sisma: Earthquake Map & Alerts

Felt a tremor? Open sisma to see what just happened, where, and how strong.

sisma is a live earthquake tracker for the whole world. It brings together reports from four seismic agencies, USGS, EMSC, GeoNet and JMA, so each earthquake appears once, with its magnitude, depth, time and distance from you. Follow seismic activity from Japan, Indonesia and the Philippines to Turkey, Italy, Greece, California, Mexico, Chile and New Zealand.

WHAT JUST SHOOK?
• A live feed of earthquakes, sorted by latest, nearest or strongest
• Magnitude, depth, time and distance for every event, with its country and whether it has been reviewed
• Region view zooms in on any quake and shows the others nearby, so you can follow aftershocks
• On tablets, an overview with daily activity, quakes by magnitude and the most active regions

LIVE EARTHQUAKE MAP AND 3D GLOBE
• A world map centred on you, with tectonic plate boundaries
• Zoom from the whole planet down to street level
• Spin a 3D globe, then switch to depth view to see how deep each quake struck
• Filter by time range and place

DID YOU FEEL IT?
• Report the shaking you felt in the first hours after an earthquake
• See where others felt it on a felt map, shown only as anonymous counts by area

SHARE WHAT HAPPENED
• Share any earthquake as a picture with a map of the area, plus ready-written post text and image description that you can edit

UNDERSTAND EARTHQUAKES
• Eight illustrated guides: plate tectonics, fault types, seismic waves, magnitude and intensity (and how they relate to the Richter scale), depth, tsunamis, how to prepare, and the Pacific Ring of Fire with a live map
