Where Our Data Comes From

United States Geological Survey (USGS)

The USGS is a scientific agency of the United States government that provides reliable scientific information about the Earth, its natural resources, and natural hazards. Their earthquake monitoring network is one of the most comprehensive in the world, providing:

• Real-time earthquake detection and location
• Magnitude calculations
• Depth measurements
• Geographic coordinates
• Detailed location descriptions

We access this data through their public API, which provides near real-time earthquake information from around the globe.

Data Processing

To ensure the highest quality of information for our users, we apply several processing steps to the raw data:

• Data validation and error checking
• Normalization of magnitude formats
• Location name standardization
• Timestamp conversion to local time zones
• Filtering of duplicate or erroneous entries

Update Frequency

We update our database every 2 minutes to ensure you have access to the most current earthquake information. This interval balances the need for timely updates with system stability and data accuracy.

Data Accuracy

While we strive to provide the most accurate information possible, it's important to note that earthquake data, especially in the immediate aftermath of an event, may be subject to revision. Magnitudes and locations may be adjusted as more data becomes available.
