The new geophysical technique enhances imaging of fluid-filled rocks by utilizing advanced seismic imaging methods. By analyzing seismic waves and their propagation through the Earth, scientists can identify areas with fluid-filled rock formations. This technique provides higher-resolution images of subsurface structures, offering insights into the distribution and characteristics of these fluid-filled rocks. Additionally, correlating the imaging data with microearthquakes helps identify regions where fluid movement within rocks may trigger seismic activity, contributing to a better understanding of geological processes and potential seismic hazards.
