuations since 2023.
- Commercial property is penalised harder. In Wellington, commercial buildings officially classified as earthquake-prone sell for 45% less on average.
For an investor, an earthquake map is therefore not geography but part of the valuation of a property. It shows how likely a shock that changes the price is, and in which parts of the country it is more likely.
What to check before buying in a seismic country
- The year of construction and which edition of the seismic code the building was designed to.
- The type of soil and the distance to active faults.
- Earthquake insurance: whether it is mandatory and what it covers.
- For high-rises, an independent structural report, not just the developer’s documents.
Earthquakes in Panama and the property market
Between 1926 and 2026 the map window contains 137 earthquakes of magnitude 6 or more, 9 of them of magnitude 7 or more. The strongest was M 7.7.
Panama City lies close to the active Pedro Miguel and Limón faults. Estimates suggest that a joint rupture of the two could produce an earthquake of about M 7.
The REP-2021 building code has been in force since 30 April 2023. The first mandatory code was adopted in 1984, so the year a building was completed tells you directly which requirements it was designed to. There are no studies of how seismic risk affects house prices in Panama; the patterns from other markets serve as a guide.
Questions and answers
- Does seismic risk affect property prices?
- Yes. Studies from Japan, California, New Zealand and Turkey show that housing in high seismic-risk zones is cheaper, and the gap widens after strong earthquakes.
- How much cheaper is housing in earthquake-prone areas?
- Between 2% and 18%, depending on the study. The gap is largest where the risk is officially mapped: 13–18% in Christchurch, about 10% in Tokyo and 6.6% in California.
- What matters more — the country’s seismicity or the specific building?
- The building. Within the same city, the biggest discounts hit buildings constructed before current codes and those on weak soils or near faults.
- Where does the map data come from?
- The USGS ComCat earthquake catalogue: all events of magnitude 4.5 and above from 1926 to 2026, downloaded on 11 October 2026. Faults are drawn schematically from published reviews.
