Urup ((ロシア語:Уру́п), , ) is an uninhabited volcanic island in the Kuril Islands chain in the south of the Sea of Okhotsk, northwest Pacific Ocean. Its name is derived from the Ainu language word for salmon trout. ==Geography and climate== Urup has a roughly rectangular shape, measuring along its long axis and approximately along its narrow axis. It is the fourth largest of the Kuril Islands, with an area of 1430 km² The highest point is Gora Ivao (). The strait between Urup and Iturup is known as the Vries Strait, after Dutch explorer Maarten Gerritsz Vries, the first recorded European to explore the area. The strait between Urup and Simushir is known as the Boussole Strait, after the French word for "compass", which was the name of one of La Pérouse's vessels. This French mariner explored the area of the Kuril Islands in 1787. Urup consists of four major groups of active or dormant stratovolcanos: * Kolokol Group (), with a height of has erupted as recently as 1973. * Rudakov (), with a height of has a 700 meter wide, funnel-like crater containing a 300 meter wide lake * Tri Sestry ((ロシア語:Три сестры);), with a height of has flanks cut by deep ravines and has numerous hot springs. * Gora Ivao (), with a height of is the highest point on the island. The southeast-most cone bisects a glacial valley, forming a lake. Despite its temperate latitude, the cold Oyashio Current and powerful Aleutian Low combine to give Urup a subarctic climate (Köppen ''Dfc'') with mild, foggy summers and cold, snowy winters. In reality the climate resembles the subpolar oceanic climate of the Aleutian Islands much more than the hypercontinental climate of Siberia proper or Manchuria, but the February mean of is well below the limit of “oceanic” climates. Urup, like all the Kuril islands, experiences extremely strong seasonal lag, with the highest temperatures in August and September, the lowest in February and temperatures typically in fact warmer at the autumn equinox than at the summer solstice. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Urup」の詳細全文を読む スポンサード リンク
