Live Map

Live shows earthquake detection on a map as it happens. It has two modes:

  • Live follows your project's stations and their real detections.
  • Simulation plays a made-up earthquake on a demonstration network, so you can see how detection works.

Live map in Grillo Cloud

What the map shows​

  • Your stations, with their online status
  • Cities and fault lines
  • During an event: the stations that have detected it, the located epicenter, and expanding P-wave and S-wave fronts
  • Estimated damage zones around the epicenter, from Minor to Severe

The Legend explains each symbol.

Live mode​

The Live button shows whether the map is connected to earthquake detection: Connected, Connecting, or Disconnected. If it stays disconnected, refresh the page.

When stations start detecting shaking, each pick plays a short beep and the Event Log lists the pick. Once at least four stations have picked, Grillo Cloud locates the event and the map shows its magnitude, epicenter, and the cities the waves will reach.

Map settings​

Open Map Settings to choose:

  • Minimum Magnitude — ignore events smaller than this
  • Auto-zoom to epicenter — move the map to each new event
  • Alert Sound — the sound played when an event is detected: Earthquake or Tone

Browsers block audio until you have interacted with the page. Click anywhere on the page after opening it if you rely on the sound.

Simulation mode​

Switch to Simulation and select Simulate Earthquake. The map generates an earthquake, shows simulated station picks, locates the event, and animates the waves.

A simulated earthquake on the live map: stations detect it, the event is located, and the P-wave and S-wave fronts spread out while panels show the magnitude, estimated arrival times, and affected cities

:::danger Simulation is not real data Simulation mode uses a demonstration station set, not your sensors. Check which mode is selected before acting on anything shown on this page. :::

Limits​

The live map is a monitoring view for your team. It does not send SMS, email, or mobile alerts, and it is not a public warning service. See Earthquake Early Warning for what warning time is physically possible.
