was Sumbawa, Indonesia, the year was 1815, and the
month was April. Everything was set for one of the
most explosive events in human history. Sumbawa
Island is home to the volcano called Tambora which
has an elevation of 9,348 ft. (2,850m) and a diameter
at sea-level of 38 mile. On April 5th of 1815 the
volcano, which had lain dormant for more than 5,000
years, began to erupt.
The mountain had been experiencing small eruptions
before it exploded in 1815 and the April eruption
left a deep summit caldera where the previous stratovolcano
stood, causing earthquakes as far away as Surabaya
(a distance of 500 km) in reaction to the collapse.
Ash exploded from the eruption and was carried as
far as east Java, approximately 900 km from Tambora.
Thunder-like sounds were heard up to 1,400 km away
and the entire eruption is estimated to have had
the volcanic explosion strength of seven. The eruption
column itself was roughly 44 km high vertically
and produced numerous pyroclastic flows. Tsunamis
were generated as a result of both the flows and
the shock waves from the collapsing caldera. In
total, the volcanic eruption lasted for two days
and ejected about 50 cubic km of magma. The eruption
was the largest that had occurred over past 1,000
years, with an immediate human impact of 92,000
As far-reaching as the immediate outputs of the
volcanic explosion were, the full effects of the
eruption had yet to be felt. The year after the
eruption, 1816, is often titled “the year without
summer," due to significantly cooler temperatures
throughout Europe and other reaches of the world,
resulting in such unusual phenomena as snow in June
in the northern hemisphere and cyclone tracks being
pushed to the south, bringing unusually wet weather
in many areas. Crop failures and famine abounded
the world over, marked by higher death rates that
exceeded anything on Earth in the past 10,000 years.
“The year without summer” is not a complete mystery,
however, for its causes are the typical results
of a large volcanic explosion, such as the Tambora
eruption. There are many who would disagree with
this hypothesis, claiming that the effects of a
volcanic eruption the size of Tambora could not
be as far-reaching or as destructive to cause “the
year without summer.”
