A type of seismic zone is a Wadati–Benioff zone which corresponds with the down-going slab in a subduction zone. [2] The world's greatest seismic belt, known as the Circum-Pacific seismic belt, [3] is where a majority of the Earth's quakes occur. Approximately 81% of major earthquakes occur along this belt.
It is the second most seismically active region in the world, after the circum-Pacific belt (the Ring of Fire), with 17% of the world's largest earthquakes. [ 2 ] The belt is the result of Mesozoic -to- Cenozoic -to-recent closure of the Tethys Ocean and process of collision between the northward-moving African , Arabian , and Indian plates ...
The world is divided into 754 Flinn–Engdahl regions (F-E regions), which are based on political and geographical boundaries as well as seismic activity. More active zones are divided into smaller F-E regions whereas less active zones belong to larger F-E regions.
Over the past century, scientists have only observed five magnitude-9.0 or higher earthquakes — all megathrust temblors like the one predicted for the Cascadia Subduction Zone.
[note 4] The next most seismically active region (5–6% of earthquakes and some of the world's largest earthquakes) is the Alpide belt, which extends from central Indonesia to the northern Atlantic Ocean via the Himalayas and southern Europe. [6] [7] From 1900 to the end of 2020, most earthquakes of magnitude M w ≥ 8.0 occurred in the Ring ...

Megathrust earthquakes are the most powerful earthquakes known to occur, and can exceed magnitude 9.0, which releases 1,000 times more energy than magnitude 7.0 and 1 million times more energy than a magnitude 5.0. [18] [19] [20] They occur when enough energy (stress) has accumulated in the "locked" zone of the fault to cause a rupture. The ...
