KOMPAS.com - How big is the Pacific Ring of Fire?
The Ring of Fire dominates the Pacific Ocean. It s a string of at least 450 active and dormant volcanoes that form a semi-circle, or horse shoe, around the Philippine Sea plate, the Pacific Plate, Juan de Fuca and Cocos plates, and the Nazca Plate.
There is a lot of seismic activity in the area.
About 90 percent of all earthquakes strike within the Ring of Fire.
This means people s lives are under almost constant threat in Indonesia, the Philippines, Malaysia, Japan, Australia and New Zealand, Papua New Guinea, and other island nations like the Solomon Islands, Fiji, and many more in Melanesia, Micronesia and Polynesia, all the way east to the western seaboard of the North and South Americas.

Tuesday, February 16th 2021, 2:34 pm - Aftershock sequences may persist for more than 2,000 years on the slowest-slipping faults, according to research.
After an earthquake strikes, its ripple effects can occur for years, perhaps decades or centuries, afterwards. The Feb. 13 earthquake in Japan is a perfect example of this.
The powerful 7.1-magnitude tremor that struck 89 km southeast of Sendai, Japan Saturday was an actual aftershock of the destructive and deadly 9.0-magnitude quake that rattled the same area nearly 10 years ago, according to the country s national meteorological agency.
Dozens of injuries were reported in the Fukushima and Miyagi prefectures after the Feb. 13 event, according to local media outlets, but there were no significant casualties.
As massive slabs of Earth squish into and grind past each other off the coast of the Pacific Northwest, many people may wonder when they will feel ensuing earthquakes. Although the U.S. Geological Survey cannot predict where and when future earthquakes will occur, the bureau, along with a team of organizations, helped create a system that can provide vital seconds of warning
A powerful earthquake of magnitude 7.0 on the Richter scale struck off the coast of northeastern Japan late on Saturday, jolting Fukushima, Miyagi, and Tokyo, among other areas.
