Cleveland, MS: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Cleveland is Category D. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. That puts Cleveland in the 80th percentile nationally for seismic hazard - higher than 80% of the 4,875 US cities USGS was checked against here.

How Cleveland compares

USGS's underlying values for Cleveland: 0.152g peak ground acceleration, 0.298g at short period, 0.138g at 1 second. Within Mississippi alone, Cleveland ranks 14 of 61 cities by seismic hazard - the 78th percentile in-state. Cleveland has a population of about 10,183.

What a retrofit costs in Cleveland

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 Mississippi 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 Mississippi.

Earthquake insurance for a Cleveland home

A Cleveland 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 Cleveland's figures come from

Cleveland's Category D 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 D does and doesn't tell you about Cleveland.
