“The Year Without
A Summer” – 1816
By James Donahue
Throughout much of the
Northern Hemisphere there were abnormal weather patterns in 1816 that caused crops to fail and an estimated 200,000 people
starved to death. Thus 1816 went down in history as “The Year Without A Summer.”
It is recorded that the
climate aberrations were especially felt in the American Northeast, the Canadian Maritimes and in Northern Europe. In May that year,
frost killed off most of the planted crops, then in June, two large snowstorms, one of them dumping 10 inches of snow in Maine, swung the final blow on that season’s farm crops.
The cold dismal weather
continued throughout the summer, however. In July and August, ice was observed on lakes and rivers as far south as Pennsylvania. They said rapid and dramatic temperature swings were
common, with thermometers rising to above-normal levels of 95 degrees, Fahrenheit, and then dipping to near freezing within
The cause of this odd
weather is believed to have been the eruption of a single volcano in the Indonesian
Islands the year before.
Mount Tambora, a stratovolcano in the island of Sumbawa, literally exploded on April
10, 1815, becoming the most violent volcanic eruption in several hundred years. It was more powerful than even Krakatoa, which
gained much more attention after it blew out an entire island and killed thousands of people for hundreds of miles around
Because it occurred in
such a remote part of the then-known world, the Tambora eruption was hardly noticed by people in Europe and North
America. But it took its toll in the area where it happened.
The eruption lasted for
only five days, but it released roughly four times the energy of the Krakatoa blast and ejected an estimated 100 cubic kilometers
of volcanic ash high into the stratosphere. The explosion left a caldera measuring four miles wide and reduced a 13,000-foot
high mountain to only 9,000 feet.
Tambora, a city of an
estimated 10,000 people, was buried under the tons of volcanic ash. The eruption caused an estimated 88,000 deaths throughout
All of that volcanic
soot drifted around the Earth and reduced the warming rays of the sun the following year, thus causing the dramatic weather
Can such an event happen
again? Indeed it can and it probably will say volcanologists
Tambora is among a rim
of very active volcanoes that exist throughout the Indonesian chain of islands. There also is an active “rim of fire”
that circles the Pacific Ocean that includes many very active volcanoes along the West Coast of the Americas
and the Eastern rim of Asia.
While the Tambora eruption
is the largest in recorded history, geologists say it was dwarfed by some prehistoric eruptions. These include the largest
eruption since humans have been on the planet. This occurred about 75,000 years ago on the island
of Sumatra at what is now Lake
Toba. This volcano caused mass extinctions and science says there is
DNA evidence that the number of humans left alive were reduced to a few tens of thousands.
They say an eruption
of that size occurs somewhere on Earth every few tens of thousands of years.
The Tambora eruption
had an interesting effect on the art world in 1816. The cold wet weather forced Mary Shelley and her artist friends to stay
indoors for much of their Swiss holiday that year, during which time Shelley wrote her famous book, Frankenstein. Her friend, John William Polidon penned The Vampyre.
And the spectacular sunsets that year were recorded in the paintings of J.M.
