This volcano has come under intense scrutiny by the public and scientific communities due to its close proximity to several populated areas. There is some concern that if it experiences a major eruption, a tsunami may result. A tsunami would endanger many coastal towns located in Cook Inlet.
Their goal is to be able to provide an advanced, accurate and timely warning in the event of a major eruption, a tsunami or other hazardous tectonic condition.
This goal is beginning to be realized. Fossil found in this formation identify the rock as part of the Naknek formation consisting of thin bedded dark-grey siltstone and very fine sandstone.
Glacially striated exotic stone has been observed in several place on the south flank. These rocks indicate that the last Late Wisconsin glaciation between 30, and 23, years before the present yr B. Augustine is one of many volcanoes created as the Pacific plate is subducted under the North American plate.
As the plate is subducted, magma from the partially melted Pacific plate rises forming the volcanoes. The Aleutian trench marks the boundary between these two plates. This also marks the upper boundary of the Pacific "ring of fire"- an area of intense tectonic activity circling the Pacific Ocean.
Augustine first became active in the late Pleistocene. The earliest igneous rock that can be traced to its volcanic nature are eruptions of olivine basalt which interacted with water and dactic and rhyodactic pumiceous pyroclastic flows.
The volcano historically became active around the year yr B. Geological evidence of numerous debris avalanches have been documented. In recent historic time, a major eruption in caused the summit to collapse resulting in a debris avalanche which created a tsunami. The tsunami, measuring 6 m above sea level, flowed into English Bay Harbor located on the Kenia Peninsula Other eruptions occurred in, and These eruptions were less spectacular than the eruption, with smaller pyroclastic flow.

Geological Survey, March 31, March 31, Image Creator: Recent volcanic activity has been observed starting in January, The intensity of the activity has increased causing the AVO to issuer an orange alert - indicating that a major eruption is eminent.
Early geologists warned of the possibility of a repeat of the tsunami. Wahrhaftig, This concern was echoed in Waitt, However, a recent study by R.
Suleimani, predicts that an eruption would have to have a very large debris avalanche moving at a very high speed and must occur at high tide to have a significant effect on the town of Homer and Sledovia - 70 km to the southeast of Augustine.
In his opinion, a tsunami occurring in the Homer area is unlikely. Other coastal areas may not be that fortunate. The upper Cook Inlet is to shallow for a tsunami to threaten Anchorage.
NOAA, There is some threat of a pyroclastic flow into the sea, but Augustine is located far enough away from any populated for this to be a concern. Studies predict that the flow would disturb only the area within 6 km of the island.
The most prevalent hazard associated with the Augustine Volcano is the ash plume. Ash plumes are a great threat to air travel in the area. Ingestion of the ash by a jet engine results in a catastrophic failure of the engine.
Ash plumes can also shut down commercial fishing operations, shipping lanes, and oil production in the area of the plume. While the tsunami center usually does not monitor volcanic activity, in the case of Augustine, a tsunami event is most likely to result from the collapse of the flank resulting in a debris avalanche into Cook Inlet.Two examples are described below.
The first three interpretation methods are used on the same biblical passage. They are intended to illustrate how devout, thoughtful, sincere, and intelligent Christians can use different analysis techniques and arrive at totally different understandings of the same verses.
Augustine Volcano has been a prolific producer of large debris avalanches during the Holocene. Originating as landslides from the steep upper edifice, these avalanches typically slide into the surrounding ocean.
At least one debris avalanche that occurred in during an eruption initiated a far-traveled tsunami. The possible occurrence of .
