Question

Refer to MAPS for this question by following this link: http://www.mapwatch.com/gallery/volcanic-hazard-map.shtml This is a hazard prediction map and a hazard map of eruptive materials for Mount Rainier (Note: dates from 199 1) A. Which material(s) is(are) restricted to within a 20-30 km region around the summit? B. Which material is likely found at greatest distance from the summit? C. At what distance is the outer exte Mount Rainier? nt of the most distant lahar (mudflow) deposit on land from the summit cf What is the annual probability of ash fall of 10 cm or greater, in the Mount Rainier region'? (Note: check this link (http:/ df) E. What is the annual probability of ash fall of 1 cm in the Mount Rainier region? F. What large city is likely to be impacted by an eruption of Mount Rainier? G. W hat is the likely impact on this city - that is, what geologic hazard or hazards are most likely to impact? What information did the hazard map-makers use to determine the possible hazards and their extent (there are several likely)? H. What geographic feature(s) determines the nature of the lahar distribution-you will note that these are not found everywhere...? I. J. How might you account for the variable width of the predicted lahars?
