Volcano Calendar 2020: We're proud to present our 2020 volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past two years.
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.

A new eruption is in progress at the volcano. Since end of October, strong thermal signals indicate the presence of lava. ...more
Satellite images show a lava flow traveling from the summit crater on the upper SW slope. Due to frequent cloud cover on the remote island, it is not known when exactly the activity started or whether it is still in progress (although likely).

Introduction to Plate Tectonics: The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
