Newport, OR: what USGS's seismic model says

USGS's ASCE 7-16 seismic model can't even fit Newport onto its standard code table - ground motion here (peak ground acceleration 0.797g) is past what the table covers, which under §11.4.8 means a site-specific geotechnical study, not a standard letter grade. Nationally, Newport ranks above 98% of the 4,875 cities in this dataset for seismic hazard - the 98th percentile.

Where Newport sits in Oregon

USGS's underlying values for Newport: 0.797g peak ground acceleration, 1.633g at short period, 0.766g at 1 second. Within Oregon alone, Newport ranks 4 of 80 cities by seismic hazard - the 96th percentile in-state. Newport has a population of about 10,833.

What a retrofit costs in Newport

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 Oregon 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 Oregon.

What this means for insurance

A Newport 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 Newport's figures come from

Newport's Category rating 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 does and doesn't tell you about Newport.
