Reading source websites
Source websites, climate news, help and legal links open in Apple’s in-app Safari viewer. Done returns to the screen you were reading. Use the viewer’s Open in Safari control to continue in your browser. Official flood documents keep their native document viewer. TCW storm bulletins, plain-text files, CSV source files and BYU iceberg tracking files open in a native text reader, including files served as downloads. Where supplied, TCW warning text appears first, with the full original file available. Source wording and units stay unchanged; unavailable files show Retry. Subscription management, App Store reviews, email and phone actions keep their normal system destinations. Website content still belongs to its publisher and needs a connection.
Purchases and alert connections
If the Pro offer cannot load, choose Retry loading Pro offer. Apple’s offer and your existing subscription are separate checks. Use Subscription details to check access, or Restore purchases with the purchasing Apple Account. Missing information does not prove expiry.
Hazard alerts checks saved server settings. An interrupted screen check can finish after you leave the screen; a genuine connection failure stays visible with Retry connection. Checking status does not delete server rules. Mobile signal bars do not confirm that Apple or the alert service can be reached.
Tsunami reports
Tsunami is a Free event type in World. Browse the latest available NOAA NTWC and PTWC bulletins from the past seven days, open official details, save a copy or share the source. Warning, advisory, watch and information wording stays with the issuing centre. Cards and details show preliminary earthquake magnitude where supplied. This describes the earthquake, not tsunami strength or wave height. Expired and cancellation bulletins are labelled separately. Map pins identify earthquake origins, not affected coastlines or wave positions. These feeds are not a complete warning archive or worldwide coverage, and do not provide tsunami push notifications.
Map controls
Centre restores an individual report or saved-place map. The two-arrow circle is Zoom fully out on every map toolbar, including notification, report and saved-place maps. It goes straight to the widest supported view while keeping your selected report, area, filters and layers. The target is Latest in World and Centre on focused report or saved-place maps. Latest uses the same area, event filters, period and search as Map and List. Neither action changes your selected area. Open the area selector beside the search icon to find a city, region or country, or choose Worldwide to return to the globe. One compact icon toolbar below the map holds navigation, zoom, Style and Full screen. Magnifying-glass zoom icons work around the middle of your current map and grey out at the closest and widest views. Open Key above the map for each tool’s meaning, then Map info, colours & sources for coverage details. Latest is unavailable when no mapped reports match; Map home in the delayed No reports panel keeps your other filters. Report maps and notifications open with wider geographic context. Latest zooms closer to its matching report. Saved-place maps keep their radius framing. Map appearance and options offers Standard, Satellite and Hybrid, plus contextual controls for the available report data. Your appearance choice is remembered across maps. Tap the compass after rotating to face north again. World groups nearby reports into numbered markers, which separate as you zoom. Tap a group to choose a report, or a single marker to open its details directly. Full-screen World keeps area, period and filter controls available. These map controls are free.
Getting started
Open Today for the event feed and a shortcut to your place briefing, World for the map, Warnings for supported official notices, Forecasts for weather and regional outlooks, and Places for locations you follow. Choose Climate inside Today for the longer story. Type a city or town name in Add a place, then tap a suggestion. One place and its briefing are free. Share report sends the report facts and original source link. Share app sends the companion website link, also available in Settings. App sharing does not open an exact event inside the app. For older records, open Settings > Event history. Results open immediately with Earthquakes selected. Choose another supported event type in the same filter, then adjust its period and relevant measurement or source controls. History filters are separate from World and alert preferences. Avalanche forecasts live in Forecasts, with All forecasts and My places choices. Open any event and tap Save event to keep a copy; find it under Saved events in World or Settings. Tap a saved row to open its report. Use Edit or swipe to remove a copy, or choose Remove saved copy inside the report. Removal asks for confirmation.
Browse an area
In World, tap Worldwide to choose a saved place and its radius. Or move and zoom the map: the area updates automatically when you finish. Switch to List to read the same matching reports. Search in List; the same search applies on the map, where Clear search removes it. Selecting the World tab starts again at the latest available earthquake with a wide map view and clears the previous World search. If no reports match, the map stays clear and your filters remain applied. Move the map again to choose a different area. Area changes filter reports already loaded; they do not request every feed again. Open Map info for coverage, source checks, map colours and country warnings. Choose Worldwide to see matching loaded reports across the world. Clear filters, inside Filters, keeps your current area and search. World saves filter preferences, while selecting the World tab resets the event type, earthquake minimum and period for its latest-earthquake overview. Today keeps its own daily overview. Map & list on Today opens the latest available earthquake in a wide map view, using worldwide earthquakes from the past 24 hours without a magnitude minimum. After a place search, panning or zooming switches to Map area and updates matching reports as you move and when the map settles. Your event type, thresholds and period remain applied. Changing event types or thresholds keeps the area you chose. Event and period choices check the relevant sources automatically, reusing fresh reports and downloads already in progress. World shows update problems for the selected reports, with a retry beside the message. Event pages and report history check their sources when opened or changed too. Use Latest in the map toolbar to centre and highlight the newest matching mapped report in your selected area. After the map has been still for one second, an empty area shows a small No reports panel in the top-left corner. Map home returns to worldwide coverage with the other filters retained. The panel fades in over half a second. Moving the map or tapping Map home fades it away over half a second. Opening the World tab starts at the latest available earthquake. Panning and automatic feed updates do not keep pulling you back. A named preset opens its saved area. This is free browsing. It uses reported points, not country borders or affected-area boundaries, and does not enable notifications. Pro can save multiple named map presets, including their areas. A saved-place preset uses that place’s current radius and returns to Worldwide if the place is removed or unavailable.
Read more inside a report
Earthquakes can include expandable USGS shaking maps, felt-report maps and town/population estimates. Tap a map to enlarge it. These are source estimates, not confirmed losses or shaking at your saved address. NOAA storms include pressure, movement and a native official advisory. NASA event descriptions, dated observation history and additional supplied source links appear where available. USGS explanations and NOAA forecast discussions can be read inside the report. Tsunami is a Free World event type with map/list browsing, source-labelled bulletin details, saving and sharing. The latest NOAA NTWC/PTWC feeds supply bulletins issued within seven days, not a complete archive. World map/list results, counts, Latest and Fit include current bulletins only. Recent bulletins opens expired source reports separately, and cancellation bulletins have their own labelled route. Current bulletins remain eligible for Today highlights and available in Warnings. Expiry does not itself mean an all-clear. Cards and report details show preliminary earthquake magnitude where supplied, labelled separately from the official tsunami bulletin type. It is not a tsunami strength or wave-height reading. Pins mark the earthquake origin, never threatened coastlines, and do not match a saved-place radius. Coverage follows those issuing centres; no tsunami push notifications are provided. These browsing details are Free and add no push notifications.
Pro earthquake history loads in batches of 500. Use Load more reports for older matches within the selected period, never beyond one year. Small-earthquake coverage varies. The original source link stays available in every report.
Managing alerts
In Places, open a saved place and choose Hazard alerts. Free includes a fixed 200 km preset for one place: earthquakes M2+, any reported storm wind, selected wildfire reports, USGS volcano notices and supplementary NASA volcano reports, selected GDACS floods at all impact colours, and all England flood alert and warning levels. Open Settings, then Hazard alerts, and choose your saved place. Add a place there if needed. For optional global G1+ notifications, open Geomagnetic storms in the same list. No saved place is needed. Worldwide monitoring for other supported hazards is labelled Pro. Choose your settings and tap Done to apply them and close. If a rule is off in the app but still saved on the server, enable that same rule and tap Done to reconnect it. Its settings are saved only after the server accepts them. If applying fails, the screen stays open with an error and the changes are not applied. Tap a mapped hazard notification to open World centred on that exact report, with its circle highlighted. Tap the circle for full details. Browse World opens a fresh earthquake overview at the widest zoom, centred on the latest available earthquake. It shows the past 24 hours with no magnitude minimum and clears earlier report-wording searches. Today Explore and the World tab use the same entry. A notification opens World immediately; if its exact report needs downloading, Opening your report appears with a progress indicator. Failed loads offer Try again or Browse World. Reports without a map position, including geomagnetic activity, open their details directly. A delivered test does not confirm that later edits were saved. Send a test notification applies pending changes before testing, so there is no separate Save button. Cancel lets you discard edits. The status distinguishes a saved rule from confirmed delivery: check that the test appears on your iPhone. Connection failures offer a retry. If iPhone permission was denied, use Open iPhone Settings. Both plans include quiet hours and a test notification. Choose different start and end hours. The timezone follows the iPhone when the app next reconnects. Confirmation messages stay with the relevant control. Test results appear beside Send a test notification, and validation messages appear with the setting that needs attention. Turning off a saved rule does not require a new push token. Pro lets you select earthquake, storm, wildfire, volcano, flood, UK weather warnings and the eight additional report types, with source-appropriate controls, distance and quiet hours. Low, Medium and High set all adjustable minimum levels in the current rule. Low allows more alerts; High is more selective. Adjust any event below afterwards; Custom shows when the levels differ from the presets. The buttons keep event switches, distance, chosen warning types and quiet hours. The place or Worldwide switch controls only that rule. When it is off, its options are greyed out and your choices are kept. Shared quiet hours stay available for your other rules. Reports without adjustable levels stay on/off. Coverage is source-specific, not complete worldwide warning coverage. No separate app account is needed. You can manage permission in iPhone Settings too. Open How alerts work in the app for coverage and notification details.
How alerts work
Alerts can be delayed or missed. Always follow official advice.
Newly discovered earthquake reports can qualify up to two hours after the earthquake. Once accepted, delivery is attempted for up to 30 minutes from first discovery, subject to your rules and service availability. Later source edits do not restart that window. Initial setup and recovery after a long outage do not send a backlog.
Notifications put the main reported fact first: earthquake magnitude followed by depth in miles and kilometres, observed G level for geomagnetic storms, reported wind for storms, reported area where supplied for wildfires, and the official level for England floods and USGS volcano notices. Location, source and report time follow. Storm wind leads in mph, retaining knots and km/h; wildfire area leads in acres, retaining hectares. Missing measurements are not treated as zero.
Usually one notification per matching event. Each new USGS volcano activity notice or status report can notify separately. Floods can notify again when the official warning level changes. Coverage varies by source; tsunami notifications are not available. Nearby alerts need a reported location. Reports without a location can still match worldwide alerts. Quiet hours mute notifications for all your alerts, and muted notifications are not sent later. Incident alerts report source events. Met Office Weather Warnings describe forecast impacts within their supplied validity periods and affected areas.
Managing your subscription
Pro is an annual subscription. Open Settings or the Pro screen and choose Manage subscription to view or cancel it in your Apple Account. Cancellation stops the next renewal; access continues until the paid period ends. After expiry, you can keep using Free features, including one saved place. Your extra saved places are retained on the device for when Pro is active again. Server rules fall back to basic alerts at the first enabled place when Pro verification or access ends. An enabled geomagnetic rule continues at G1+; other worldwide and custom rules stop. The app retains that first enabled place for Free access, or the first saved place if none has alerts. Turning off Free place alerts preserves enabled geomagnetic alerts, and vice versa. Earlier Pro rules are reduced to the Free preset. Turn off all notifications in Settings > Hazard alerts stops alerts for every saved place and worldwide events. The action changes to Turn notifications back on after a successful switch-off. Review the previously enabled places and global alerts, then tap Done to restore them. If no previous selection was recorded, choose which alerts to enable. Changed subscription access requires a new choice using the current Free or Pro options. Earlier versions call this Remove server alerts.
Restoring Pro
Open the app’s Settings, choose World of Warning Pro, then Restore purchases. Use the Apple Account with the active subscription. An expired subscription does not restore Pro access. On the Pro screen, open Subscription details to see the available verified purchase period, recorded expiry and last check. Where Apple supplies them, it also shows renewal status, automatic renewal, billing grace end and the expiry reason. Subscription details checks again when opened. Expiry, renewal status and automatic renewal remain visible, with Not available from Apple when missing. Check subscription retries the check. A missing or unverifiable purchase is distinguished from a period that has ended. Test purchases are labelled separately. Device purchase status does not confirm server alert delivery.
Country weather notices
In World, open Key, then Map info, colours & sources, then Weather warnings by country. The Warnings tab shows notices across supported countries immediately. Opening Warnings automatically checks stale or failed sources and continues checking while open. Recent successful country checks are reused for up to four minutes. Pull down for an immediate check, or use Retry beside a failed check. Country, type and weather severity are optional filters. Avalanche, landslide, wildfire, drought, dust/haze and fog notices have explicit type filters where supplied. Regional US avalanche forecasts retain their own danger ratings; weather severity does not filter them. My places matches forecasts to a saved US state, not an address or radius. The US list also filters by state or territory and searches supplied wording. Heat, wind, thunderstorm, snow and other published notices are free to browse where supplied. The selected feed checks every two minutes while the screen is active. Empty results use the selected notice type without a zero-count heading. Coverage explanations are in the info sheet; source failures remain visible. This has the same country coverage limits as the flood browser and does not enable additional push notifications.
Flood warnings outside England
In World, open Key, then Map info, colours & sources, then Flood warnings by country, or open the Warnings tab. All warnings shows supported feeds immediately; My places shows country or US state notices for your saved places. Country and minimum severity are optional filters. Moderate or higher includes Severe and Extreme. All severities includes unknown levels. US notices also have a state or territory filter and search of supplied area and warning wording. Warnings is available to Free and Pro. Country notices are broad-area information, not a determination that an address is affected. US and MeteoAlarm notices are free to browse. They do not enable push notifications. England map filters retain England’s own levels. For worldwide reports choose All flood reports, then All impact colours, Orange and red or Red only. The higher-impact choices show GDACS reports only, using its separate impact scale. Search the World list by country to find loaded reports. An empty list does not prove that no flooding or local warnings exist.
Today artwork
The app’s illustrative Today banner plays a silent eight-second animation once per app opening, then settles into a still image. Returning from another tab or scrolling does not replay it. Reduce Motion keeps it still. The clip is bundled in the app and needs no download. Website artwork remains still.
Missing or delayed data
Open Sources & coverage on Today, or through Key and Map info in World, to see each feed’s last successful check and any failures. Reports check automatically while the app is in use. Opening Today, World, Warnings or Places checks missing, stale or failed report sources. This also applies to individual country notices and place briefings, with shared checks when you move between screens. Pull down to check again; Retry appears beside failures. Climate observations use a slower check interval, and saved event copies remain fixed. Manual checks show Checking, then a readable result and check time. Earthquake details distinguish Report updated from No changes found; failures remain visible. The check time is separate from the source report date. ReliefWeb’s server download time is also shown separately, so a healthy snapshot within its 15-minute cache period does not cause a false update warning. If our cache service fails, public browsing feeds can retry their original provider. ReliefWeb stays on the shared server cache to protect its quota; older downloaded records remain labelled, without being presented as fresh highlights. This does not restore push notifications or services needing private keys. A successful check does not mean every report was newly published. Preliminary earthquake reports can change. A location with no reports may have incomplete monitoring coverage.
