Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Yasur
A plume rises above the summit crater of Yasur, seen here from the west across Lake Siwi in 1988. Yasur has produced near-continuous Strombolian activity since at least 1774 and this style of activity may have continued for the past 800 years. The mostly-unvegetated cone is has a 400-m-wide summit crater. Photo by Ian Nairn, 1988 (New Zeland Geological Survey).

Data from the MaGa Database
Location: Yasur
(View Details at MaGa DB)
Description: Yasur, the best-known and most frequently visited of the Vanuatu volcanoes, has been in more-or-less continuous strombolian and vulcanian activity since Captain Cook observed ash eruptions in 1774. This style of activity may have continued for the past 800 years. Located at the SE tip of Tanna Island, this mostly unvegetated pyroclastic cone has a nearly circular, 400-m-wide summit crater. Yasur is largely contained within the small Yenkahe caldera and is the youngest of a group of Holocene volcanic centers constructed over the down-dropped NE flank of the Pleistocene Tukosmeru volcano. The Yenkahe horst is located within the Siwi ring fracture, a 4-km-wide, horseshoe-shaped caldera associated with eruption of the andesitic Siwi pyroclastic sequence. Active tectonism along the Yenkahe horst accompanying eruptions has raised Port Resolution harbor more than 20 m during the past century.(GVP)
