Volcano Monitoring Quiz

What is seismic monitoring of volcanic activity?

• Use of seismometers to detect and record seismic waves produced by volcanic processes.

• Measuring the temperature of lava flows

• Using satellites to monitor volcanic eruptions

• Analyzing the chemical composition of volcanic rocks

How do seismologists use seismic waves to monitor volcanic activity?

• By counting to ten and seeing how many earthquakes occur

• By observing the color of the volcanic ash

• By measuring the temperature of the lava

• By analyzing the frequency, amplitude, and direction of the waves to detect changes in the volcano's behavior.

Why is monitoring gas emissions from volcanoes important?

• To create new energy sources

• To provide entertainment for tourists

• To predict volcanic eruptions and protect nearby communities.

• To increase global warming

What are the common gases emitted by volcanoes and how are they monitored? BONUS QUESTION-

• Carbon monoxide, nitrogen dioxide, and ozone

• Water vapor, carbon dioxide, sulfur dioxide, hydrogen sulfide, and hydrogen chloride

• Helium, neon, krypton, and xenon

• Oxygen, nitrogen, argon, and methane

How can satellite imagery and tiltmeters be used to monitor volcanic activity?

• By counting the number of trees around the volcano

• By analyzing the types of rocks found near the volcano

• By measuring the acidity of the surrounding water

• By capturing changes in the shape, inflation rate, and gas emissions of the volcano.

What is ground deformation/inflation monitoring using GPS?

• Monitoring changes in the ocean floor using GPS technology to predict tsunamis.

• Using GPS to track changes in the atmosphere due to climate change.

• Measuring changes in the Earth's surface using GPS technology to monitor for volcanic activity.

• Measuring changes in the Earth's surface using GPS technology to monitor for earthquakes.

How does seismometers/seismograms help in detecting ground movement near a volcano?

• By analyzing the color of the lava

• By measuring the frequency and intensity of shaking near the volcanoes

• By counting the number of earthquakes in the area

• By using a barometer to measure air pressure

How can a UV Spectrometer on plane be used to detect volcanic eruptions?

• By analyzing the color of the lava

• By measuring the light absorbed in a gas plume

• By monitoring the low-frequency sound waves produced by the movement of magma and gas within the volcano.

• By observing the behavior of local wildlife
