Role of radon as a precursor to earthquakes:An appraisal

TL;DR

This paper reviews the potential of radon monitoring as a precursor to earthquakes, discussing recent findings, anomalies observed, and future directions, with a focus on the Himalayan region.

Contribution

It provides a comprehensive appraisal of radon as an earthquake precursor, including recent studies and future perspectives in radon estimation techniques.

Findings

Radon levels show anomalies before seismic events.

Strain changes in the earth's surface influence radon emission.

Recent Himalayan studies support radon as a seismic precursor.

Abstract

Radon monitoring has recently gained extensive attention among seismologists. It is now widely reported as a precursssory signal prior to occurrence of a seismic event. The enhanced estimation of radon in soil gas is basically attributed to the strain changes which arise within the earth surface. In this chapter, the role of radon as a precurssor is eleborated, acompanied by the anomalies which come across during observation. Additionally, the recent studies done in Himalayan Belt is also reviewd along with future perspectives in radon estimation.
