EarthQuake Tracker

Why wait for news alerts when your phone can show you seismic activity in real time?

EarthQuake Tracker turns your device into a personal seismic monitoring station. Whether you live in a tectonically active region, travel frequently, or simply want to stay informed, this app delivers live earthquake data directly to your screen. It replaces the uncertainty of waiting for broadcast alerts with a clear, interactive map that updates as events happen.

Core functionality and data tools

The app pulls its information from global seismic networks, including USGS and EMSC feeds. These data streams are processed and displayed on an interactive map that supports pinch-to-zoom, pan, and layer toggling. Each earthquake event appears as a color-coded marker that indicates magnitude range — from minor tremors (M1.0–2.9) to major quakes (M6.0+). Tapping any marker reveals a detail card containing:

• Exact epicenter coordinates (latitude/longitude)
• Reported magnitude (Richter scale value)
• Depth in kilometers below the surface
• Timestamp in both UTC and your local timezone
• Distance from your current GPS location (calculated automatically)

A dedicated list view complements the map. Events are sorted by recency or magnitude, and each row shows the key data points at a glance. You can filter this list by minimum magnitude threshold, date range, or geographic region. The search function lets you look up historical events by location name or date, making it useful for research or post-event analysis.

Notification and alert system

Configure push notifications to match your personal risk tolerance. The alert engine lets you set a minimum magnitude threshold — for example, ignore everything below M3.0, but get an immediate notification for M4.5 and above. You can also define a notification radius: only receive alerts for quakes within 50, 100, or 200 kilometers of your current location. When a qualifying event is detected, the notification includes the magnitude, approximate location, and a link to open the detail view.

Visual customization and map layers

The map interface supports multiple base layers, including standard terrain, satellite imagery, and a dark mode option for low-light use. You can overlay tectonic plate boundaries or fault lines to better understand the geological context of recent activity. The app also provides a heatmap mode that visualizes recent seismic density across a region, helping you spot clusters of activity that might indicate foreshocks or aftershock sequences.

Key advantages

• Live data from major seismic networks with automatic refresh
• Customizable notification filters for magnitude and distance
• Interactive map with multiple base layers and fault overlays
• Historical search and filter tools for research or reference
• Low-bandwidth operation — uses minimal data for text-based event details

Consider downloading EarthQuake Tracker

If staying informed about seismic activity matters to you — whether for personal safety, curiosity, or travel planning — this app provides a straightforward, data-driven way to monitor earthquakes as they happen.

Heads up: you'll need wifi or mobile data for live updates and map tiles. The basic notification system works offline once configured, but full map interactivity and event details require an internet connection. Some advanced features, such as ad-free usage or extended historical archives, are available as optional in-app purchases.
