The level of activity seen is similar to a superfast spreading mid-ocean ridge on Earth. [4] It is the largest volcano on Io, producing about 10% of Io’s total thermal emission. [ 5 ] Temperature measurements of thermal emission at Loki Patera taken by Voyager 1 's Infrared Interferometer Spectrometer and Radiometer (IRIS) instrument were ...
Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
The volcano erupts at temperatures of up to 1,650 degrees Celsius on to the surface of Io, which has an average temperature of negative 95 degrees Celsius. [7] Unlike volcanoes on Earth, Amirani can erupt for years at a time with constant lava flows pouring out onto Io's surface.
Animation of eruption from Tvashtar Paterae (Io), taken from imagery from the New Horizons probe in 2007 Lava flow at Tvashtar Paterae. Io, a moon of the planet Jupiter, is the most volcanically active body in the Solar System. [1]
In a volcanic eruption, lava, volcanic bombs, ash, and various gases are expelled from a volcanic vent and fissure. While many eruptions only pose dangers to the immediately surrounding area, Earth's largest eruptions can have a major regional or even global impact, with some affecting the climate and contributing to mass extinctions.
On June 15, 1991, a rumbling Mount Pinatubo grew and grew until it exploded in the biggest volcanic eruption on Earth in 100 years. Super-pressurized, gas-charged magma burst through and a cloud ...
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
A volcanic plume has been observed at Masubi by various spacecraft starting with Voyager 1 in 1979, though it has not been persistent like similar Ionian volcanoes Amirani and Prometheus. [2] Masubi is also notable for having one of the largest active lava flows on Io, with an additional 240 km (150 mi) flow forming between 1999 and 2007. [3]
