Tsunami bulletins from the Pacific Tsunami Warning Center now show the earthquake's origin time and depth, and their threat level comes from the forecast in the bulletin. Links to a tsunami bulletin open the right one, and distant earthquakes reported by Japan's JMA now show where they happened. Live notifications have their own section in Settings, with a note on what they do. A quake whose waves are nearly over is no longer announced. Smoother P and S wave replay in the Depth card, LIVE badges that clear as soon as an event is over, and a Map options menu that opens and closes cleanly. Uses less memory. Past the first 24 hours, Recent now keeps M4.5+ earthquakes for the week instead of M4+, along with notable and rare events. New installs start in the Dark theme. You can change it in Settings > Appearance.

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.

NewQuake now runs on iPad. Press and hold anywhere on the Map to view underground. A vertical slice through the crust opens at that point, with the mapped faults, the sinking plate at its modelled thickness, and the earthquakes that sit on the cut. Expand it full screen, or turn it to the perpendicular cut through the same place. The Depth picture on an event page now replays the P and S waves leaving the hypocenter, and turns the same way. Share an earthquake from its event page. Anyone who has NewQuake opens the same event. The weekly map tour flies last week's Notable quakes rather than a fixed magnitude floor, and the feed loads faster and holds less memory.

Volcanoes now stay on the Map for as long as they are erupting, with the Smithsonian Global Volcanism Program weekly activity report filling in eruptions other agencies close early. Subduction faults on the Map always show which plate is diving beneath the other, and how fast it moves. A new Depth card on every event page puts the quake depth in context, against the seafloor above it and, where one is mapped, the subducting slab it sits on. Tsunami forecasts now read straight from the official bulletin, so the assessment matches what the agency actually issued. A faster, smoother Map: quicker launch, better-paced rupture replays, and a refined Last week M5.5+ quake tour.

Earthquakes now arrive as sequences. Aftershocks group under their mainshock, drawn as connectors on the map and linked from every event page, so a whole sequence reads at a glance instead of as a scattered list. The Map tab is rebuilt. It flies to each new quake as it arrives, replays the fault rupture in place, and colors every quake by how old it is: red in the past hour, then orange, yellow, and white as it ages, down to grey. Active faults are colored by slip rate and plate boundary, and a single options menu now holds every layer and legend. Explore the past on the same map, with guided tours of the great historical earthquakes and rare seismic events. Richer event pages: focal mechanism beachballs, more accurate P and S wave propagation, a fault plane chosen from the evidence, and a note when agencies disagree. The app keeps a week of events and a year of landmark quakes and backfills daily, so Recent and the Map are already full when you open them. Search the Recent feed by place or term, tap an alert to land on that quake on the map, and watch rows update as agencies revise them.

Watch each quake unfold. Replay the P and S seismic waves spreading from the epicenter across the globe and the detail map, with ShakeMap shading where shaking was strongest. New Historical Quakes browser on the Map tab: the great and giant earthquakes of the past, plotted and replayable. A new satellite look for the Map tab and event backdrops, with active faults near each event and richer detail for major quakes - released energy, fault type, felt reports, JMA shindo for Japan, and a rupture map. Track multiple locations alongside GPS, each with its own alert range and magnitude threshold, and a new Settings summary showing exactly what you are covered for. Smarter alerts: a real-time connection delivers qualifying events sooner, alerts follow escalations, tsunami all-clears tell you when the danger passes, and an Alert Delivery status in Settings confirms notifications are working. Search the Recent feed, where notable quakes stay pinned to the top with the real event type - earthquake, quarry blast, or explosion - right in the feed. A new Glossary in Settings and on every event page explains the technical terms in plain language, and the Home Screen widget now follows the app appearance setting.
