What is the device used to predict volcanoes?
A seismometer is commonly used to predict volcanic eruptions. It measures the seismic activity below the surface, which can indicate movement of magma and potential volcanic activity. Other devices like tiltmeters and gas sensors are also used to monitor changes in volcanic activity.
What was the Krakatoa eruption on the Richter scale?
The Krakatoa eruption in 1883 is estimated to have been around 6 to 7 on the Volcanic Explosivity Index (VEI), which is used to measure the intensity of volcanic eruptions. The Richter scale, which measures the magnitude of earthquakes, is not typically used to measure volcanic eruptions.
What are tephra layers?
Tephra layers are deposits of volcanic ash and fragments that accumulate as a result of volcanic eruptions. They are sorted by size and composition, creating distinct layers that can be used to date and correlate geologic events. Tephra layers are important for understanding volcanic activity and reconstructing past eruptions.
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.
What the 1951 eruption of Mount Lamington register on the Richter Scale?
The 1951 eruption of Mount Lamington in Papua New Guinea was estimated to have a Volcanic Explosivity Index (VEI) of 4. The Richter Scale is not typically used to measure the size of volcanic eruptions; instead, the VEI is commonly used to classify and compare the explosiveness of volcanic eruptions.

What instruments or technology are used to study active volcanic?
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.
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 molten rock used for after when erupted?
There is no use for molten rock from volcanic eruptions.
What is a seismograph for?
They are used to measure earthquakes and volcanic eruptions by recording seismic activity.

How do volcanologists predict eruptions?
Well the have equipment that helps them, but they look around volcanos to see if they have any sign of erupting.
What are vibrations that travel through the ground?
Seismic waves are vibrations that travel through the ground. These waves are generated by earthquakes, volcanic eruptions, and explosions. Seismic waves are used to study the Earth's interior and monitor natural hazards.
What are two ways that a volcanic eruption can benefit people?
Two ways that volcanic eruption can benefit people include the creation of land mass and of energy. Volcanic steam and heat can be used to produce energy.
