Volcanic eruption in Hawaii An eruption from the Pu‘u ‘Ō‘ō vent of Kilauea volcano, Hawaii. volcanic eruption, an eruption of molten rock, hot rock fragments, and hot gases through a volcano, which is a vent in a planet’s or satellite’s crust. Volcanic eruptions can cause disastrous loss of life and property. They range from relatively gentle eruptions, as typically seen in Hawaiian volcanoes, to massively destructive ones, such as the eruption of Vesuvius that destroyed Pompeii in 79 ce. Volcanic eruptions have captured the imagination of people over millennia, and they feature in several mythologies as well as works of fiction. These eruptions also play a role in climate change, with expelled gases such as carbon dioxide contributing to global warming, while ash, dust, and gases such as sulfur dioxide can drive global temperatures down.

The eruptions of Hawaii’s volcanoes fall into this category. In other cases, entrapped gases tear the magma into shreds and hurl viscous clots of lava into the air. In more violent eruptions, the magma conduit is hollowed out by an explosive blast, and solid fragments are ejected in a great cloud of ash-laden gas that rises tens of thousands of metres into the air. An example of this phenomenon is the 1980 eruption of Mount Saint Helens. Many explosive eruptions are accompanied by a pyroclastic flow, a fluidized mixture of hot gas and incandescent particles that sweeps down a volcano’s flanks, incinerating everything in its path. If the expelled ash or gases collect on a high snowfield or glacier, they may melt large quantities of ice, and the result can be a disastrous flood or landslide that rushes down a volcano’s slopes.

Volcanic ash can cause respiratory illnesses such as silicosis and can be particularly harmful to infants and people with chronic lung diseases. Gases such as hydrogen chloride, carbon monoxide, and hydrogen fluoride can cause both short- and long-term problems. Eruptions can cause economic harm that affects workers’ livelihoods and can force mass migrations of people in affected regions. The 2010 eruption of Iceland’s Eyjafjallajökull also demonstrated the threat posed to jet aircraft by high clouds of volcanic ash; this eruption led aviation authorities to ground flights across northern and central Europe for several days. Volcanoes can be classified by the manner in which they erupt. These six types of volcanic eruptions, starting with the least explosive, make up one classification system: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian. Each name corresponds to a region or to a specific volcano or historical eruption that exemplifies the type. Volcanic eruptions are not limited to Earth. Jupiter’s moon Io is subject to strong gravitational forces due to Jupiter’s mass as well as interaction with Jupiter’s other moons Europa and Callisto The 1815 eruption of Mount Tambora in Indonesia—the largest volcanic eruption in recorded history—had a tremendous impact on the world’s climate as well as its culture. Tambora expelled as much as 150 cubic km (roughly 36 cubic miles) of ash, pumice and other rock, and aerosols into the atmosphere. These materials blocked substantial amounts of sunlight from reaching Earth’s surface, eventually reducing the average global temperature by as much as 3 °C (5.4 °F). The following year was called the “year without a summer.” It was during this bleak period that Mary Shelley and her literary circle were confined indoors in Geneva, when she conceived of her masterpiece Frankenstein (1818).
