TomK,
Seems I need to treat you as a student here.
Approximately 10k naturally occuring µ- will strike a m² area per minute laying flat on the ground, approximately 1,250 µ- per minute when the m² area is turned semi perpendicular as would be neccesary for imaging a volcano. This means the exposure time for imagery data collection of a volcano using naturally occuring µ- is considerably long, months. Now that's all fine and dandy when simply wanting to map a magma reservoir within a volcano. The moment one wants to use the technique as an early warning system for eruptions in highly active volcanos such as Kilauea or Mauna Loa, the technique becomes fairly inadiquate due to the neccesary imagery exposure times.
Data collection frames and their shortcomings.
Consider a strobe light as an example. If we were in a dark room with a strobe light set to 1 flash per second and we were tossing balls to one another, what would happen to our ability to predict where and when a ball was thrown to us personally and would we be able to catch the ball that was thown to us or would it likely hit us in the face or body before we were able to predict where to put our hands to catch it?
As we decrease the time between strobe flashes, our predictive/deductive ability to catch a thrown ball begins to increase and we become more successful at catching the ball.
The same applies to using muon tomography when attempting to use it as an early warning system for volcanic eruption.
It's one thing to use cosmic-ray muon tomography for mapping a magma reservoir and very much another to use it as an early warning system for highly active volcanos.
This is why I have stated that using artificially created muons in the form of highly concentrated muon beams would be far more likely capable of being used to produce an early warning system for volcanic eruptions. Using such techniques, several volcanic maps a day could be created, ultimately becoming more effective at becoming an early warning system.
As per your reply, I can only deduce that you didn't understand a damn thing that was being discussed.
