Tambora’s catastrophic eruption began on April 5, 1815,. A shattering blast blew the mountains apart on the evening of April 10. The blast killed at least 10,000 islanders and destroyed the homes of 35,000 more. Before its eruption Mount Tambora was about 4,300 meters (14,000 feet) high. After the eruption ended, a caldera spanning some 6 km (3.7 miles) across remained.
Many volcanologists regard the Mount Tambora eruption as the largest and most-destructive volcanic event in recorded history, expelling as much as 150 cubic km …show more content…
Modern-day experts estimate smaller eruptions occurred for as many as three years before the 1815 explosion. Following its initial upsurge, which produced ash and thunder-like sounds that could be heard up to 850 miles away, a larger explosion took place on April 10 and 11, 1815. This eruption produced three columns of fire that historical records describe as "rising to a great height." The volcano's eruption was so powerful; it left a massive indentation, known as a caldera, in the center of the mountain, a remnant that remains in July 2011.
Effects
Mount Tambora's historic eruption in 1815 had global effects. Not only were the earthquakes ignited by the explosion felt up to 300 miles away, but the ash and magma, or volcanic rock, produced covered more than 30 cubic miles. The ash ejected by Mount Tambora's eruption reduced the amount of sunlight that reached Earth's surface and is credited with causing the global cooling effect that led to the "year without a summer" in
