MagmaSync

Kīlauea Volcano Monitor

What is MagmaSync?

MagmaSync is an app for iPhone, iPad, Mac, and Apple Watch that helps you stay informed about Kīlauea volcano activity on Hawaii's Big Island. It displays real-time data sourced from the U.S. Geological Survey (USGS) Volcano Hazards Program and Hawaii Volcano Observatory (HVO), and delivers eruption forecasts and push notifications.

MagmaSync is designed for general awareness and educational purposes. It is not an emergency alert system and is not affiliated with or endorsed by the USGS or any government agency. Always rely on official sources for safety-critical information.

Frequently Asked Questions

Why am I not getting notifications?

First, check your iPhone system settings: Settings → Notifications → MagmaSync and ensure notifications are allowed.

Inside the app, tap the settings icon in the top-right corner and verify that the individual notification toggles are enabled: Status Update, Message Update, and Next Forecast Window.

Note that notifications may experience network or processing delays. They are delivered via Firebase Cloud Messaging and are not guaranteed to arrive in real time. Notifications are for informational purposes only.

How accurate is the eruption forecast?

The eruption forecast window is updated periodically based on available volcano monitoring data from USGS and past eruption history. However, volcanic activity is inherently unpredictable and conditions can change rapidly without warning.

The forecast is provided for general awareness only. Do not use it to make safety decisions.

What do the alert levels mean?

There are two parallel alert systems displayed in the app:

Volcano Alert Level describes ground-based volcanic hazards: Normal, Advisory, Watch, or Warning.

Aviation Color Code describes hazards to aircraft from volcanic ash: Green, Yellow, Orange, or Red.

In most cases they move together, but they can differ when ground hazards and aviation hazards are at different levels. Both systems are defined by the U.S. Geological Survey (USGS); full definitions are published on the USGS Volcano Hazards Program site.

Can I use MagmaSync in an emergency?

No. MagmaSync is NOT an emergency service.

In a volcanic emergency, always follow instructions from your local civil defense authority (e.g., Hawaii Emergency Management Agency), consult official USGS and HVO communications directly, and call 911 if there is an immediate threat to life.

App data may be delayed or inaccurate. Do not rely on MagmaSync for evacuation decisions or other safety-critical actions.

What data source does the app use?

MagmaSync displays data sourced from the U.S. Geological Survey (USGS) Volcano Hazards Program, specifically the Hawaii Volcano Observatory (HVO). USGS data is produced by the U.S. Government and is in the public domain.

MagmaSync is not affiliated with or endorsed by the U.S. Geological Survey or any U.S. government agency.

How do I change my notification settings?

In the app, tap the settings icon in the top-right corner of the main screen. Under Push Notifications, you can toggle on or off:

  • Status Updates — alert level or aviation color code changes
  • Message Updates — new messages from HVO
  • Next Forecast Window Updates — updated eruption forecast windows

If toggles are grayed out, check your iPhone system notification permissions at Settings → Notifications → MagmaSync.

What languages are supported for translation?

MagmaSync uses Apple's on-device Translation framework, which supports 50+ languages. Supported languages depend on your device's iOS version and installed language packs. A language pack may need to download on first use; after that, translation works offline.

For AI Summaries (Apple Intelligence), supported languages are determined by your device's Apple Intelligence language configuration.

Translations are machine-generated and may be inaccurate, especially for technical or scientific volcanic monitoring terminology. Do not rely on translated content for safety decisions.
