Kizimen ((ロシア語:Кизимен)) is a stratovolcano located in the southern part of Kamchatka Peninsula, Russia. The volcano was in a dormant state since an eruption in 1929, but on 2 September 2009 it was reported by Georgina Cooper for the Reuters news agency that the crater lake temperature had risen 10 degrees Celsius in a week and plumes of steam were rising from its flanks.〔("Volcano stirs, may blow soon" ), ''Reuters'', Retrieved on 2009-05-09.〕 The activity continued throughout 2010, with the formation of new fumaroles reported in November.〔("Kizimen Volcano" ), ''VolcanoLive.com'', Retrieved on 2011-08-02.〕 Seismic activity and ash emission continued to build over the following weeks, and in January 2011 a hotspot was recorded, indicating the presence of lava. In early February 2011 the volcano sent a column of ash several kilometres high. Air traffic was alerted and told to avoid the area.〔("Russian volcano erupts sending ash four kilometres high" ), ''BBC'', Retrieved on 2011-07-02.〕 In April 2011, it was reported that the volcanic activity and ash were threatening the endangered wild reindeer of the area.〔(【引用サイトリンク】url=http://english.ruvr.ru/2011/04/20/49201730.html )〕 On 31 December 2012, following a 24 hour period of some 357 earthquakes reported under the volcano, Kizimen was raised to 'orange alert' status. An eruption was reported on 10 January 2013, with the ash plume reaching altitude.〔("Kizimen Volcano" ),''VolcanoLive.com'', Retrieved 2013-05-04〕 On December 7, 2013 activity at Kizimen and nearby Kliuchevskoi significantly increased, continued during November 29 - December 7, prompting KVERT to raise the Alert Level to Red. Ash plumes rose to altitudes of 5.5–6 km (18,000-19,700 ft) a.s.l. and drifted more than 212 km NE and over 1,000 km E. According to a news article, a warning to aircraft was issued for the area around the volcanoes. Video showed gas-and-steam activity, and satellite images detected a daily weak thermal anomaly. On December 9, the Alert Level was lowered to Green when the eruptions stopped. The volcano is not well understood, and research〔("Kizimen Volcano, Kamchatka - A future Mount St. Helens?" ), ''KSCNET.ru'', Retrieved on 2011-08-02.〕 has indicated that the volcano could erupt in a similar fashion to the catastrophic 1980 eruption of Mount St Helens. ==See also== * List of volcanoes in Russia * List of ultras of Northeast Asia 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「Kizimen」の詳細全文を読む スポンサード リンク
