How close does an earthquake need to be to count as near Santa Rosa?

The default local search uses a 100 km (62 mile) radius from the city-center coordinates. You can switch the explorer to 50 km or 300 km, and the selected circle is drawn on the map.

What does the historical section for Santa Rosa include?

It summarizes M4.0+ earthquakes within 300 km during the previous ten complete calendar years. The broader radius and higher magnitude threshold are shown separately so the historical totals are not confused with the live local feed.

How current is the earthquake data?

QuakeScout checks the USGS catalog every five minutes. Preliminary magnitude, depth, and location values can be revised after scientific review.

Can QuakeScout be used as an emergency alert?

No. QuakeScout is an informational catalog interface, not an earthquake prediction or emergency warning service. Follow official local authorities and emergency alerts.

How This Santa Rosa Tracker Works

The live explorer starts with M2.0+ events within 100 km during the past 30 days. Changing a filter requests a new result set from the USGS Event Web Service; it does not estimate or invent seismic activity.

An epicenter may be outside the city boundary. Magnitude measures energy released at the source, while felt shaking also depends on distance, depth, local geology and construction. “No matching events” means none met the displayed catalog filters.
