Kasatochi Island ( Aleut : Qanan-tanax̂ ; Russian : Касаточий остров ), also known as Kasatochi volcano , is an active stratovolcano and part of the Andreanof Islands subgroup of the Aleutian Islands of southwestern Alaska . On 7 August 2008, Kasatochi began erupting explosively with an ash plume reaching 45,000 feet (14,000 m). The eruption lasted for 24 hours and destroyed most life on the island. It currently does not support any consistent human population.
67-729: Kasatochi Island is a member of the Aleutian Islands, which lie above a narrow ridge that separates the Bering Sea from the North Pacific . It lies at the Atka Pass northwest of the western tip of Atka Island and east of Great Sitkin Island . It is at 52.177° N latitude and 175.508° W longitude, with a summit elevation of 314 m (1030 ft.) It has a land area of 1.9503 sq mi (5.051 km). Kasatochi Island has

In 1924, at a conference organized by the American Society of Mammologists (ASM), the debate generated a public split between those in the Survey, promoting eradication, and those from the ASM who promoted some sort of accommodation.

In all areas surrounding the crater, the island is characterized by steep sea-cliffs, talus slopes, and small, boulder-filled beaches. These many habitat possibilities set the stage for the numerous species that took residence there. Before

The island is steeper to the northern side than the southern side, and slightly north of the center of the island is

This opportunity was due to the fact that rarely does such a devastating natural disaster occur in an environment where there had been extensive research on preexisting species and vegetation. By enhancing their understanding of the process on Kasatochi, they hoped to be able to apply gained knowledge to similar situations in the future. In
1273-590: The 2008 eruption, the Kasatochi Island landscape was steep and rugged, home to dense vegetation and different species of flora . Except crater walls and sea-cliffs, nearly the entire island was vegetated with grasses and herbaceous plants. This terrestrial vegetation created the habitat for many of the species unique to Kasatochi Island. The coastal and marine habitat flourished with their own species of vegetation as well, including many different types of sea grasses, kelp, corals, sponges, and roots (namely along
1340-702: The 2008 eruption. Before 2008, little was known about the eruptive history or probability of future eruptions on Kasatochi Island. There were no monitoring devices on the island, but devices on two nearby islands had indicated detectable seismic activity on Kasatochi for several years. Because of the lack of necessary technology, predicting the following eruption would have been an extremely unlikely feat. Thus, it happened quite rapidly and without much warning. On 7 August 2008, Kasatochi began erupting explosively with an ash plume maintaining an altitude of 35,000 feet and reaching 45,000 feet. The eruption lasted for 24 hours and included "two initial explosive pulses and pauses over

In 1939, the Bureau of Biological Survey moved from the Department of Agriculture to the Department of the Interior. On June 30, 1940, the Bureau of Fisheries and the Bureau of Biological Survey were combined to form the Department of the Interior's Fish and Wildlife Service . In 1956, the Fish and Wildlife Service

In 1896 it became the Division of Biological Survey . Clinton Hart Merriam headed the Division for 25 years and became

The Fish Commission operated a small fleet of research ships and fish-culture vessels. The Bureau of Fisheries inherited these in 1903, and then greatly expanded its fleet of seagoing vessels, including both patrol vessels for fishery enforcement in

In the 1956 reorganization that created the USFWS, the Bureau of Commercial Fisheries (BCF) assumed the responsibility within the USFWS for

Although the NMFS continued to operate the Pribilof tender until 1975, the rest of the ships were transferred from the NMFS to a unified NOAA fleet during 1972 and 1973. The modern NOAA fleet therefore traces its ancestry in part to

He concludes with the idea that "Large predatory mammals, destructive to livestock and to game, no longer have a place in our advancing civilization." The Survey subsequently placed over 2 million poisoned bait stations across

Later, up to 6 cm of ash was found on Adak and other neighboring islands,

Prior to the 2008 eruption, Kasatochi Island was a part of the Alaska Maritime National Wildlife Refuge (ANMWR).

This situation may have seemed similar to many other eruptions throughout history, including Surtsey in Iceland, Krakatau in Indonesia, Usu in Japan, Ksudach in Russia, and Mount St. Helens in the United States. However, the eruption of Kasatochi specifically gave scientists an extremely rare opportunity to study

At the time there were about 300 people living on the island, and while there were no immediate deaths or injuries, the long-term effects of this population being so close to the eruption are still unknown. The geological setting of Kasatochi was greatly impacted by the eruption. Where there had been beaches, forests, and soils once, there were now meters of deposits from

Ocean currents, productivity, and the habitable island geology created the ideal conditions for these select groups of fauna . The island differentiated itself from many of the others in the Aleutian chain by supporting a large diverse group of seabirds, most famously for their colony of more than 100,000 crested auklets and 150,000 least auklets , which

The USFWS partners with
3685-570: The summer of 2008, a team of researchers visited the island to observe and record the immediate consequences of the eruption on all present communities. The eruption had a massive effect on all aspects of the ecosystem, including soils, oceanic water, terrain, terrestrial plants, land, shore, and seabirds, arthropods, marine algae, and marine invertebrates. The goal was to recognize patterns of recolonization for each individual species and see how, if at all, they coincided with each other. There were many apparent patterns researchers noticed after studying
3752-426: The summer of 2009. Because of the intensity of this natural disturbance and the almost complete devastation of life on Kasatochi right after the eruption, the island became a textbook site for primary succession . Scientists took this opportunity and started a research project in 2009 to study ecosystem impact and long-term recovery. Their goal was to find the patterns and reasons for the returning of various species to

At present, it is found that most immigrants(whether by wind, flight, water, etc.) fail to find suitable habitats, so while they are continually being introduced, the majority will die. These dispersal methods will lead to greater species diversity only when the terrestrial habitat stabilizes in response to abiotic and external forces. These few examples of learned patterns by monitoring how

The abundance of fish and various marine life helped support the massive influx of auklets to the island every year. It was also noted for the presence of an endangered Steller sea lion rookery on the north half of the island. Near-shore benches were carved out of lava flows that could have been dated up to hundreds of years earlier. Approximately 1000 Steller sea lions occupied these rookeries before

With various agency reorganizations, the practice continued more or less apace through the early 1970s but though hundreds of thousands of coyotes were killed, their extreme adaptability and resilience led to little overall population reduction and, instead, their migration into an expanded habitat, including urban areas.

One specific example was the survival of arthropods, as most found during 2009 were either survivors of the disaster or their progeny.

These are the methods that are planned to bring back the largest amount of species; however,
