J. 100,000 km^3- Assume that a volcano with a diameter of 30 km erupted 500,000 years ago. If the time that elapses between eruptions is equal to the
average amount of time given in Figure 2, the volcano should erupt approximately:
A. 250,000 years from now.
B. 500,000 years from now.
C. 1,000,000 years from now.
D. 1,500,000 years from now.
