Storm, Flood, and Earthquake Disaster Insurance is a policy insurance program in the Republic of Korea that compensates for property damage caused by natural disasters, with the national and local governments subsidizing part of the premiums. In the past, it was mainly called “Storm and Flood Damage Insurance,” but its current official name is Storm, Flood, and Earthquake Disaster Insurance, reflecting that earthquake risks are also covered.
As of 01:55 on September 4, 2026, National Safety 24 had posted the current status of typhoon advisories and warnings. Because advisory and warning information changes continuously, actual risk areas and effective times should be checked against the latest National Safety 24 announcement.
Natural Disasters Covered by Storm, Flood, and Earthquake Disaster Insurance
The insurance primarily covers the following natural disasters listed in the policy terms and conditions.
- Typhoons
- Floods
- Heavy rain
- Strong winds
- High waves
- Storm surges
- Heavy snow
- Earthquakes
- Tsunamis
Whether a claim is payable is not determined solely by everyday terms such as the monsoon season or torrential rain. It must be determined whether the actual incident qualifies as heavy rain, a flood, a typhoon, or another covered event under the policy terms and whether the disaster directly damaged the insured property.
For example, a home flooded due to a river overflowing or torrential rain may be eligible for compensation review. In contrast, damage that is not directly related to a natural disaster, such as leaks from aging pipes, defective waterproofing work, or inadequate maintenance, may not be covered by Storm, Flood, and Earthquake Disaster Insurance even if it was discovered at the same time.
Eligible Facilities and Property
Coverage is not available for all property and is limited to facilities specified by laws, regulations, and insurance products.
| Category | Main Insured Property | Matters to Check |
|---|---|---|
| Housing | Residential buildings and movable property inside homes | Owners may primarily insure the building, while tenants may insure movable property they own, such as household belongings |
| Agricultural and forestry greenhouses | Eligible greenhouse facilities, including vinyl greenhouses | Confirm whether facility specifications and intended use meet eligibility criteria |
| Small business commercial premises | Property selected in the contract, such as commercial buildings, facilities and fixtures, and inventory | Confirm small business eligibility and the items actually insured |
| Small business factories | Property selected in the contract, such as factory buildings, machinery and facilities, and inventory | Confirm the insured amount for each business location and item of property |
Because homeowners and tenants own different property, eligible insured property may differ even at the same address. The building is the owner’s property, while a tenant’s appliances, furniture, and similar items are the tenant’s movable property, making it important to verify which property is listed on the insurance policy.
Vehicles, crops themselves, land, and outdoor facilities not included in the contract generally require separate insurance or support programs. Business interruption losses for commercial premises or factories and temporary accommodation expenses are also not automatically covered in full, so riders and policy terms must be reviewed separately.
National and Local Government Premium Subsidy Rates and Policyholder Contributions
Premium subsidy rates vary depending on the eligibility category and whether the policyholder belongs to a vulnerable group. The figures below are representative standards presented in policy guidance, and the actual contribution rate may vary depending on the budget for the relevant year, additional local government subsidies, and the insurance product selected.
| Enrollment Category | Representative Subsidy Rate | Basic Policyholder Contribution Rate After Subsidy |
|---|---|---|
| General housing | Check with the local government and insurer | Calculated according to the subsidy rate |
| Housing for near-poverty households | Check with the local government and insurer | Calculated according to the subsidy rate |
| Housing for basic livelihood security recipients | Check with the local government and insurer | Calculated according to the subsidy rate |
| Housing in disaster-vulnerable areas | Check with the local government and insurer | Calculated according to the subsidy rate |
| Agricultural and forestry greenhouses | Check with the local government and insurer | Calculated according to the subsidy rate |
| Small business commercial premises and factories | Check with the local government and insurer | Calculated according to the subsidy rate |
Some local governments provide additional subsidies for the policyholder’s share under their ordinances and budgets. In some regions or for certain eligible groups, combined central and local government support may cover up to 100% of the premium, but this does not automatically apply to every policyholder nationwide.
For example, if the total premium is KRW 100,000 and the subsidy rate is 55%, the policy subsidy is KRW 55,000 and the basic out-of-pocket contribution is KRW 45,000. If the local government additionally subsidizes part of this contribution, the amount actually paid will be lower. However, because the total premium itself is calculated based on the building structure, area, location, insured amount, and product terms, the example amount cannot be regarded as an actual quote.
Eligibility as a member of a near-poverty household or a basic livelihood security recipient, or recognition as being in a disaster-vulnerable area, cannot be established solely based on the applicant’s own judgment. Administrative information must be checked, and eligibility must be verified by the local government or insurer.
Why Premium Subsidy Rates Vary by Region
Premium support does not consist of a single fixed discount rate but combines national funding, local funding, and the policyholder’s contribution. Accordingly, even for the same type of housing, the final amount paid may vary depending on the following factors.
- Policyholder category, such as a general household, near-poverty household, or basic livelihood security recipient
- Whether the home is administratively eligible for support as property in a disaster-vulnerable area
- Whether the local government provides additional support from its own budget
- Whether funding remains in the additional subsidy budget
- The selected insurance product, insured amount, and deductible
To verify the exact subsidy rate, it is safest to contact both the disaster management department of the city, county, or district where the home or business is located and a participating insurer. The current contribution amount should not be determined solely from another local government’s guidance or a notice from the previous year.
How Insurance Benefits Are Calculated
The premium subsidy rate and the rate of compensation for damage are separate concepts. The fact that the government subsidizes a certain percentage of the premium does not mean that the same percentage of the damage amount will be paid.
Insurance benefits are generally calculated based on the following factors.
- The insured property listed on the insurance policy
- The selected insured amount and coverage limit
- The actual amount of damage or the fixed benefit standards specified by the product
- Deductibles and proportional compensation terms
- A direct causal relationship between the cause of the incident and the damage
- Pre-existing damage or exclusions under the policy terms
- The existence of other insurance covering the same property
Because Storm, Flood, and Earthquake Disaster Insurance includes both fixed-benefit and indemnity or proportional compensation products, it is difficult to simplify the coverage as “payment of all restoration costs.” Fixed-benefit products apply agreed damage criteria and insured amounts, while indemnity products reflect factors such as the actual amount of damage, insurable value, coverage ratio, and deductible. The final criteria are set by the insurance policy and terms of the product purchased.
