"The strongest recorded earthquake in the world took place in Child on May 22, 1960. It had a magnitude of 9.5 on the Richter scale. The strongest quake actually recorded in Canada was magnitude 8.1 on August 22, 1949 and occurred off the Queen Charlotte Islands.
a)How many times more powerful was the Chilean quake than the Queen Charlotte quake?
b) If an earthquake only half as strong as the Queen Charlotte one were to happen today, what would its magnitude be?"
Anyone that can do this for me is awesome.
