The map shows quakes of M1.5 and up from the last 90 days, the 3 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, 1 earthquakes of M1.5 or bigger were recorded within 100 km of Chapman, the biggest of them M2.6. Over the past year, M3.0+ quakes near Chapman came at 0.5× the usual pace — quieter than normal for this area. The biggest quake on record near Chapman — records go back to 1980 — was the M4.3 of Dec 08, 2021, 13:45 UTC: 6 km SSW of Gypsum, Kansas.
How we figure this: 2 quakes of M3.0 or bigger within 100 km in the last 12 months (Nov 03, 2025 – Nov 03, 2026), compared with an average of 4.4 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.

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 03, 2026, 19:45 UTC · page built Nov 03, 2026, 19:45 UTC. How to read this page: recent-window counts cover M1.5+ events within 100 km; 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.
