How Fast Do Gases From Volcanic Eruptions Travel?
ES0906  Measure Sulfur Dioxide Distance

Here's a static image showing the location of the SO2 cloud five days after the main eruption.

  !   Use the ruler tool to measure the distance the leading edge of the cloud has traveled.



7. Use the distance the SO2 gas traveled and the time since the eruption to calculate its speed in km/hr. Show your work.
