Modified Mercalli intensity IMM of IX was assigned to an area of about 80 km long and 30 km wide during an earthquake which occurred in the Western United States. Compute the peak ground acceleration (PGA) from this earthquake. Compute the value of PGA by using both equations given below and comment on the results. Estimate the intensity Ijma according the earthquake in the Japanese Meteorological Agency scale. PGA = 0.91·10031-IMM PGA = 1.02 · 10º.30-IMM

Modified Mercalli intensity IMM of IX was assigned to an area of about 80 km
long and 30 km wide during an earthquake which occurred in the Western
United States. Compute the peak ground acceleration (PGA) from this
earthquake. Compute the value of PGA by using both equations given below
and comment on the results. Estimate the intensity Ijma according the
earthquake in the Japanese Meteorological Agency scale.
PGA = 0.91·10031-IMM
PGA = 1.02 · 100.30-IMM
