Deformation Sensors
Design Considerations
•Mechanism (sliding, toppling, combination)
•Redundancy
•Robustness
All of the current instrumentation is situated on the South Peak of the mountain around the network of deep fissures.  The layout was designed to allow to aid in the determination of the movement mechanism (either sliding, toppling or a combination of the two), to provide redundancy (overlapping series of different sensors so that movement could be verified across various sensor types) and to be robust (with stand significant climatic influences and vandalism)
