Long Before the Tonga Volcano There Was the 1964 Alaska Earthquake
Besides being home to 75 percent of the world's volcanos, the Pacific Ring of Fire is also responsible for 90 percent of the world's earthquakes, including the 1964 Alaska earthquake.

Earth just suffered an extremely powerful volcanic eruption with the eruption of the Hunga Tonga-Hunga Ha'apai volcano near the island nation of Tonga on January 15, 2022. This is thought to be the most powerful eruption since AD 1100.
The pressure wave generated by the explosion moved at more than 620 miles per hour and the resulting sonic boom was heard in Alaska, more than 5500 miles away.
That volcano sits within what's known as the Pacific "Ring of Rire", an area that contains 75 percent of the world’s volcanoes, and where 90 percent of the world’s earthquakes occur.
The Ring of Fire is over 25,000 miles (40,000 km) in length, running in a circular arc northward from New Zealand to Australia, then onward from Indonesia to the Philippines and Japan, then stretching eastward to the Aleutian Islands, and southward down the west coast of North America and along the west coast of South America.
