🌍 '''Earth movement coverage''' is a property insurance provision that protects policyholders against physical damage caused by natural shifts in the earth's surface, including [[Definition:Earthquake insurance | earthquakes]], [[Definition:Landslip coverage | landslides]], sinkholes, mudflows, and volcanic eruption. In many standard [[Definition:Commercial property insurance | commercial property]] and [[Definition:Homeowners insurance | homeowners]] policies, earth movement is specifically excluded from the base form, requiring insurers to offer it as a separate endorsement, standalone policy, or government-backed program. The scope and availability of this coverage vary dramatically by geography — in earthquake-prone regions such as Japan, New Zealand, California, and Turkey, dedicated earth movement products are a critical component of the insurance landscape, often supported by national pools or [[Definition:Catastrophe reinsurance | catastrophe reinsurance]] arrangements.

⚙️ How earth movement coverage functions depends heavily on the regulatory and market environment. In the United States, the [[Definition:California Earthquake Authority (CEA) | California Earthquake Authority]] provides residential earthquake coverage through a publicly managed but privately funded mechanism, while in Japan, earthquake insurance for residential properties is underwritten through a co-insurance arrangement between private insurers and the government's Japan Earthquake Reinsurance Company. Policies typically carry higher [[Definition:Deductible | deductibles]] than standard property coverage — often expressed as a percentage of the insured value rather than a flat dollar amount — reflecting the [[Definition:Catastrophe risk | catastrophic]] and correlated nature of earth movement events. Insurers rely on sophisticated [[Definition:Catastrophe model | catastrophe models]] from vendors such as [[Definition:Risk Management Solutions (RMS) | RMS]], [[Definition:AIR Worldwide | AIR Worldwide]], and CoreLogic to price this peril, factoring in soil type, fault proximity, building construction, and historical seismicity. [[Definition:Reinsurance | Reinsurance]] and [[Definition:Insurance-linked securities (ILS) | insurance-linked securities]] play an outsized role in supporting capacity for earth movement risk, given the potential for single-event losses that dwarf normal portfolio volatility.

💡 The financial significance of earth movement coverage extends well beyond individual claim payments. Major seismic events — such as the 2011 Tōhoku earthquake and tsunami, the 2010–2011 Canterbury earthquake sequence in New Zealand, and the 2023 Turkey–Syria earthquakes — have reshaped entire insurance markets, triggering reforms in building codes, [[Definition:Underwriting | underwriting]] standards, and government insurance schemes. For insurers and [[Definition:Reinsurer | reinsurers]], managing earth movement exposure is a defining element of [[Definition:Enterprise risk management (ERM) | enterprise risk management]], directly influencing [[Definition:Regulatory capital | capital requirements]] and [[Definition:Solvency | solvency]] assessments under frameworks like [[Definition:Solvency II | Solvency II]] and the [[Definition:Risk-based capital (RBC) | RBC]] system. The persistent challenge of the protection gap — the difference between economic losses from earth movement events and insured losses — remains one of the industry's most pressing public policy concerns, driving innovation in parametric products, microinsurance, and public-private partnerships worldwide.
