Real-Time Earthquake Monitor Guide
Track live earthquakes worldwide with real-time magnitude, depth, and epicenter data from the USGS seismic feed.
Overview
Monitor seismic activity across the globe in real time using the US Geological Survey (USGS) Earthquake Hazards feed. Filter by magnitude and time window to track tectonic movements directly in your browser.
When to Use Real-Time Earthquake Monitor
Use Real-Time Earthquake Monitor to stay informed on global seismic events, verify news of recent tremors, or conduct academic geology research.
Inputs, Formats & Specifications
- Accepted Inputs
- Magnitude filter (M1.0+, M2.5+, M4.5+, Significant), timeframe selector (hour, day, week)
- Output Formats
- Real-time earthquake feed cards, magnitude badges, focal depth, epicenter coordinates, USGS event links
- Supported Standards
- USGS GeoJSON, ISO 8601 UTC timestamps
- Browser Limits & Scope
- Data reflects USGS seismograph reporting; minor local tremors under M1.0 in regions without dense sensor coverage may not appear.
How to use Real-Time Earthquake Monitor
- Select your minimum magnitude filter threshold (e.g. M1.0+, M2.5+, M4.5+) and observation timeframe.
- Click 'Fetch Live Feeds' to query the latest USGS GeoJSON seismic telemetry directly from your browser.
- Browse the interactive earthquake cards sorted by most recent occurrence or highest magnitude.
- Click on any earthquake event card to inspect focal depth, coordinates, and direct links to USGS scientific event pages.

Frequently Asked Questions
Where does the earthquake data come from?
Data is sourced in real time from the US Geological Survey (USGS) Earthquake Hazards Program public GeoJSON feeds.
How frequently is the seismic feed updated?
USGS updates its real-time feeds every 1 to 5 minutes. LilUtils caches responses for 2 minutes to ensure polite consumption.
What does earthquake focal depth indicate?
Focal depth is the depth beneath the Earth's surface where the rupture began. Shallow earthquakes (0–70 km) generally cause more intense ground shaking at the surface than deep earthquakes.
