Detailed explanation-1: -The Volcanic Eruption of Mt. Tambora. A 13, 000-foot-high volcano on the island of Sumbawa, near Bali, Indonesia, was the primary cause of the Year Without a Summer. The eruption happened in April of 1815 and was one of the greatest volcanic eruptions in history.

Detailed explanation-2: -The blast, nearly 100 times as large as that of Mount St. Helens in 1980, sent a massive cloud of miniscule particles into the atmosphere. As the particle cloud blew its way around the globe it reflected sunlight, causing a meteorological phenomenon to which we now refer as the “year without a summer.”

Detailed explanation-3: -On April 5, 1815, Mount Tambora, a volcano, started to rumble with activity. Over the following four months the volcano exploded-the largest volcanic explosion in recorded history.

Detailed explanation-4: -In April of 1815, Mount Tambora exploded in a powerful eruption that killed tens of thousands of people on the Indonesian island of Sumbawa. The following year became known as the “year without a summer” when unusually cold, wet conditions swept across Europe and North America.

Detailed explanation-5: -Tambora was the source of history’s largest explosive eruption, in April 1815. Pyroclastic flows reached the sea on all sides of the peninsula, and heavy tephra fall devastated croplands, causing an estimated 60, 000 fatalities.
