Where is the volcano that erupted 2022?
On 20 December 2021, an eruption began on Hunga Tonga–Hunga Ha’apai, a submarine volcano in the Tongan archipelago in the southern Pacific Ocean. The eruption reached a very large and powerful climax nearly four weeks later, on 15 January 2022.
How many volcanoes exploded in 2020?
There were 73 confirmed eruptions at some point during 2020 from 68 different volcanoes; 27 of those were new eruptions that started during the year. A stop date with “(continuing)” indicates that the eruption was considered to be ongoing as of the date indicated.
What volcano went off in 536?
It is suggested that an eruption of Krakatoa described as occurring in 416 by the Javanese Book of Kings actually took place in 535–536, there being no other evidence of such an eruption in 416.
Why was 536 AD the worst year to be alive?
In 2018, medieval scholar Michael McCormick nominated 536 as “the worst year to be alive” because of the extreme weather events probably caused by a volcanic eruption early in the year, causing average temperatures in Europe and China to decline and resulting in crop failures and famine for well over a year.
Why is year 536 considered the worst year in human history?
536 is the current consensus candidate for worst year in human history. A volcanic eruption, or possibly more than one, somewhere in the northern hemisphere would seem to have been the trigger.

What was the worst year on earth?
536 AD
1816. It was known as the ‘year without a summer’, as average global temperatures fell by around 1°C. Like 536 AD, the culprit for the drop in heat was due to volcanic ash that covered skies around the world.
What is a volcanic eruption?
Volcanoes occur when material significantly warmer than its surroundings is erupted onto the surface of a planet or moon from its interior. On Earth, the erupted material can be liquid rock (“lava” when it’s on the surface, “magma” when it’s underground), ash, cinders, and/or gas.
What happens when a volcano erupts?
An eruption can be explosive, sending material high into the sky. Or it can be calmer, with gentle flows of material. This photograph shows an eruption of Mount St. Helens in Washington in July 1980.
What are volcanoes?
The Short Answer: A volcano is an opening on the surface of a planet or moon that allows material warmer than its surroundings to escape from its interior.
How do scientists detect volcanic eruptions?
The MODIS Thermal Alert System, known as MODVOLC, now enables scientists to detect volcanic activity anywhere in the world within hours of its occurrence. MODVOLC uses data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensors, which fly aboard NASA’s Terra and Aqua satellites.
