📊 '''Earthquake risk''' denotes the probability and potential severity of financial loss to [[Definition:Insurance carrier | insurers]], [[Definition:Reinsurance | reinsurers]], and [[Definition:Policyholder | policyholders]] arising from seismic events. It is one of the defining [[Definition:Catastrophe risk | catastrophe risk]] categories in the [[Definition:Property insurance | property insurance]] market because earthquakes combine low frequency with extremely high severity, meaning a single event can produce billions of dollars in [[Definition:Insured loss | insured losses]] while decades may pass between major occurrences in any given region. This volatility makes earthquake risk particularly challenging to [[Definition:Underwriting | underwrite]], price, and reserve for.

🔬 Quantifying earthquake risk relies heavily on [[Definition:Catastrophe model | catastrophe models]] that integrate seismological science, engineering vulnerability functions, and exposure data. Models simulate thousands of potential seismic scenarios — varying magnitude, depth, location, and ground conditions — to generate [[Definition:Loss exceedance curve | loss exceedance curves]] and [[Definition:Probable maximum loss (PML) | probable maximum loss]] estimates. Carriers use these outputs to set [[Definition:Premium | premiums]], determine [[Definition:Deductible | deductible]] structures, establish [[Definition:Aggregate limit | aggregate limits]], and design [[Definition:Reinsurance program | reinsurance programs]]. Because model uncertainty remains significant — fault rupture behavior is inherently difficult to predict — prudent risk managers stress-test results and may layer additional conservatism into their assumptions. [[Definition:Rating agency | Rating agencies]] and regulators examine how well an insurer's [[Definition:Capital | capital]] position can withstand modeled earthquake loss scenarios when assessing [[Definition:Solvency | solvency]] and granting operating authority.

🌐 From a market perspective, earthquake risk drives some of the most innovative [[Definition:Risk transfer | risk transfer]] structures in the industry. The [[Definition:Insurance-linked securities (ILS) | ILS]] market, including [[Definition:Catastrophe bond | catastrophe bonds]] and [[Definition:Collateralized reinsurance | collateralized reinsurance]], was partly born out of the need to spread peak earthquake exposure beyond the balance sheets of traditional reinsurers — particularly after landmark events like the 1994 Northridge and 2011 Tōhoku earthquakes. Public-private partnerships such as the [[Definition:California Earthquake Authority (CEA) | California Earthquake Authority]] and Turkey's TCIP further illustrate how the magnitude of earthquake risk compels collaboration between governments and the private [[Definition:Insurance market | insurance market]]. Closing the [[Definition:Protection gap | protection gap]] for earthquake remains a priority across the industry, with [[Definition:Insurtech | insurtech]] firms exploring parametric triggers and microinsurance solutions to extend coverage to underserved populations.
