Cumberland, IN: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Cumberland is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Cumberland in the 54th percentile nationally for seismic hazard - higher than 54% of the 4,875 US cities USGS was checked against here.

How Cumberland compares

USGS's underlying values for Cumberland: 0.091g peak ground acceleration, 0.178g at short period, 0.083g at 1 second. Within Indiana alone, Cumberland ranks 45 of 126 cities by seismic hazard - the 65th percentile in-state. Cumberland has a population of about 7,211.

Retrofit economics for Cumberland

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 Cumberland 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 Cumberland's figures come from

Cumberland'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 Cumberland.
