Question

Can someone help me with a word problem please? :)

Answer 1

An earthquake measuring 6.4 on the Richter scale struck Japan in July 2007, causing exten- sive damage. Earlier that year, a minor earthquake measuring 3.1 on the Richter scale was felt in parts of Pennsylvania. How many times more intense was the Japanese earthquake than the Pennsylvania earthquake?

let me know if it helps or not, thanks

Answer 3

this looks like a similar problem, but would i have to know the formula for en earthquake? because that's what it was using

Answer 4

in the page i posted, you just use the formula

10^(m - n)

where m and n are the magnitudes of the earthquakes (m is the larger magnitude)
