What damage did the Augustine Volcano cause?
In mid-March renewed extrusion resulted in the building of a new, higher summit lava dome and two blocky lava flows on the north and northeast flanks of the cone. The eruption resulted in ash fall on many south-central Alaskan communities and disrupted air traffic in the region.
What happened when the Augustine Volcano erupted?
The irregular coastline of Augustine Island is due to the repeated catastrophic collapse of the summit dome, forming debris avalanches down the flanks and into Cook Inlet….

What areas are most affected by volcanic eruptions?
After Indonesia, the most at-risk countries include the Philippines, Japan, Mexico, Ethiopia, Guatemala, Ecuador, Italy, El Salvador and Kenya. Lava and ash deserve the awe they inspire, notes Orskin: they can be incredibly destructive. About 278,000 people have perished due to volcanoes since 1600.
What is the extreme risk zone during volcanic eruption?
This is the death zone. This location is subject to intra crater earthquakes, extreme temperatures, choking and toxic gases, falling projectiles, and unstable terrain. An eruption may give 30 seconds warning at most. This region is incompatible with life.
What plate boundary is Augustine Volcano?
Mount Augustine is located in a chain of volcanic islands running parallel to the Aleutian Trench, which is itself located where the Pacific Plate is being subducted under the North American Plate, at an area called the Aleutian Megathrust….

What year did Augustine last erupt?
2006
Augustine Volcano, in the Cook Inlet of the Gulf of Alaska, erupted on January 13 and 14, 2006.
Which volcano is most likely to erupt next?
We know that Mount St. Helens is the volcano in the Cascades most likely to erupt again in our lifetimes.
What is a safe distance to live from a volcano?
The safe distance from an active volcano is generally 5kms or more but you should check for the latest NEMA information. Beyond this distance the major hazards will be ashfall and volcanic gas. Breathing in small amounts of ash particles infrequently may only cause discomfort rather than pose a health hazard.
How close is too close to a volcano?
Typically you are more than a 1 km away from volcanic vents (with effusive or small to moderate explosive activity), but more than 5-10 km away from volcanoes producing moderate to strong explosive activity and you are outside valleys where pyroclastic flows could be channeled.
How did Augustine Volcano form?
Augustine is possibly the youngest volcano in the Cook Inlet. The volcano began forming 25,000 to 40,000 years ago. At least 13 debris avalanches have occurred in the past 2500 years, which were the result of lava dome collapse.
What were the effects of the St Augustine Volcano eruption?
The eruption resulted in ash fall on many south-central Alaskan communities and disrupted air traffic in the region. Augustine’s frequent eruptions and relatively easy access have long drawn volcanologists to study the accumulation, ascent, and eruption of andesitic to dacitic magma.
How many times has Augustine Volcano erupted?
Augustine Volcano. The volcano is frequently active, with major eruptions recorded in 1883, 1935, 1963–64, 1976, 1986, and 2006. Minor eruptive events were reported in 1812, 1885, 1908, 1944, and 1971. The large eruptions are characterized by an explosive onset followed by the quieter effusion of lava.
What type of volcano is August Augustine?
Augustine Volcano ( Sugpiaq: Utakineq; Dena’ina : Chu Nula) is a stratovolcano in Alaska consisting of a central complex of summit lava domes and flows surrounded by an apron of pyroclastic, lahar, avalanche, and ash deposits. The volcano is frequently active, with major eruptions recorded in 1883, 1935, 1963–64, 1976, 1986, and 2006.
Are there great landslides and debris avalanches on St Augustine?
Since 1980 many hummocky coarsely fragmental deposits on Augustine’s lower flanks have come to be interpreted as deposits of numerous great landslides and debris avalanches. Thermal image after the January 2006 eruptions. White parts of the image are warmer than dark areas.
