When and where were the worst earthquakes in the Ring of Fire?

The worst earthquake in the Ring of Fire - and, with it, the world - struck Chile on May 22, 1960. It was a 9.5-magnitude quake. That's according to the US Geological Survey's list of the "Largest Earthquakes in the World Since 1900."

It's closely followed by the Great Alaska Earthquake of 1964 (magnitude 9.2), the Northern Sumatra earthquake - also known as the Indian Ocean Tsunami - on December 26, 2004 (magnitude 9.1), and one off the East Coast of Honshu, Japan, on March 11, 2011 (magnitude 9.0), which led to a tsunami and ultimately the nuclear disaster at Fukushima.

Most of the earthquakes on the list are strictly within the Ring of Fire, and they range from magnitude 9.5 to 8.5.

Given all this activity, can't we predict earthquakes in the Ring of Fire?

No. Most experts will tell you it's (so far) been impossible to predict earthquakes. Even if two happen within the ring in close succession, it is hard to say the one had anything to do with the other. One earthquake will not necessarily cause another.

Some seismologists are cautiously open to the idea that whatever we do as humans - whether it's testing nuclear explosives or deep-sea drilling - all has a potential impact. But there's little or no hard, scientific proof.

As for the Ring of Fire specifically, the region is under constant tension. When a quake strikes, that tension is temporarily relieved, but it soon starts to build again.

So all that is left for the people who live around the Ring of Fire is to be aware of the danger, perhaps to live further inland, build safer, earthquake resistant housing, and for nations everywhere to improve oceanic and land-based early-warning systems to help minimise the risk to life.
