TREMOR

Tremor

A live, interactive view of recent earthquakes across the planet, built on the USGS real-time feeds.

• Drag to spin the globe · scroll / pinch to zoom.
• Search any country or city to fly straight there.
• Watchlist — save locations (home, family, suppliers, sites) with a radius + magnitude threshold and get alerted the moment a quake strikes nearby, with optional browser notifications.
• Sign in for cloud monitoring — your watchlist syncs to the server, which watches it 24/7 and sends alerts to Slack/Discord webhooks or email even when this page is closed.
• Click a quake to fly to it and load its data + ShakeMap intensity contours right on the globe.
• Time machine swaps the live feed for the biggest quakes since 1900, or every quake in a region (California, Japan, Türkiye…) — press play to sweep a century.
• Scenario sandbox — drop a hypothetical epicenter anywhere, set magnitude + depth, and see the modeled shaking footprint and which cities would feel it.
• Shaking near me — use your location (or search a place) to see the estimated intensity you'd have felt from recent real quakes.
• Portfolio impact (B2B) — bulk-upload your sites (CSV), then triage which are most exposed after any earthquake, with a downloadable impact report.
• Aftershock forecast — for significant quakes, the details panel shows USGS aftershock probabilities by magnitude and timeframe.
• Tsunami travel-time — for large/tsunami-flagged quakes, visualize the wavefront radiating across the ocean in hourly rings.
• Time window + magnitude filter what you see.
• City lights / terminator renders Earth's real day-night line for the selected time.
• Plate boundaries · Fault lines · Volcanoes overlay the geology — the tectonic plates, major named faults (San Andreas, North Anatolian…), and notable volcanoes.

Data refreshes automatically every 60s. Not for emergency use — see USGS for official information.
