The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes . It is about 40,000 km (25,000 mi) long [1] and up to about 500 km (310 mi) wide, [2] and surrounds most of the Pacific Ocean . The Ring of Fire contains between 750 ...
List of countries by natural disaster risk. Maps of the 2022 WorldRiskIndex and its components. The report systematically considers a country's vulnerability and its exposure to natural hazards to determine a ranking of countries around the world based on their natural disaster risk. The WorldRiskIndex (WRI), developed by the Institute for ...
The 1989 Loma Prieta earthquake occurred on California's Central Coast on October 17 at 5:04 p.m. local time. The shock was centered in The Forest of Nisene Marks State Park in Santa Cruz County, approximately 10 mi (16 km) northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains.

An earthquake is the shaking of the surface of Earth resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes may also be referred to as quakes, tremors, or temblors. The word tremor is also used for non-earthquake seismic rumbling . In its most general sense, an earthquake is any seismic event ...
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
