This cooling effect on the ocean surface usually lasts for several years as the lifetime of sulfate aerosols is about 2–3 years. [1] However, in the subsurface ocean the cooling signal may persist for a longer time and may have impacts on some decadal variabilities, such as the Atlantic meridional overturning circulation (AMOC).

Satellite view of a pumice raft from an undersea eruption in Tonga. Volcanic eruptions can have various impacts on maritime transportation. When a volcano erupts, large amounts of noxious gases, steam, rock, and ash are released into the atmosphere; fine ash can be transported thousands of miles from the volcano, while high concentrations of coarse particles fall out of the air near the ...
Shock images show roads split apart near Grindavik in Iceland as the country braced for a volcanic eruption following a series of earthquakes and evidence of magma spreading underground.. The ...
Submarine eruptions are volcano eruptions which take place beneath the surface of water. These occur at constructive margins, subduction zones and within tectonic plates due to hotspots. This eruption style is far more prevalent than subaerial activity. For example, it is believed that 70 to 80% of the Earth's magma output takes place at mid ...
Iceland residents describe ‘apocalyptic’ scenes as they flee volcano threat. Grindavik could be obliterated if volcanic eruption strikes. 04:30, Alisha Rahaman Sarkar. A volcanic eruption ...
People living in the Southern Hemisphere experienced purple sunsets for a few months after the eruption. A cooling effect of 0.1–0.5 °C (0.18–0.90 °F) was expected to last until spring (September–November) 2022. [55] The eruption was described as a once-in-a-thousand-year event for the Hunga caldera.

About 20–25% of all fatalities at volcanoes during the last 250 years have been caused by volcanic tsunamis. The most devastating volcanic tsunami in recorded history was that produced by the 1883 eruption of Krakatoa. The waves reached heights of 40 m (130 ft) and killed 36,000 people. [1]
