[Left] Although volcanic eruption is one of the largest disturbances, the patterns of succession has not been generalized due to the varieties of eruption types and the responses of plant communities. Recently, Mount Usu erupted in 1977-1978 and in 2000. We are trying to clarify concretely the changes in plant communities by using permanent-plot survey. [Right] Photo taken on July 18, 2006. That means 29 years after the 1977-78 eruptions.

This mountain (398 m a.s.l.) is a volcanic lava dome close to Mount Usu, created during 1944 and 1945.
[Left] Mount Showa-Shinzan created by 1945 eruptions. Mimatsu diagram recorded the process of the development of this mountain. Mt. Showa-Shinzan is gropued into the volcanic clusuter of Usu volcanoes. The forest was dominated by Betula platyphylla var. japonica and Populus maximowiczii. Photo taken on Dec. 18 2004, by Uraguhi A.

The British ship "Providence" Lands in Abuta
On September 15, 1796 (Aug. 14, 1796 of Kansei Calendar), the Her Majesty's Ship Providence, lead by the British explorer Capt. William Robert Broughton, arrived and anchored off Abuta (Irie).
Receiving an urgent message, the Matsumae Clan dispatched one of their clansmen but he was unable to communicate with the crewmen verbally. On September 26 (Aug. 25 of Kanssei Calendar), another clansman, who had experienced with receiving Russians, was dispatched, and inspected the ship, gave them permission to copy the chart of the northern Japanese islands and asked them to leave.
In the meantime, the crewmen of the Providence went ashore at the mouth of the Horonai River by boat, drew drinking water, cut firewood from Mt. Horonai-nupuri (Mountain of SHIMIZU) and returned to the ship.
The whole story is handed down throught the yukar oral epic told by Taneranke Toshima.
On September 29 (Aug. 28 of Kanei Calendar), the Providence moved to Cape Etomo, surveyed the port of Mororan (Muroran), and on October 1 (Aug. 30 of Kansei Calendar), set sail for Cape Esan.
Captain Broughton is remembered as the person who named Funka Bay (Uchiura Bay).
