Each record represents a single seismic event (primarily earthquakes) and contains detailed information, including: 1. **Event Time & Location**: Precise timestamp, geographic coordinates (`latitude`, `longitude`), and depth of the event. 2. **Magnitude**: The magnitude of the event (`mag`) and the method used to calculate it (`magType`), such as `md`, `ml`, or `mww`. 3. **Data Quality**: Metrics such as root mean square (`rms`) of travel-time residuals, azimuthal gap (`gap`), and measurement errors to assess the reliability of the data. 4. **Source Information**: Details about the network (`net`) that reported the event and a unique event ID.
