# Seismic-Tsunami Event Linkage

The **Seismic-Tsunami Event Linkage** is a comprehensive, machine learning-ready dataset. It contains seismic characteristics and tsunami potential indicators for 782 significant earthquakes recorded globally from 2001 to 2022. This dataset has been specifically processed and structured for applications in tsunami risk prediction, earthquake analysis, and seismic hazard assessment. It is an enhanced version derived from the foundational "Earthquake Dataset" on Kaggle, optimized for robust binary classification tasks.

## Data Information

- **Total Records**: 782 earthquakes
- **Time Period**: January 1, 2001 to December 31, 2022 (22 years)
- **Geographic Coverage**: Global (Latitude: -61.85° to 71.63°, Longitude: -179.97° to 179.66°)
- **File Format**: CSV
- **Missing Values**: None (100% complete)
- **Target Variable**: `tsunami` (binary classification: 1 for tsunami potential, 0 for non-tsunami)

## Key Features

1. **Tsunami Classification**
  - **Non-Tsunami Events**: 478 records (61.1%)
  - **Tsunami-Potential Events**: 304 records (38.9%)
  - A well-balanced dataset suitable for binary classification tasks.

2. **Seismic Magnitude Distribution**
  - **Range**: 6.5 - 9.1 on the Richter scale
  - **Mean Magnitude**: 6.94
  - **Major Earthquakes (≥8.0)**: Includes 28 events, such as the 2004 (9.1) and 2011 (9.1) mega-earthquakes.
