Global seismic activity
Overview of features, filters, and controls
Explore seismic events in full 3D orthographic projection. Drag to pan and rotate the globe, scroll or pinch to zoom. Use the Layers menu (top right of map) to choose basemaps (Light, Dark, Street, Satellite, Terrain) and toggle tectonic plates or the aerial survey.
Marker size reflects Earthquake Magnitude. Colors represent Focal Depth from shallow to deep (Green <10km → Yellow/Orange 10–70km → Red/Purple >70km). Click any marker to view time, depth, magnitude, and tsunami notices.
Switch between 1h, 24h, 7d, 30d feeds or choose custom historical periods. Search by city, region, or country (e.g. Japan, Chile, California), or tap Min Mag chips to filter out lower magnitudes.
Click Feed List in the toolbar to slide out the activity list. Click any earthquake entry to automatically fly directly to its coordinates and pop open its detailed event card.
Click Timelapse to replay earthquake occurrences step-by-step chronologically across your chosen time range. Scrub the progress bar or pause at any moment to analyze clusters.
Assess real-world earthquake impact with official USGS PAGER alert badges (Green, Yellow, Orange, Red) and Mercalli Intensity (MMI) indicators. Export your current filtered earthquake view to CSV or GeoJSON anytime via the Feed List header.
Filter between natural tectonic events and human-induced seismicity (quarry blasts, mining explosions, rock bursts). Human-induced tremors trigger custom explosive acoustic sonification and amber alert badges.
Track the Victorian retro-fantasy dirigible fleet — nine ships in three squadrons — orbiting the planet between the major parallels. Each flagship leads two smaller escort ships patrolling between the Arctic Circle, the tropics, and the Antarctic Circle. When new earthquakes are detected in their region, the whole squadron blows its unique steam whistle and pings its bowsprit searchlights with the earthquake's depth color (Green <10km → Blue/Yellow/Orange 10–70km → Red/Crimson >70km):
Click any ship or the HMS Aetheria button to inspect live 3D models, flight telemetry, and test each squadron's authentic whistle and depth beacon.
