Morris's Seismic Design Category, explained

Morris carries Seismic Design Category A under USGS's ASCE 7-16 model. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Morris ranks above 13% of the 4,875 cities in this dataset for seismic hazard - the 13th percentile.

How Morris compares

The raw figures: peak ground acceleration 0.038g, short-period spectral response 0.078g, 1-second spectral response 0.022g. Among 155 Minnesota cities in this dataset, Morris ranks 1 for seismic hazard, the 100th percentile within the state. About 5,192 people live in Morris, Minnesota.

What a retrofit costs in Morris

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Minnesota. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Morris home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Morris address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Morris's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
