Mooresville, IN: what USGS's seismic model says

Mooresville carries Seismic Design Category C under USGS's ASCE 7-16 model. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. Rank it against the rest of the country and Mooresville sits at the 71th percentile for seismic hazard among 4,875 US cities.

How Mooresville compares

USGS's underlying values for Mooresville: 0.107g peak ground acceleration, 0.207g at short period, 0.091g at 1 second. Within Indiana alone, Mooresville ranks 23 of 126 cities by seismic hazard - the 82th percentile in-state. Mooresville has a population of about 10,027.

Retrofit economics for Mooresville

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Indiana specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Indiana.

Insuring against this, not just retrofitting

A Mooresville homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Mooresville's figures come from

Mooresville's Category C and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category C does and doesn't tell you about Mooresville.
