Chesterton, IN: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Chesterton in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Chesterton ranks above 32% of the 4,875 cities in this dataset for seismic hazard - the 32th percentile.

Where Chesterton sits in Indiana

USGS's underlying values for Chesterton: 0.053g peak ground acceleration, 0.109g at short period, 0.064g at 1 second. Within Indiana alone, Chesterton ranks 121 of 126 cities by seismic hazard - the 4th percentile in-state. Chesterton has a population of about 14,655.

Bracing and bolting: the actual cost

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.

Earthquake insurance for a Chesterton home

A Chesterton 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 Chesterton's figures come from

Chesterton's Category B 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 B does and doesn't tell you about Chesterton.
