Significant Earthquakes - 2026
USGS Earthquake Hazards Program, responsible for monitoring, reporting, and researching earthquakes and earthquake hazards
earthquake.usgs.govI don’t have live access right now, but I can share how to check today’s earthquakes and what to watch for.
-
Quick sources to monitor
- USGS Earthquake Hazards Program: real-time global earthquakes, with magnitudes, locations, and aftershock info.
- EarthquakeTrack: daily totals, biggest quakes today and in the past 24 hours.
- EMSC: real-time seismic data for Europe and global events; good for cross-checks.
-
What to look for today
- Magnitude and depth: higher magnitudes (above 6) are rarer but can cause more damage; shallow quakes (low depth) often feel stronger near the epicenter.
- Epicenter regions: note if activity clusters in a region (plate boundaries like the Pacific Ring of Fire, Eurasian Plate boundaries, etc.).
- Tsunami alerts: coastal regions near large offshore quakes may trigger tsunami warnings.

Quick alert tips for São Paulo, Brazil
- Brazil is not at a major plate boundary, so significant offshore or intraplate earthquakes are less common locally, but nearby regions (Caribbean, South Atlantic margins) can influence felt reports. If you feel shaking, assess safety first (drop, cover, hold on) and check official alerts for any region-specific guidance.
Would you like a concise, current-day briefing with the top 3 earthquakes of today and any active tsunami or regional alerts? If you specify, I can provide a structured summary and safe-action steps.
