Comprehensive Tracking Gives Timely Cautions of Volcano Rekindling
Scientists must employ numerous tools to listen to and see activity inside a volcano in order to keep a watch on it. The USGS Volcano Hazards Program monitors volcanoes for signals of change that indicate volcanic reawakening. Surveillance must include several observations (earthquakes, ground activity, volcanic gas, rock chemistry, water chemistry, remote satellite analysis) on a continuous or near-real-time basis in order to understand a volcano’s behavior.
Broad networks of many instruments result in a much fuller image of volcanic activity
Researchers collect data from instrument networks and evaluate it to look for unusual signals. Volcanologists can better forecast changes in volcanic activity and decide whether and when a volcano may erupt in the future by comparing the data evaluation with similar outcomes from previous volcanic events. The majority of information is available through our offices in the observatories. Visits to the volcanoes, on the other hand, give valuable information.

Rapid technological advancements are assisting scientists in developing efficient and precise monitoring equipment. These cutting-edge devices can capture and transmit precise real-time data from the volcano to the Observatory offices, improving eruption prediction. Instruments must be put during peaceful periods when volcanoes are not active to ensure that they are ready to detect even the slightest volcanic stirring. Early detection allows people to prepare for an eruption as much as possible.

When a volcano begins to exhibit new or unexpected activity indications, monitoring data aids in answering crucial questions required for analyzing and conveying timely information about volcanic risks. For example, prior to Mount St. Helens’ 2004 eruption, monitoring equipment data revealed a significant increase in earthquake activity.
Investigators quickly reviewed other monitoring data, such as gas, ground deformation, and satellite photos, to determine whether lava or fluid was moving to the surface. Scientists were able to define the types of magma that could be flowing towards the surface based on the volcano’s history and the analysis of monitoring data. This type of knowledge aids scientists in determining the various forms of volcanic activity and the accompanying risks to people. Recognizing the hazards assists authorities in determining which real-time precautions are required to prevent loss of life and property.
