Most earthquake apps wait for the official measurement. Sismy tells you the moment people report shaking, then updates as the real solution arrives.
Sismy tells you the moment people somewhere start reporting shaking. The official magnitude follows minutes later, and the alert updates itself as it arrives.
It follows earthquakes everywhere on Earth and tells you about almost none of them. You decide which ones are worth your attention.
SET THE ALERTS UP AROUND YOURSELF
You can pick your country, draw your own area on the map, or set a distance around you. You also decide how big an earthquake has to be before it reaches you.
You can set a separate limit for small earthquakes close to home, because a 4.0 three hundred kilometres away and a 3.0 under your building are not the same event.
NOTIFICATIONS
Alerts arrive only for earthquakes that match the area you chose and the magnitude you set.
You can set a separate limit for large earthquakes, so the ones that really matter stand apart.
The first alert for a possibly felt tremor keeps updating while the event develops. It is rewritten when the magnitude lands, when the epicentre moves, and when an agency reviews the solution.
Overnight, only earthquakes above the threshold you set will wake you.
Every alert that reaches you is saved to a history you can go back through.
The live card on your Lock Screen updates itself as the event develops.
WHAT IS ACTUALLY KNOWN ABOUT AN EARTHQUAKE
Sismy does not reduce an earthquake to one number.
You can see the shaking each seismometer recorded, station by station.
You can see the felt reports people sent in, and see how far the shaking carried.
It explains how the fault broke, in plain language.
It lists the aftershocks, and past earthquakes of similar size in the same place.
MAP
The map shows fault lines worldwide, earthquake density and shaking intensity layers. One tap opens the epicentre full screen.
WHERE THE DATA COMES FROM
The data comes from EMSC, USGS ShakeMap, ORFEUS RRSM and regional agencies. Every measurement is shown next to the agency that produced it.
IMPORTANT
Sismy is not an early warning system. It cannot tell you before the shaking reaches you. It sends a notification after an earthquake has happened and seismic networks have detected it. In an emergency, follow the instructions of the official disaster authority where you are.
Sismy is free and shows ads. You can remove them from inside the app.
