Seismic Data

Digital recordings and measurements of seismic waves that provide crucial information about Earth's subsurface structure, composition, and tectonic activity.

Overview

Seismic data consists of recorded measurements of seismic waves propagating through the Earth, captured using specialized equipment like geophones and seismometers. This data forms the foundation of modern geophysical exploration and earthquake monitoring.
