In 2025, fire departments serving Corona responded to 113 fire and hazmat incidents — from cooking fires to gas leaks to a single $150K building blaze. Here's the full picture.
Incomplete 2025 data. Corona's departments reported 113 incidents to NFIRS for 2025, against about 434 in a typical year, so 2025 figures on this page undercount. The 2021–2025 totals are the better guide.
Forest, woods or wildland fire lead by count. Building fires lead by dollars. Together the top five categories make up about 52% of all calls.
Jan peaks. Apr dips. Watch for the typical fall climb starting in October.
2,171 incidents 2021–2025. Peak year was 2023. $13.2M cumulative property loss. 3 civilian deaths.
| Year | Incidents | YoY | |
|---|---|---|---|
| 2021 | 449 | — | |
| 2022 | 514 | +14.5% | |
| 2023 | 553 | +7.6% | |
| 2024 | 542 | -2.0% | |
| 2025* | 113 | — |
* Well below Corona's usual volume. That almost always means one or more departments didn't submit a full year to NFIRS, not that fires dropped, so no year-over-year change is shown for it.
For the 3 building fires Corona departments responded to in 2025, here's how they were classified once investigators were finished.
NFIRS Area of Origin (AREA_ORIG) for the 1,065 building fires investigators classified across 2021–2025. The room or location where ignition occurred — kitchens, bedrooms, exterior, vehicle areas — tells you where to focus prevention.

Top 10 ZIP codes by NFIRS incident count across 2021–2025. Each ZIP has its own fire profile — dive in for neighborhood-level context.
Six California cities with population within ±25% of Corona. Useful comparison targets — same state, similar size, different fire profile.
A 30-minute weekend can cut your home's exposure substantially. These four checklists are a good starting point.
Numbers reflect incidents reported by participating fire departments to the National Fire Incident Reporting System (NFIRS) Public Data Release for calendar year 2025. NFIRS is voluntary — about 23,000 of roughly 30,000 US fire departments report — so totals are a strong indicator, not a complete census. Per-capita comparisons use 2023 ACS population estimates. Wildland fire data complements NFIRS with NIFC and USFS perimeters. Active-fire counts come from a dated NIFC snapshot, not a live feed.
