The Earth
never
sits still.
Seismoscope streams every earthquake on the planet to your pocket — magnitudes, depths, shake maps and waveforms, minutes after the ground moves.
A seismology lab
that fits in your hand
Every catalogued event from M 1 microquakes to great earthquakes, streamed from networks worldwide.
Tap any quake to scrub the actual seismogram — watch P and S waves arrive station by station.
Set a magnitude floor and a radius around the places you care about. Nothing else buzzes.
Report shaking in two taps and see your dot appear on the community intensity map.
An M 7 packs about a thousand M 5s.
Seismoscope shows both arrivals on every trace.
Earth data only in the app. For now.
Questions, answered
Is Seismoscope really free?
Yes — free on both stores, no account, no ads, no in-app purchases. The data is public and so is the app.
Where does the earthquake data come from?
Public seismic networks aggregated by agencies like the USGS — thousands of stations reporting worldwide. See Data sources in the footer for the full list.
Will it warn me before shaking starts?
No. Seismoscope reports quakes minutes after they are catalogued — it is not an early-warning system, and alerts should never be your safety plan.
Why didn’t I see the quake I just felt?
Small local events can take a while to be reviewed and published, and very small ones may fall under your feed’s magnitude floor. Try lowering the floor in Alerts.
Does it drain my battery?
No — the app pulls a compact feed on a schedule rather than holding a connection open. Alerts arrive as ordinary push notifications.
Feel it before the news does.
Free on both stores. No account, no ads — just the planet, live.
