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]
The eruption caused a volcanic winter. During the Northern Hemisphere summer of 1816, global temperatures cooled by 0.53 °C (0.95 °F). This cooling directly or indirectly caused 90,000 deaths. The eruption of Mount Tambora was the largest cause of this climate anomaly. [22]
3. 1816 – The Year Without a Summer. In April of 1815, Mount Tambora in Indonesia exploded in a powerful eruption that wreaked havoc, disrupted the weather patterns worldwide, and killed tens of ...
Before the site of the eruption was known, an examination of ice cores around the world had detected a large spike in sulfate deposition from around 1257 providing strong evidence of a large volcanic eruption occurring at that time. In 2013, scientists linked the historical records about Mount Samalas to these spikes.
The lingering effect of the volcanic winter of 536 was augmented in 539–540, when another volcanic eruption caused summer temperatures to decline as much as 2.7 °C (4.9 °F) below normal in Europe. [2] There is evidence of still another volcanic eruption in 547 which would have extended the cool period.
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...
