What types of volcanic hazards would be associated with Mount Redoubt?
As hot gases and lava erupt from the volcano, the snow will melt, possibly sending floods of water and debris down the mountain. These volcanic floods are called lahars, and a lahar from Redoubt would likely travel down the Drift River, which drains the volcano on the north.
What type of lava does Mt Redoubt have?
Redoubt: Geology and Hazards The early stages of its growth were characterized by dacitic explosive eruptions, including pyroclastic flows and lava domes. Later cone-building eruptions, beginning about 340,000 years ago, became less silicic, producing basalt and basaltic andesite lava flows, scoria and ash flows.
What caused Mount Redoubt to erupt?
The 1989-90 eruption of Redoubt Volcano, 177 km southwest of Anchorage, Alaska, began on December 14, 1989, less than 24 hours after a swarm of earthquakes struck beneath the volcano. A huge cloud of ash heralded the volcano’s fourth and most damaging eruption of this century.
