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.
Voyager 1 observation of Loki Patera and nearby lava flows and volcanic pits. Loki Patera on moon Io (artist's concept; 0:18). [1] Map of temperature and crust age of Loki Patera obtained by the Large Binocular Telescope. Loki Patera / ˈ l oʊ k i ˈ p æ t ə r ə / is the largest volcanic depression on Jupiter's moon Io, 202 kilometres (126 ...
Amirani is about the same age as Jupiter, which is around 4.5 billion years old.It is surrounded by the Gish Bar Patera. [4] Within the mountains of the crater, Amirani lies at the center of a frozen sulphuric lava field that consists of a half-circle shaped, 37 kilometer wide volcanic pit, which is connected to a 330 kilometer compound lava flow by a narrow channel.
Io, with two plumes erupting from its surface, Galileo image, June 1997. 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]
The names of volcanic features on Io use a combination of a name derived from mythological figures from around the world related to the Sun, fire, volcanoes, thunder, or smithing, places from the Greek mythological story of Io, Dante's Inferno, or from the name of a nearby feature on Io's surface and an approved descriptive term. The ...
These volcanic mountains are often smaller than the average mountain on Io, averaging only 1 to 2 km (0.6 to 1.2 mi) in height and 40 to 60 km (25 to 37 mi) wide. Other shield volcanoes with much shallower slopes are inferred from the morphology of several of Io's volcanoes, where thin flows radiate out from a central patera, such as at Ra Patera .
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 ...
The thrust faulting and uplifting of large crust blocks on Io are interpreted by a model proposed by Schenk and Bulmer's 1998 paper. [3] In the model, Io's crust keeps recycling. Violent volcanic activity brings lava to the surface and older, buried layers are forced to subside. The old volcanic crust materials are compressed laterally as they ...
