Volcanic aerosols from huge volcanoes (VEI>=5) directly reduce global mean sea surface temperature (SST) by approximately 0.2-0.3 °C, [1] [3] milder than global total surface temperature drop, which is ~0.3 to 0.5 °C, [4] [5] [6] according to both global temperature records and model simulations. It usually takes several years to be back to ...
A volcanic eruption is essentially the only natural way for short-lived – less than a few years – gases like sulfur dioxide and water vapor to make it into the stratosphere.

Video of lava agitating and bubbling in the volcano eruption of Litli-Hrútur, 2023. Volcanoes can cause widespread destruction and consequent disaster in several ways. One hazard is the volcanic eruption itself, with the force of the explosion and falling rocks able to cause harm. Lava may also be released during the eruption of a volcano; as ...
The volcanic island of Anak Krakatau in Indonesia saw an eruption on 22 December 2018 which caused a deadly tsunami, with waves surging up to five meters in height. The tsunami killed at least 437 ...
A volcanic hazard is the probability a volcanic eruption or related geophysical event will occur in a given geographic area and within a specified window of time. The risk that can be associated with a volcanic hazard depends on the proximity and vulnerability of an asset or a population of people near to where a volcanic event might occur.
