Although the Mount Tambora eruption reached a violent climax on 10 April 1815, [5] increased steaming and small phreatic eruptions occurred during the next six months to three years. The ash from the eruption column dispersed around the world and lowered global temperatures in an event sometimes known as the Year Without a Summer in 1816. [6]
The main cause of the Year Without a Summer is generally held to be a volcanic winter created by the April 1815 eruption of Mount Tambora on Sumbawa. [7] [8] [9] The eruption had a volcanic explosivity index (VEI) ranking of 7, and ejected at least 37 km 3 (8.9 cu mi) of dense-rock equivalent material into the atmosphere. [10]
A moderate-sized eruption on 5 April 1815 was followed by thunderous detonation sounds that could be heard in Ternate on the Molucca Islands, 1,400 kilometres (870 mi) from Mount Tambora. On the morning of 6 April 1815, volcanic ash began to fall in East Java , with faint detonation sounds lasting until 10 April. [ 31 ]

Three great columns of flame rose in the sky over Mount Tambora on April 10, 1815. The long-dormant Indonesian volcano had rumbled to life five days earlier with a thunderous detonation followed.
This process raised Mount Tambora as high as 4,300 m (14,000 ft), making it one of the tallest peaks in the Indonesian archipelago, and drained off a large magma chamber inside the mountain. In 1815, Tambora erupted with a rating of seven on the volcanic explosivity index; the largest eruption since the Lake Taupō eruption in AD 181.
Two of the four eruptions were previously identified: Mount Tambora in Indonesia exploded in 1815, and Cosegüina erupted in Nicaragua in 1835. The volcano that produced the 1808/1809 eruption ...
The other notable blast, researchers say, is believed to have been one of the strongest eruptions of the last 10,000 years, likely only comparable to the 1815 eruption of Mount Tambora. That Mount ...
