A notification for the whole family
When an earthquake of magnitude 4.5 or more hits within about 60 miles of someone in your circle — or a 6.0 or stronger within about 185 miles — everyone in the circle who can see that person gets a notification: “M6.1 earthquake · Dominican Republic — 8 mi from Emma. Tap to see if everyone is OK.” If the U.S. Geological Survey flags a possible tsunami, the notification says so first.
Each person gets one notification per earthquake, about the family member closest to it.
The seismograph card
Smaller earthquakes nearby (magnitude 4.0 or more within about 90 miles) show on the Circles screen in a dark card with a seismograph line: the magnitude, how long ago it was and who in the family was closest.
The map, with everyone on it
Tap the card and the map opens full screen: the epicenter, rings at 12 and 31 miles, and each person in the family who was near it. Slide up the sheet to see the depth, where it happened and how far it was from each of you. One tap shares an “I’m OK” message with the family in Messages, WhatsApp or any app you use.
After the shaking, never before
FamTrip3 checks for new earthquakes every minute, so the family hears about it within minutes. It doesn’t predict earthquakes and it doesn’t warn you before the shaking starts — official early-warning systems do that, and your phone may already get those alerts from your government. FamTrip3 is for the moment after: is everyone OK?
The same privacy rules as the map
A notification only mentions people you can already see on the map. Someone in private mode doesn’t trigger it, and kids only hear about the people they’re allowed to see. Read about adults and kids and privacy controls.
Official data
The earthquakes come from the U.S. Geological Survey (USGS), which publishes earthquakes from around the world in near real time. Distances show in miles, or in kilometers if you use them.
