Science

The Science tab has eight short illustrated guides, each with an animated diagram or a live chart: plate tectonics, fault types, seismic waves, magnitude and intensity, depth and aftershocks, tsunamis, how to prepare, and the Ring of Fire, with a live map of how many recent earthquakes struck around the Pacific.

Tap the buttons under a diagram to switch views, and the pause button to stop the animation. The guides follow your language, like the rest of the app. Tap Share at the top of a guide to send it to someone, with its picture, a short summary and the link.
