The US Geological Survey uses a nationwide volcano alert system to categorize volcanoes into 4 warning levels- Normal, Advisory, Watch, and Warning. They are used to notify the public about the likelihood of an eruption.
Scientists are monitoring a stratovolcano that is currently labeled with a WATCH warning level. Their data from the past 3 months is shown in the photos.
The team must decide whether to change the current warning level. What should they do?
a)
They should raise the warning level to Warning. The data shows that the volcanic activity is increasing.
b)
They should lower the warning level to Advisory. The data shows that the volcanic activity is decreasing.
