浅間山 (Mount Asama) is a 火山 (volcano) between 群馬県 (Gunma Prefecture) and 長野県 (Nagano Prefecture).
It’s about 150 kilometers (93 miles) northwest of Tokyo.
Yesterday, the 気象庁 (Japan Meteorological Agency) issued a level 3 warning* that 浅間山 (Mount Asama) could erupt within 48 hours. About 45,000 residents near the volcano were told they may need to evacuate.
* (There are five volcano warnings. Level 1 is normal / safe. Level 2 is stay away from crater. Level 3 is non-residents should stay away from the volcano. Level 4 is nearby residents need to prepare to evacuate. Level 5 is evacuation / major eruption imminent.)
Japan has many 火山 (volcanoes)…the most famous is the symbol of Japan, 富士山 (Mt. Fuji)…but most are dormant.
浅間山 (Mount Asama) is one of Japan’s most active 火山 (volcanoes).
The 気象庁 (Japan Meteorological Agency) was correct.
浅間山 (Mount Asama) had a minor eruption this morning (Monday, February 2, 2009) just before 2:00AM (JST).
No one was injured and there was no reported property damage.
The last time 浅間山 (Mount Asama) erupted was on September 1, 2004. That eruption was also fairly minor…although ash from that eruption went 200 kilometers from the volcano.
It’s biggest eruption was about 220 years ago. There were 1500 casualties and alot of property damage in that eruption.
