NewQuake: Earthquake Tracker

Tsunami waves that follow the real ocean. The wave front is now worked out from the depth of the sea it crosses, so it bends around islands, speeds up and slows down with the seafloor, and ends where it reaches land. Where a warning center publishes arrival times, the front is matched to them. Tsunami forecast points show the expected wave height. Each coastal point is colored by how high the wave is expected to be, with a legend to read it by, lights up at its own arrival time, and opens a card with the details when you tap it. Live, for the big ones. A great earthquake's waves cross the ground for about ten minutes, and a tsunami bulletin stands for hours. While one of those is still running it is marked LIVE in Recent, on the Map, on its page and in the widget, and the map draws the waves where they are right now. Small quakes are usually over before the first report arrives, so this is for the events that last.
