The 1815 Tambora Eruption
Mt. Tambora is on Sumbawa Island, in south Indonesia. It erupted from April 6 to 11, 1815, but the worst of this was at the end, from 10 to 11 April. The power is rated as 7 on the Volcanic Explosivity Index, making this eruption the most powerful in recorded history, four times more powerful than the 1883 Krakatoa eruption. -
The Yellow River Flood in China 1887
Many were killed in the flood which left 2 million
people homeless and as many lives that perished from the flood died in
a resulting pandemic. The total estimated recorded death figures are set
between 900,000-2,000,000 people. -
The Tunguska Explosion
It exploded with the energy of the largest thermonuclear bomb the United States has ever tested, the Castle Bravo bomb, 10-15 megatons. This is one-third the power of the largest thermonuclear weapon ever detonated, the Tsar Bomba. The airburst toppled about 80 million trees over 772 square miles of Siberian taiga, and would have registered at 5.0 on the Richter Scale. -
The Great Flood of 1931
Then the spring brought particularly heavy rains. Then the cyclone season, which usually brings only 2 storms per year, brought 10, 7 of them in July. All this water swelled the three major rivers, especially the Yellow River, and because they drain a very large, very flat area of China, somewhere between 3.7 and 4 million people were drowned or starved. -
The 1958 Lituya Bay Megatsunami
Megatsunamis were only theorized until July 9, 1958, when, in Lituya Bay, a very narrow fjord of the Alaskan panhandle, a 7.7 magnitude earthquake shook 90 million tons of rock and glacial ice off the mountainside at the head of the bay. It dropped off all at once, almost vertically, and landed as a monolith into the bay’s deep headwaters. -
The 1960 Chile Earthquake
The quake measured 9.5 in magnitude, and 35 foot high waves were recorded 6,000 miles away. Of all the seismic energy of the 20th Century, including the 2004 Indian Ocean quake, 25% was concentrated in the 1960 Chile quake. -
Typhoon Tip
Tip had one 1 minute sustained winds of 190 mph. It killed 99 people, a low number compared to some of the others on this list, but this must be placed in the perspective of a long warning before the typhoon strikes. -
The Lake Nyos Limnic Eruption
On August 21, 1986, the carbon dioxide at the bottom of the lake suddenly erupted all at once, 1.6 million tons of it, and released a cloud of carbon dioxide from the lake. This cloud, being heavier than air, hugged the ground contours, and blew out of the lake at 60 mph, went downhill throughout the area at up to 30 mph, and displaced all the oxygen in several small villages, suffocating between 1,700 and 1,800 people, not counting all their livestock. -
The Storm of the Century
The Appalachians of North Carolina, Virginia, and West Virginia received as much as 3.5 feet of snow, with drifts up to 35 feet. 300 people froze to death throughout the eastern half of the country when the electrical power was knocked out by falling trees. 100 mph wind gusts reached all the way to Havana, Cuba. -
Spencer Tornado of 1998
At approximately 8:40 p.m. (all times Central Daylight Time [CDT]) on Saturday, May 30, 1998, a violent tornado struck the small town of Spencer, South Dakota. Spencer is in extreme western McCook County, about 45 miles west-northwest of Sioux Falls. The tornado killed six people, injured more than one-third of the town's 320 residents, and destroyed most of the town's 190 buildings. Damage is estimated at $18 million. The Spencer tornado (rated F4 on the Fujita Tornado Intensity Scale, as descr -
The 1999 Bridge Creek F5 Tornado
On May 3, 1999, a tornado outbreak lasting for 3 days, began with a bang, when an F5 formed at about 7:12 PM local time. This tornado was the most powerful windstorm ever recorded on Earth, at 318 mph. It killed 36 people, and traveled northeast from Amber, OK, through Bridge Creek and Moore. Moore is a southern suburb of Oklahoma City, and had the tornado veered north into the city, it would have probably caused more deaths than any other tornado in history, and become the costliest. -
The 2003 European Heat Wave
There were at least 14,802 deaths from the heat in France alone, most of them old people in nursing homes, or in single family homes without the ability to cool off. The heat dried up most of Europe, and severe forest fires broke out in Portugal. Some 2,000 people died there from the heat. -
Hurricane Katrina
Hurricane Katrina was one of the strongest storms to impact the coast of the United States during the last 100 years. With sustained winds during landfall of 125 mph (a strong category 3 hurricane on the Saffir-Simpson scale) and minimum central pressure the third lowest on record at landfall (920 mb), Katrina caused widespread devastation along the central Gulf Coast states of the US. Cities such as New Orleans, LA, Mobile, AL, and Gulfport, MS bore the brunt of Katrina's force and wi -
The Haiti Earthquake
This earthquake was recorded at 7.0 magnitude and consequently also
delivered a minimum of 52 aftershocks (measuring 4.5+ magnitude).
At least 3 million people were terrorised by this power blasting event. It
is thought that 316,000 people had died, 300,000 injured and millions
ended up homeless. This awesome phenomena left around 280,000
building structures levelled to the ground. -
Hurrican Isaac
Once Isaac went into the gulf, it was forecast to become a strong Category 2 hurricane. However, the land interaction with Hispaniola disrupted the system and prevented a solid core from developing until just before landfall. Isaac reached hurricane strength the morning of August 28. The storm made its first U.S. landfall at 7:00 p.m. CDT that evening (0000 UTC), near the mouth of the Mississippi River. It made a second and final landfall at 3:00 a.m. CDT (0800 UTC) the next morning at Port Four
