The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Heard Island is the top of an active stratovolcano on the Kerguelen Plateau in the southern Indian Ocean, about 4000 km southwest of Western Australia. Part of Australian territory, along with McDonald Island to the west, Heard is one of Australia's two currently active volcanoes.
The volcano is frequently active, and occasional reports of eruptions date back to 1881. Since about 1980, remote sensing mostly via satellites has been able to detect more and frequent activity at the volcano.
The 368 sq km island with its highest point Mawson Peak at 2745 m forms the highest point of Australian territory outside Antarctica.
The uninhabited island was discovered by and named after Captain John Heard in 1853. Its remote location and typically extremely adverse weather and wind conditions make it difficult to access and only few expeditions have reached it. An Australian navy base existed on the island at Atlas Cove on the western side of Big Ben between December 1947 and March 1955.
Weak effusive activity continues from the volcano and seems to have picked up during the past days. Recent satellite imagery revealed an elongated source of heat emission on the upper NW flank, which likely corresponds to a new small lava flow approx. 500 m long that occurred as result of overflow from the crater. ...more
In addition, dark elongated deposits on the volcano's icy slopes could be detected that are likely the results of mud or melt-water flows that occurred as a result of new lava effusion from the summit. [less]

A new strombolian-type, explosive-effusive eruption has been detected at the summit of the remote but frequently active volcano in the southern Indian Ocean. ...more
In late January 2017, weak strombolian-type explosions from the summit crater began to show up as thermal signal and caused light ash falls that darkened the snow-covered slopes, something that could be detected some satellite images. Since early February, activity has increased and also become effusive: a new lava flow was erupted onto the the upper northwestern slope of Mawson Peak, seen on the attached satellite image from 4 Feb.

Ijen volcano photos: Ijen volcano in East Java is famous for its turquoise acid crater lake and the large sulfur deposits that are being mined by local workers. At night, the scene is illuminated by ghostly blue flames, as sulfur ignites.
