# Earthquake Detection

On the Seismic and Enterprise [plans](/dashboard/plans), Grillo Cloud detects earthquakes from your sensors' data automatically.

You get:

- **An automatic event catalog.** Each detected earthquake is recorded with its time, location, depth, and magnitude.
- **A live map.** Watch detections as they happen, with the stations that triggered and the estimated wave fronts, or run a simulation.
- **In-app alerts.** Grillo Cloud shows a notification and an unread count on **Events** when a new earthquake is detected.

Events and the live map appear in the **Seismic** group of the sidebar. Detected events are also available from the [Data API](/dashboard/data/api#events).

## Requirements

- A project on the Seismic or Enterprise plan. [Contact Grillo](/support/contact) to change plan.
- Sensors recording continuously and sending their data to Grillo. Detection does not run on [triggered recordings](/dashboard/sensors/recording-mode) or on data that goes to [your own server](/dashboard/data/data-server).
- Enough stations, spread around the area you want to monitor. An event is only published once at least four stations have detected it. See [How Detection Works](/events/how-detection-works).

:::warning Not a public warning service
Detected events are automatic estimates. They do not replace instructions from emergency services or an official earthquake-warning authority.
