An increase in gas emissions from a volcano can indicate that magma is on the move, which may lead to an eruption. If gas emissions stop or decrease it can be a sign that activity is decreasing or that pressure is building for an explosive eruption.

How are gas emissions used for predicting eruptions?
An increase in gas emissions from a volcano can indicate that magma is on the move, which may lead to an eruption. If gas emissions stop or decrease it can be a sign that activity is decreasing or that pressure is building for an explosive eruption.
What are instruments used to predict eruptions?
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.
What is the name of the top pit of the volcano?
The top pit of a volcano is called the crater. It is the opening at the summit of the volcano where volcanic activity such as eruptions and gas emissions occur.
What three variables do scientists monitor when attempting to forecast volcanic eruptions?
Scientists monitor volcanic earthquakes, ground deformation, and gas emissions when attempting to forecast volcanic eruptions. Changes in these variables can provide critical information about the state of a volcano and help predict the likelihood of an eruption.
How does plate tectonics affect global warming?
it affect global warming due to emissions sent from volcanic eruptions and multiple other emissions `
What is the behavior of the volcano?
The behavior of a volcano can vary widely depending on its type and current geological activity. It may exhibit explosive eruptions, characterized by the violent release of gas and ash, or effusive eruptions, where lava flows steadily from the vent. Other behaviors include gas emissions, ground deformation, and seismic activity, which can indicate potential eruptions. Monitoring these signs helps scientists predict volcanic activity and assess potential hazards.
When did Mt Bromo last erupt?
The last known eruption of Mount Bromo in Indonesia occurred in 2016. The volcano has been relatively active in recent years with small eruptions and emissions of ash and gas.
How are volcanoes measured and monitored for potential eruptions?
Volcanoes are measured and monitored using various tools and techniques such as seismometers to detect earthquakes, gas sensors to monitor emissions, and satellite imagery to track changes in the volcano's surface. Scientists also study the volcano's history and behavior to predict potential eruptions.
How does ethanol reduce greenhouse gas emissions?
Ethanol reduces greenhouse gas emissions by producing less carbon dioxide when burned compared to traditional gasoline. This is because ethanol is made from plants that absorb carbon dioxide during growth, offsetting the emissions produced when it is used as fuel.
What is ethanol gas used for in the automotive industry?
Ethanol gas is used as a fuel additive in the automotive industry to increase octane levels and reduce emissions in gasoline-powered vehicles.
Which gas is not produced by volcanic eruptions?
oxygen
What do we monitor about volcanoes to predict eruptions?
In order to try to predict a volcanic eruption, scientists monitor the distribution of earthquakes near the volcano, the quantity, temperature, and composition of gas emissions, and look for deformation of the volcano itself. All of these can be used to determine if magma is moving underground, how close it is to the surface, and even how obstructed it is.
