The map shows quakes of M1.5 and up from the last 90 days, the 8 biggest on record, and always the very latest quake — even if it was smaller than M1.5. The list below can include smaller ones the map leaves out. Tap any dot for details.
In the last 30 days, 9 earthquakes of M1.5 or bigger were recorded within 100 km of Biggs, the biggest of them M2.8. Over the past year, M3.0+ quakes near Biggs came at 2.8× the usual pace — busier than normal for this area. The biggest quake on record near Biggs — records go back to 1980 — was the M5.1 of Aug 10, 2016, 02:57 UTC: 20 km NNE of Upper Lake, California.
How we figure this: 5 quakes of M3.0 or bigger within 100 km in the last 12 months (Nov 04, 2025 – Nov 04, 2026), compared with an average of 1.8 a year across the full calendar years 2016–2025, counted the same way. This compares how often quakes happened in two past periods. It is not a forecast, and it does not mean a big earthquake is on its way — nobody can predict earthquakes.
Does a busier spell mean a bigger earthquake is coming?
Short answer: nobody can tell — and a busier spell by itself is not a warning sign. Bunches of small quakes are common around Biggs, and most settle down on their own. Small quakes also do not “let off steam” that would prevent a big one: a single M7 releases roughly as much energy as 32,000 M4 quakes added together. Earthquakes cannot be predicted. What can be measured is the long-term pattern — the biggest quakes on record near Biggs are listed further down this page.

Earthquakes per year near Biggs (M3.0 and up, within 100 km)
M3.0–3.9 M4.0+
Each bar is one year; taller means more quakes (M3.0 and up). The dark red part is the bigger ones (M4.0+), counted inside the number above each bar — not added on top. These may be felt, depending on how far away and how deep they are. 2026 is not a full year yet — it only counts up to today. Source: USGS Earthquake Catalog.

USGS data fetched Nov 04, 2026, 02:45 UTC · page built Nov 04, 2026, 02:45 UTC. How to read this page: recent-window counts cover M1.5+ events within 100 km, measured from the center of the place, not the city limits; the 10-year layer is based on M3.0+ and the history layer on M4.0+ since 1980. Recording completeness varies by era and region — small quakes from early decades are under-recorded, so “no record” does not prove “never happened”. Depths are relative to sea level and can be slightly negative for shallow events in elevated terrain. Method: data & methodology.
