Earthquake Detection and Analysis

Earthquake Detection and Analysis is a research topic within Geophysics. Science Explorer counts 39k research works in it since 1950. 14.0% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the study of various phenomena that may serve as potential earthquake precursors, including ionospheric anomalies, seismic electromagnetics, pre-earthquake signals, thermal infrared emission, lithosphere-atmosphere-ionosphere coupling, electromagnetic radiation, and geoelectric potential changes. The research also involves monitoring seismic activity and developing earthquake prediction models.
