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
