Three events that might signal a volcanic eruption are changes in earthquake activity, volcano surface bulges, and increased gas emissions. These changes can indicate rising magma beneath the surface, which may lead to an eruption.
Signs of an impending volcanic eruption can include increased seismic activity, changes in gas emissions, ground deformation or swelling, and changes in the appearance of the volcano such as increased steaming or thermal activity. Monitoring these signs can help scientists predict and warn of a potential eruption.
Instruments used to predict eruptions include seismometers to detect earthquake activity, gas analyzers to monitor changes in gas emissions, thermal cameras to detect changes in temperature, and GPS sensors to measure ground deformation. These data are used by scientists to monitor volcanic activity and assess the likelihood of an eruption.
The Long Valley Caldera is still considered an active volcanic area, as it has experienced ongoing seismic activity and the release of volcanic gases. While there is no imminent threat of an eruption, monitoring of the caldera continues to track any potential changes that may indicate increased volcanic activity.
An example of a sudden geologic process is a volcanic eruption. These events can release massive amounts of lava, ash, and gases in a short period, causing rapid changes to the landscape and environment.
Some instruments and technology used to study active volcanoes include seismometers to monitor earthquake activity, gas sensors to measure volcanic gases, satellite imagery to track changes in surface temperature and topography, and drones for aerial surveys to monitor volcanic activity up close. These tools help scientists gather data to better understand and predict volcanic eruptions.
Signs of an imminent volcanic eruption include increased earthquake activity, swelling of the volcanic cone, increased gas emissions, and changes in the composition of gas emissions. Monitoring these signs can help predict and warn of an eruption.

Increased seismic activity such as earthquakes. Eruption of lava, ash, and gases. Ground deformation or changes in ground temperature.
This is known as an earthquake or as seismic activity.
Increased earthquake activity: Swarms of small earthquakes may occur as magma rises toward the surface. Steam or gas emissions: An increase in steam or gas emissions, often accompanied by a strong sulfur smell, may indicate a volcano is becoming more active. Ground deformation: Changes in the shape of the volcano, such as swelling or bulging, can signal that magma is moving beneath the surface and may lead to an eruption.

Seismographs record seismic activity in volcanic regions as predictors of volcanic activity. Additionally, GPS instruments record the rise and fall in surface features which may indicate a possible building of magmatic pressure underground.
