Authorities of Kamchatka Territory and Petropavlovsk-Kamchatsky City must get ready for a big swell of eruption of the Koryak Volcano located at the 30 km distance from the city and its airport, which is the major air gateway of Kamchatka.
      
      Alexei Ozerov, the leading scientist of the Volcanology and Seismology Institute of Far Eastern Branch of the Russian Academy of Science has recently reported about this to RIA Novosti.
      
      “As compared to the eruption of 1956, the only one in the history of modern observations, the current eruption started in a more impetuous and powerful way” – the scientist pointed out. According to him, this is indicative of the possibility of a considerable intensification of the volcano activity.
      “Ash emissions and trails already now are quite dangerous for aviation, the hazard growing with the intensification of the eruption” – warned he.
      
      The Koryak Volcano has been in the state of explosive eruption (i.e. eruption with ash emissions) of average force since Thursday.
      In modern history only one eruption, starting in 1956 was observed. Back then a crack broke in the north-west slope of the volcano, with gases and ashes ejected. The eruption was weak and lasted till March 1957.
