Space rock impacts not random 2014-11-21T05:00:00Z For comparison, the atomic bomb the United States dropped on the Japanese city of Hiroshima during World War II packed about 15 kilotons. 'Beast' Asteroid to Fly by Earth on Sunday 2014-06-06T04:00:00Z The Chelyabinsk meteor was no more than about 20 meters across, yet it exploded with over 400 kilotons of energy. Heads Up! Thirteen Years Of Asteroid Impacts On Earth 2014-04-23T13:11:21Z With a yield of 100 kilotons, it is seven times as powerful as the bomb dropped on Hiroshima in 1945. U.S. Faces Challenges Maintaining Aging Nuclear Arsenal 2014-04-01T02:13:18Z The meteor flew in at almost 60 times the speed of sound, and its breakup in the atmosphere packed as much energy as 500 kilotons of TNT, later analysis showed. The Top 10 Science Stories of 2013 2013-12-19T22:45:07.449Z The airburst explosion of the meteor packed an energy equivalent to 500 kilotons of TNT, they calculated. Chelyabinsk Eyewitnesses Help Scientists Resolve Meteor Mysteries 2013-11-06T18:15:00.363Z In the end, the blast was equivalent to about 19 kilotons of TNT going off at once, and people nearly 200 miles away felt the force or saw the flash. A visit to Trinity, where the first A-bomb was tested in 1945, turns up radiation still 2013-06-03T20:43:37Z The force of the explosion, equivalent to about 440 kilotons of dynamite, created a shock wave that shattered windows and damaged buildings, injuring more than 1,5000 people. Earth gets a rush of weekend asteroid visitors 2013-03-10T00:19:49Z The 32-second-long sound wave traveled as far as Antarctica and Greenland, boasting 450-500 kilotons of energy — making it about as powerful as 30 nuclear bombs. Meteor Blast Heard Round the World 2013-03-01T06:15:00Z The fact is, the object that exploded in a fireball over Chelyabinsk, releasing hundreds of kilotons of energy, was small potatoes. Could Another Chelyabinsk-Scale Meteor Sneak Up on Us? 2013-02-20T18:45:00.217Z It’s the most uncertain part of the calculation, but I would be very surprised if it’s less than 100 kilotons. What Do We Know about the Russian Meteor? 2013-02-15T22:15:00.343Z Infrasound data collected by a network designed to watch for nuclear weapons testing suggests that today's blast released hundreds of kilotons of energy. Russian Meteor Largest in Century 2013-02-15T18:15:00.347Z My very crude estimate of the energy of the material pegs it at a couple hundred kilotons TNT equivalent before it hit the atmosphere. Meteor fireballs across central Russia 2013-02-15T15:45:02.593Z On average, a four-meter asteroid hits Earth every year, delivering five kilotons of energy, Southwest Research Institute senior scientist Clark Chapman found in a 2004 analysis. Hundreds Reported Injured in Blast from Meteor Strike over Russia [Video] 2013-02-15T15:15:00.397Z U.S. intelligence agencies were analyzing the event and found that North Korea probably conducted an underground nuclear explosion with a yield of "approximately several kilotons", the Office of the Director of National Intelligence said. North Korean nuclear test draws anger, including from China 2013-02-13T02:26:36Z A South Korean defense ministry official said that North Korea is believed to have detonated a nuclear device with a strength of six to seven kilotons, Yonhap News Agency reported. North Korea Confirms 'Successful' Nuclear Test 2013-02-12T07:20:26Z He added that the North’s second blast, on May 25, 2009, “appeared to be more technically successful,” with an estimated yield of about two kilotons. U.S. Analysts See Opportunity if North Korea Tests Nuclear Bomb 2013-01-30T22:25:33Z Alternatively Pyongyang, in referring to a "higher level" test, may simply be aiming to test a larger device, substantially bigger than the 1 and 2 kiloton tests of 2006 and 2009. Analysis: What is driving North Korea's nuclear test plan? 2013-01-30T01:19:28Z A 5.8-magnitude quake releases as much energy as almost eight kilotons of TNT, about half the power of the atomic bomb dropped on Hiroshima, Japan. East Coast Rocked by Strongest Quake Since 1944 2011-08-24T13:52:00Z “Only about 10 kilotons of nuclear explosion capacity, and the problem is solved,” he says. On Our Radar: Deep-Sea Mining 2010-07-02T14:10:00Z They amounted to 160 kilotons annually, or 12 percent of the total. Dark Ecosystems Nurtured by Oil 2010-06-22T21:37:00Z Surprised analysts judged its strength to be less than one kiloton, or equal to less than 1,000 tons of high explosive. U.S. Analysts See Opportunity if North Korea Tests Nuclear Bomb 2013-01-30T22:25:33Z The exhaust from spaceship engines does add several kilotons of carbon dioxide to the atmosphere every year. 2009-11-24T05:00:00Z According to our estimates, we will need ten kilotons in order to have a margin of safety. The Flaming Mountain "Wouldn't take as much as a kiloton equivalent, would it?" The Galaxy Primes Globally, that kind of release amounted to 38 kilotons annually, or 3 percent of the total. Dark Ecosystems Nurtured by Oil 2010-06-22T21:37:00Z Somebody must have landed a medium missile, about twenty kilotons, against its base. Space Viking The blast we're saving to push back to safety is about three kilotons. Rip Foster Rides the Gray Planet Rick turned in time to see the side of El Viejo blow off in an explosion that made ten kilotons of fission seem puny indeed. The Flaming Mountain The blast we're saving to push to escape velocity is about three kilotons. Rip Foster in Ride the Gray Planet The more efficient fission weapons tend to fall in the yield range of tens of kilotons. Worldwide Effects of Nuclear War: Some Perspectives The nuclear yield of the detonation was equivalent to the energy released by detonating 19 kilotons of TNT. Project Trinity 1945-1946 Find a timer and connect up the ten kiloton bomb. Rip Foster Rides the Gray Planet Jumbo survived the approximately 20 kiloton Trinity blast undamaged, but its supporting 70-foot tall steel tower was flattened. Trinity site The first atomic weapon which leveled Hiroshima in 1945, had a yield of 13 kilotons; that is, the explosive power of 13,000 tons of TNT. Worldwide Effects of Nuclear War: Some Perspectives But as yields exceed 30 kilotons, part of the cloud will punch into the stratosphere, which begins about 7 miles up.
