Ring of Fire Earthquakes

1. Are 90% of the worlds earthquakes really around the ring of fire?

2. Solve using date from QuakeFeed.

Here are examples of a 1,2, and 3

Score of 1

88% is what we got

Score of 2

We found that only 74% of earthquakes happen in the ring of fire. Here is a picture of QuakeFeed and our math.

Score of 3

We found that 65% of earthquakes have happened in the ring of fire region in the last 30 days. We filtered out some earthquakes and only included earthquakes greater than 2.5 on the Richter scale. We think this proves the video wrong as 65% is not really that close to 90%. Here is a picture of QuakeFeed and our math.

Score of 4 (something very special of course!)
