Mount Ruapehu of New Zealand

Mount Ruapehu is the highest mountain (2797 metres) in the North Island of New Zealand. This is one of the most active volcanic regions of its kind in the world, with the massive Taupo eruption occurring in AD 186, Tarawera erupting in 1886 and Ruapehu in 1945, 1995 and 1996.
Ruapehu made headlines around the world in 1995 when it began spitting rocks and steam.This $10 definitive stamp features a striking aerial photograph of the eruption in June 1996 and has issued by the  New Zealand Post on February 12, 1997 for commemorating the eruption event.
Volcanic activity reached a peak at the end of September 1995 with plumes of ash and steam reaching heights of 19 km. Ruapehu's volcanic activity intensified again in early 1996, with a flood of mud and boulders moving down the Whangaehu River in late April. During June, moderate-sized ash eruptions occurred, with lava bombs ejected 100-500 metres above the volcano's vent.
