Earthquake

Defined A sudden movement of the earth’s crust caused by the release of stress accumulated along geologic faults or by volcanic activity. A sudden release of energy in the earth’s crust or upper mantle, usually caused by movement along a fault plane or by volcanic activity...

Defined A series of vibrations induced in the earth’s crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating. A sudden movement of the Earth’s lithosphere (it’s crust and upper mantle)... -thefreedictionary.com

Measuring Intensity Magnitude Earthquake Effects Estimated Number Each Year 2.5 or less Usually not felt, but can be recorded by seismograph. 900,000 2.5 to 5.4 Often felt, but only causes minor damage. 30,000 5.5 to 6.0 Slight damage to buildings and other structures. 500 6.1 to 6.9 May cause a lot of damage in very populated areas. 100 7.0 to 7.9 Major earthquake. Serious damage. 20 8.0 or greater Great earthquake. Can totally destroy communities near the epicenter. One every 5 to 10 years

Why Do We Care? Property policies don’t cover earth movement!!! Commercial Property Exclusions Homeowner’s Exclusions

ISO 2012 Commercial Property Policy

Commercial Property Exclusions Earthquake and related events

Commercial Property Exclusions Earthquake and related events Landslide

Commercial Property Exclusions Earthquake and related events Landslide Mine subsidence

Commercial Property Exclusions Sinking, rising or shifting

Commercial Property Exclusions Sinking, rising or shifting Ensuing fire or explosion IS covered

2011 ISO Homeowners Policy

Homeowner’s Exclusions Earthquake and related events

Homeowner’s Exclusions Earthquake and related events Landslide, mudslide, and mudflow

Homeowner’s Exclusions Earthquake and related events Landslide, mudslide, and mudflow Subsidence or sinkhole

Homeowner’s Exclusions Anything else we forgot

Homeowner’s Exclusions Anything else we forgot Concurrent causation exclusion

Homeowner’s Exclusions Anything else we forgot Concurrent causation exclusion Ensuing loss by fire, explosion, or theft IS covered

Underwriting Concerns Brick or concrete built before 1940 Loss assessment coverage unless the master policy covers it Magnitude 5.0 Veneer coverage Location, location, location

Deductibles Commonly MUCH higher than the property deductible for other losses. Percentage of value, not loss Commercial deductibles can apply per building or per item

Commercial Property Endorsement

Commercial Property Endorsement Earthquake

Commercial Property Endorsement Earthquake Volcanic eruption

Commercial Property Endorsement Earthquake Volcanic eruption 168 hour period (7 days)

Commercial Property Endorsement Sprinkler leakage from earthquake

Commercial Property Endorsement Sprinkler leakage from earthquake Sprinkler leakage from volcanic eruption

Commercial Property Endorsement Sprinkler leakage from earthquake Sprinkler leakage from volcanic eruption Policy expiration does not reduce the 168 hour period

Provisions Earth movement exclusion does not apply to earthquake

Provisions Earth movement exclusion does not apply to earthquake Collapse is covered for earthquake and volcanic eruption

Deductible Issues Deductible applies per item, not per loss

Deductible Issues Deductible applies per item, not per loss Policy valuation provisions apply

Deductible Issues Specific insurance for reporting form Blanket insurance Builder’s risk

Homeowner’s Endorsement

Homeowner’s Endorsement Earthquake

Homeowner’s Endorsement Earthquake Volcanic eruption

Homeowner’s Endorsement Earthquake Volcanic eruption 72 hour period (3 days)

Homeowner’s Endorsement Earthquake Volcanic eruption 72 hour period (3 days) Does not increase limits

Typical Limitations

Typical Limitations No other structures coverage

Typical Limitations No Coverage B Percentage Deductible

Typical Limitations No Coverage B Percentage Deductible ACV loss settlement

Typical Limitations No Coverage B Percentage Deductible ACV loss settlement Exterior masonry veneer inclusion or exclusion

Exclusions

Exclusions Flood

Exclusions Flood Filling land

Concurrent Causation Flood Filling land Tidal wave and Tsunami

Points To Remember The Earth Movement exclusion is not deleted. WE ONLY GIVE BACK EARTHQUAKE!!! Loss Assessment Other concurrent loss issues...

Points To Remember Sinkhole collapse is STILL not covered by the homeowner’s form Theft IS a covered ensuing loss on the homeowner’s form Coinsurance issues Alternate form issues
