I want to know the answer to the following question:
The Pacific Ring of Fire contains what percentage of the earthquakes on Earth?
All the background I'm provided with is that "The West Coast of the continental United States and areas of Alaska (including the Aleutian Islands, the Alaskan Peninsula and southern Alaskan coast) make up part of the Pacific Ring of Fire, an area of heavy tectonic and volcanic activity that is the source of 90% of the world's earthquakes.[citation needed]". Is that enough to answer the question?
Answer: yes
