Earthquake and Volcanic Activity Quiz

What can thermal imaging cameras indicate when monitoring a volcano?

• The presence of gas emissions

• Hotspots and thermal anomalies suggesting volcanic unrest

• The exact time an eruption will occur

• The amount of ash released during an eruption

What kind of data do gas sensors monitor around volcanoes?

• Temperature changes

• Seismic waves

• Gas emissions like sulfur dioxide and carbon dioxide

• Visual changes in the landscape

How do GPS stations contribute to earthquake monitoring?

• By capturing high-resolution images of the Earth's surface

• By measuring tiny changes in the Earth's surface elevation or movement

• By recording the speed of seismic waves

• By detecting thermal anomalies on the Earth's surface

What is the primary function of a seismometer?

• To predict the exact time an earthquake will occur

• To measure ground motion caused by seismic waves

• To record the temperature changes on the Earth's surface

• To detect changes in gas emissions from volcanoes

What role does satellite imaging play in monitoring earthquakes?

• It measures ground deformation and surface ruptures

• It directly measures seismic wave intensity

• It predicts the timing of an earthquake

• It detects thermal anomalies only

How do scientists use the data from various monitoring methods?

• To predict weather conditions

• To gain a comprehensive understanding of seismic and volcanic activity

• To measure the depth of the Earth's core

• To monitor underwater animal movements

What is the difference between a seismograph and a seismometer?

• A seismograph measures gas emissions; a seismometer does not.

• A seismograph records ground motion; a seismometer measures any ground motion.

• A seismometer captures images; a seismograph does not.

• There is no difference; they are the same device.

What is the goal of integrating data from different monitoring methods?

• To increase the cost of monitoring

• To provide more accurate predictions and timely warnings

• To create a global positioning system

• To monitor the health of marine life near volcanic islands

What do thermal imaging cameras detect?

• Changes in gas emissions

• Infrared radiation emitted by objects

• Ground deformation and displacement

• Seismic waves and vibrations

Which of the following is NOT a challenge in predicting earthquakes and volcanic eruptions?

• The inability to cover all prone areas with monitoring networks

• The complexity of interactions between geological structures

• The ease of determining the exact timing of an event

• The potential for false alarms leading to public distrust
