wow wow wow ! Augustine (Alaska) wakes up - steam! Watch on it few weeks as constant tremor was visible and series of eqs (see at previous pages here it was marked) - and now confirmed cam [ link to www.avo.alaska.edu] Quoting: Anonymous Coward 36508752 another cam [ link to www.avo.alaska.edu] Quoting: Anonymous Coward 36508752 [ link to www.volcano.si.edu] Volcano Type: Lava domes Volcano Status: Historical Last Known Eruption: 2006 Augustine volcano, rising above Kamishak Bay in the southern Cook Inlet about 290 km SW of Anchorage, is the most active volcano of the eastern Aleutian arc. It consists of a complex of overlapping summit lava domes surrounded by an apron of volcaniclastic debris that descends to the sea on all sides. Few lava flows are exposed; the flanks consist mainly of debris-avalanche and pyroclastic-flow deposits formed by repeated collapse and regrowth of the volcano's summit. The latest episode of edifice collapse occurred during Augustine's largest historical eruption in 1883; subsequent dome growth has restored the volcano to a height comparable to that prior to 1883. The oldest dated volcanic rocks on Augustine are more than 40,000 years old. At least 11 large debris avalanches have reached the sea during the past 1800-2000 years, and five major pumiceous tephras have been erupted during this interval. Historical eruptions have typically consisted of explosive activity with emplacement of pumiceous pyroclastic-flow deposits followed by lava dome extrusion with associated block-and-ash flows.
