GWN Global Earth Monitor
v1.1.0 Download
Real-time planetary monitoring

Watch the planet
in real time.

GWN — Global Earth Monitor is a desktop application that fuses live earthquake, fireball, asteroid, volcano, atmosphere, and space weather feeds into one window. Built on Electron, Leaflet, and real public data from USGS, NASA, EMSC, and dozens of FDSN stations.

// Features

Everything Earth, in one window.

Ten live data layers, an interactive 3D solar system, real seismic waveforms, and a statistics workspace — all without leaving the app.

Real-time Earthquake Feed

Live data from USGS, EMSC, JMA, ISC, and more with magnitude filtering, auto-refresh, and interactive maps.

Fireball Tracking

NASA fireball and bolide event overlays plotted alongside other planetary activity.

Asteroid Monitor

Near-Earth asteroid data from NASA JPL — close-approach details and Pan-STARRS sky imagery.

Sky Explorer

Pan-STARRS DR2 sky survey browser with 3 billion objects, color composites, and deep-sky presets.

3D Solar System Simulation

Interactive asteroid orbits powered by Asterank, MPC, and Kepler data.

Volcano Activity

Live volcano alerts and eruption data from the Smithsonian Global Volcanism Program.

Atmosphere Layer

Weather overlays, SO₂, UV Aerosol Index, thermal anomalies, and space weather from NOAA SWPC.

Prediction Center

Seismic prediction tools and an analysis workspace for deeper review.

Seismic Stations

Browse global seismograph networks, select stations, and view live MiniSEED waveforms with audio feedback.

Statistics Workspace

Filter and compare earthquake feeds by source, magnitude, depth, and cadence.

Collapsible Waveform Drawer

Station waveform panel collapses to a slim bar so the map keeps the spotlight, and expands back without losing your session.

Notes & Workspace

Capture observations, link to the data you're seeing, and keep them across sessions in a dedicated Notes tab.

// In the app

Live data, mapped.

Earthquakes, magnitudes, and depth — all colour-coded and refreshable from the side panel.

// Install

Two ways to install.

Either grab the Windows installer from GitHub Releases, or run a one-line command in PowerShell. Both end up with the same app in your Start menu.

Option 1 · GitHub Release

Download the Windows installer

Grab the latest signed Windows installer from the Releases page. It's a normal NSIS setup — picks an install folder, drops Start menu and desktop shortcuts, registers an uninstaller in Apps & features.

  1. Open the latest release on GitHub
  2. Download GWN-Setup-<version>.exe
  3. Run it and finish the wizard
  4. Launch GWN — Global Earth Monitor from the Start menu
Download v1.1.0
Option 2 · PowerShell

One-line command install

From PowerShell, this downloads install.ps1 from the main branch and runs it. The script fetches the same Windows setup and launches it. Works from PowerShell, Run dialog, or Command Prompt.

  1. Open PowerShell
  2. Paste the command below
  3. Confirm the UAC prompt to run the installer
  4. Launch GWN from the Start menu
irm https://raw.githubusercontent.com/tattooinmtl/GWN-GlobalEarthMonitor/main/install.ps1 | iex
powershell -NoProfile -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/tattooinmtl/GWN-GlobalEarthMonitor/main/install.ps1 | iex"

To build from source instead of using the published setup, run with $env:GWN_INSTALL_MODE = 'source' in front of the same command (requires Node.js 18+).
