Updated 15:52, 27 October 2026

Felt a tremor? Epicentro tells you where, how strong and what it means for you.

INGV, USGS and EMSC data explained in plain words by an AI, the estimated intensity at your home and an emergency mode that works even without a network.

  • Where, how strong, how far
  • Estimated intensity in your town
  • Source and time next to every figure

The bed shakes. Now what?

In the first minutes, different numbers and unverified news circulate. Epicentro shows only what the sources have published, with the time next to it.

01

Where was it?

Epicentre and depth on a map you read at a glance, with the nearest town.

02

How strong was it?

Magnitude, estimated intensity in your town and what it means in practice.

03

How far is it from me?

Distance from your town and the areas you follow, already calculated.

An AI that explains what happened, in plain words.

For every quake you see the source data and, in a separate box, a clear explanation: how it felt, whether it is normal for that area, what to expect in the hours after. Pick an example and watch it write.

  • Always labelled as AI, never mixed up with the official figure
  • In your language, out of seven
  • With Plus you can also ask questions, such as “is my home at risk?”

Explanation written by an AI

A light quake, only 3 km deep. Near the epicentre many people felt it as a sharp jolt or a short vibration. Quakes of this size rarely cause damage. Smaller aftershocks may follow in the next hours.

It may contain errors: when in doubt, the source figure prevails.

Illustrative examples. In the app the explanation comes with every quake, in your language.

How strong it was at your home, not just at the epicentre.

Magnitude is a single number; intensity changes with distance. Epicentro estimates how much the ground shook where you are and shows your town's seismic zone. Move the sliders and see the difference.

  • Computed for your home and the areas you follow
  • Seismic zone of 8,009 towns, offline too
  • An indicative estimate, never passed off as an official survey
M 3.2
12 km

Indicative estimate using an empirical attenuation relation and an 8 km depth: it does not replace official surveys. In the app it is computed for your home and the areas you follow.

Some people indoors feel a light vibration.

When the network drops, the guide stays.

  • Assembly areas and hospitals from OpenStreetMap

Connected. The guide is already saved on your phone.
  1. Protect yourselfUnder a sturdy table or next to a load-bearing wall, away from glass. Wait until it stops.
  2. Stay still for 30 secondsAftershocks can come right after. Do not use the lift.
  3. Check gas, water and powerIf you smell gas, shut the meter and do not light flames.
  4. Leave if the building is damagedClosed shoes, documents and phone. Take the stairs.
  5. Go to the assembly areaFollow your town's plan: the app shows the nearest one.

Illustrative example: in the app you see real data.

Epicentro Network: phones as seismic sensors.

An optional experiment. A phone that is still and charging can pick up the first waves and send an anonymous signal; the server compares it with nearby phones and discards isolated signals, such as a dropped phone. Today it sends no alerts, and we say so plainly.

Every quake shows its source and update time. If the source revises a figure, you see it change with the note “Subject to revision”.

What the app does not do

  • It is not a Civil Protection app and is not part of INGV.
  • It does not predict earthquakes: it shows what happened, plus statistical estimates that are not predictions.
  • It does not replace guidance from the authorities.
  • It does not guarantee timing: data arrives when the sources publish it.

Quick answers

The most asked questions. The rest are on the FAQ page.

No. It is an independent service: it is not part of Civil Protection or INGV. For official guidance follow the authorities and, in an emergency, call 112.

No, and no service can. Epicentro shows what happened when the sources publish it, plus statistical estimates, such as estimated intensity and, with Epicentro Plus, aftershock probability, that are not predictions.

From INGV for Italy, USGS for the rest of the world and EMSC as a backup. Next to every figure you find the source and time, and you can see if it was revised.

It depends on when the source publishes the event and how your phone delivers the notification. The alert arrives after the quake, never before, and can be delayed.

The core is free and works without an account: basic alerts, events, map, summary and “I felt it”. Plus is optional; price and free trial are as shown by the store.
