The volcano
Avachinsky (2,749m - 8,993ft), also known as Avacha or Avacha Volcano or Avachinskaya Sopka, in Russian Авачинская сопка, Авача) is an active stratovolcano on the Kamchatka Peninsula in the far east of Russia. It lies within sight of the capital of Kamchatka Krai, Petropavlovsk-Kamchatsky. Together with neighboring Koryaksky volcano, it has been designated a Decade Volcano, worthy of particular study in light of its history of explosive eruptions and proximity to populated areas.
Avachinsky lies on the Pacific Ring of Fire, at a point where the Pacific Plate is sliding underneath the Eurasian Plate at a rate of about 80 mm/year. A wedge of mantle material lying between the subducting Pacific Plate and the overlying Eurasian Plate is the source of dynamic volcanism over the whole Kamchatka Peninsula.
The volcano is one of the most active volcanoes on the Kamchatka Peninsula, and began erupting in the middle to late Pleistocene era. It has a horseshoe-shaped caldera, which formed 30-40,000 years ago in a major landslide which covered an area of 500 km² south of the volcano, underlying the city of Petropavlovsk-Kamchatsky. Reconstruction of a new cone inside the caldera occurred in two major eruption phases, 18,000 and 7,000 years ago.
Avachinsky has erupted at least 16 times in recorded history. Eruptions have generally been explosive, and pyroclastic flows and lahars have tended to be directed to the south west by the breached caldera. The most recent large eruption (VEI=4) occurred in 1945, when about 0.25 km³ of magma was ejected.
In 1991 and 2001, the volcano has had small eruptions.
Avachinsky's last eruption occurred in 2008. This eruption was tiny compared to the volcano's major Volcanic Explosivity Index 4 eruption in 1945.
The painter
John Webber RA (1751– 1793) was an English artist best known for his images of Australasia, Hawaii, Alaska and Kamchatka Peninsula.
Webber was born in London, educated in Bern and studied painting at Paris. His father was Abraham Wäber, a Swiss sculptor who had moved to London, and changed his name to Webber.
Webber served as official artist on James Cook's third voyage of discovery around the Pacific (1776–80) aboard HMS Resolution. At Adventure Bay in January 1777 he did drawings of "A Man of Van Diemen's Land" and "A Woman of Van Diemen's Land". He also did many drawings of scenes in New Zealand and the South Sea islands. On this voyage, during which Cook lost his life in a fight in Hawaii, Webber became the first European artist to make contact with Hawaii, then called the Sandwich Islands. He made numerous watercolor landscapes of the islands of Kauai and Hawaii, and also portrayed many of the Hawaiian people.
In April 1778, Captain Cook's ships Resolution and Discovery anchored at Ship Cove, now known as Nootka Sound, Vancouver Island, Canada to refit. The crew took observations and recorded encounters with the local people. Webber made watercolour landscapes including "Resolution and Discovery in Ship Cove, 1778". His drawings and paintings were engraved for British Admiralty's account of the expedition, which was published in 1784.
Back in England in 1780 Webber exhibited around 50 works at Royal Academy exhibitions between 1784 and 1792, and was elected an associate of the Royal Academy in 1785 and R.A. in 1791. Most of his work were landscapes. Sometimes figures were included as in "A Party from H.M.S. Resolution shooting sea horses", which was shown at the academy in 1784, and his "The Death of Captain Cook" became well known through an engraving of it. Another version of this picture is in the William Dixson gallery at Sydney.
