Volcanic activity is the study of volcanic eruptions, lava flows, and other related phenomena that occur in volcanic regions. It involves the monitoring, study, and prediction of volcanic events to better understand the geological processes that occur beneath the Earth's surface. Researchers in this field use a variety of techniques such as remote sensing, seismic monitoring, gas emission measurements, and geophysical surveys to study volcanic activity and assess the potential hazards it poses to people and the environment. Understanding volcanic activity is crucial for ensuring the safety of communities living near active volcanoes and for developing strategies to mitigate the risks associated with volcanic eruptions.
