World of Warning: Earthquakes

See where natural events are being reported, understand the facts and follow places that matter to you.

World of Warning brings earthquakes, storms, wildfires, floods and other environmental reports into one iPhone app. Start with Today, explore the World map or open a report for measurements, context and the original source.

EXPLORE FOR FREE • Browse reported events on a map or in a searchable list. • Choose event types and relevant filters, including earthquake magnitude. • Open official weather and flood notices from supported countries, including UK Met Office warnings. • Read five-day England and Wales flood risk, official flood outlook documents and supported US avalanche forecasts. • See earthquake depth, shaking and impact information where supplied. • Browse recent official USGS volcano activity and status notices. • Add nine optional geology map layers, including plate boundaries and the Ring of Fire. • Save one place, read its briefing and keep copies of reports. • Look back through up to seven days of earthquake reports and selected recent event records. • Explore temperature, carbon dioxide and El Niño observations, with two years of available climate data. • Choose optional basic alerts at one place and global G1+ geomagnetic alerts. • Open the original facts behind an earthquake notification and view later USGS revisions separately.

MORE WITH PRO An optional annual subscription adds Apple Weather current conditions, hourly forecasts and a ten-day outlook, up to ten saved places, custom alert thresholds and distances, UK Met Office warning alerts, worldwide rules for supported hazards, named map presets, earthquake history up to twelve months, and longer climate records with 30-year and full-record views.

ALERTS YOU CONTROL See which alerts are on, turn all notifications off in one place, and restore your previous choices when you are ready. With Pro, choose Low, Medium or High minimum levels, then fine-tune each supported event type.

CLEAR SOURCES AND CONTEXT Reports identify their source and date. Depending on the event, sources include USGS, NOAA, NASA EONET, GDACS, the Environment Agency, the Met Office, the Flood Forecasting Centre and participating national warning services. Official warning levels, reported measurements and model estimates keep their separate meanings.

No ads. No separate app account required.

Coverage varies by provider and region. Reports can be delayed, revised or unavailable. Flood reports include England official warnings and selected GDACS reports. US NWS and MeteoAlarm country notices are for browsing; Pro supports UK Met Office warning alerts. Apple Weather forecasts describe the saved point and do not add forecast push alerts. Tsunami bulletins are limited to the supplied NOAA-centre coverage and do not trigger pushes. The app is not an earthquake prediction or early-warning service and does not replace local authorities or emergency services.

SUBSCRIPTION Pro is an annual auto-renewable subscription. Apple shows the local price before purchase. Payment is charged to your Apple Account. It renews unless cancelled at least 24 hours before the current period ends. Manage or cancel in Apple Account subscription settings. Free features remain available without subscribing.
