This property of both nitro and nitrate groups is because their thermal decomposition yields molecular nitrogen N 2 gas plus considerable energy, due to the high strength of the bond in molecular nitrogen.
Mount Ararat (16,940 feet, 5165 m) is the largest volcano in Turkey. Although not currently active, its most recent eruption has probably been within the last 10,000 years.
Olympus Mons, the largest volcano on Mars, is so big that it can be seen with many common backyard telescopes. The largest active volcano on Earth is Mauna Loa in Hawaii, which has erupted off and on for the past 700,000 years. But it is about 2,000 square miles in size, a tiny fraction of Tamu Massif.
