## What is EarthAlert?

EarthAlert delivers real-time earthquake notifications filtered exactly to your location and magnitude preferences — no more waking up to alerts from hundreds of miles away.

Why EarthAlert?

Most earthquake apps bombard you with every tremor worldwide. EarthAlert lets you set your own distance radius and minimum magnitude, so you only get alerts that actually matter to you.

Key Features:

• Smart Distance Filter — Set a custom radius (50–1000 km) around your location. Only earthquakes within your zone trigger alerts.
• Magnitude Control — Filter by minimum magnitude (M1.0–M7.0). Skip the micro-tremors, catch the ones that count.
• 24h or 7-Day View — Switch between the last 24 hours and the past 7 days at a tap.
• I Felt It — Experienced a quake? Report it directly to the USGS with one tap from the detail screen.
• Real-Time Data — Powered by the USGS Earthquake Hazards Program, the world's most trusted seismic data source.
• Clean Design — Dark interface designed for quick, at-a-glance information. Color-coded magnitude badges (green to red) let you assess severity instantly.
• Miles or Kilometers — Display distances in whatever unit feels natural.

Data Source

All earthquake data is provided by the U.S. Geological Survey (USGS), updated in near real-time.
