Yorktown, IN: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Yorktown in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Yorktown ranks above 46% of the 4,875 cities in this dataset for seismic hazard - the 46th percentile.

Yorktown by the numbers

USGS's underlying values for Yorktown: 0.071g peak ground acceleration, 0.143g at short period, 0.075g at 1 second. Within Indiana alone, Yorktown ranks 68 of 126 cities by seismic hazard - the 46th percentile in-state. Yorktown has a population of about 11,900.

What a retrofit costs in Yorktown

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 Yorktown home

A Yorktown 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.
