How to Survive An Asteroid Collision


  http://www.secretsofsurvival.com/survival/asteroid.html
Have a secondary location (perhaps a cabin in the mountains or a friend or relative in a distant small town) that you can evacuate to.Since this is an asteroid you're planning an evacuation for, and not a nuclear terrorist attack, you can first attempt to evacuate by car; hopefully state official will begin evacuations days in advance so that major cities being evacuated aren't paralyzed by millions of fleeing residents.Keep survival supplies on hand that you can pack in the trunk of your car, even on the roof of your car, and if possible also in a pull-behind trailer (such as extra gasoline, considering that gas stations may be empty of gas after a massive run for fuel by hundreds of thousands of people).Pack a mountain bike for each member of your family, as well as a backpack that each person can carry on their back while riding a bike. It is estimated, however, that such hits have created many local tsunamis and brief climate changes in recorded history, without any understanding of their cause at the time

"Ironically, the easiest ones to reach and mine are also those that are most likely to one day collide with Earth and perhaps disrupt or destroy our fragile civilization. If you're musing over the same question, here's an extra bit of data from Yeomans' book: A comet streaking in from the outer solar system would typically have three times the impact velocity of a similarly sized Earth asteroid hitting Earth

About 170 km (110 mi) from the explosion, the object was seen in the cloudless, daytime sky as a brilliant, sunlike fireball; thunderous noises were heard. Thus, it seems at least plausible that large explosions of meteoritic objects were among the celestial events (together with smaller meteorite impacts, auroras, hurricanes, storms, and floods) that gave rise to belief in capricious god-like forces acting from the skies

Even so, the event caused more than 1,500 people to be hospitalized with injuries, mostly from broken glass caused by a shock wave generated when the asteroid entered the atmosphere. When the Chelyabinsk asteroid landed, a few lucky breaks prevented any deaths: it was already fractured before entering the atmosphere (which made it break into smaller pieces and burn up more easily on the way down) and the largest of the pieces that did land went straight into a frozen lake

Asteroid Collisions with Earth

Smoke from fires, dust from pulverized ejecta, and sulfate from within the objects would cause so much light loss that photosynthesis would cease for several months, a likely mechanism for causing extinctions in the ocean. When a 10 km sized object hits the surface it creates an enormous ejecta cloud which explodes outward into space, and reenters the atmosphere as countless shooting stars

Then, NASA discovered that there is an asteroid roughly the size of Texas heading towards the Earth, and when it does hit the Earth, the planet itself and all of its inhabitants will be obliterated, worse, the asteroid will hit the Earth in 18 days

That may be because cooler climates changed the types of vegetation available to eat, says Michael Benton, a palaeontologist at the University of Bristol, UK. In a review in press with the Geological Society of America, Archibald compares several rock formations from near the end of the time of dinosaurs, in Canada and the United States

Berman What Happened in Brief According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. Fundamentalists are defined as people who believe that the primary way of learning about nature should not be the scientific method, or compilation of evidence tested in different labs in different countries, but rather interpretation of ancient manuscripts, such as the Koran, the Old Testament of the Bible, the New Testament, or other ancient writings

He holds a Bachelor's degree in physics from the University of Wisconsin Green Bay, a Master's degree in the history and philosophy of science from Indiana University, and a Doctorate in neuroscience from the University of Chicago. Keller and other Alvarez skeptics look to a major volcanic event that occurred towards the end of the Cretaceous as an alternate primary cause of the extinction

Earth's Biggest Asteroid Impact Ever -Did It Occur in Antarctica? NASA Gravity Maps Point to "Yes"

The Wilkes Land crater is more than twice the size of the Chicxulub crater, which marks the impact that may have ultimately killed the dinosaurs 65 million years ago. The asteroid that hit Vredefort located in the Free State Province of South Africa is one of the largest to ever impact Earth, estimated at over 10 km (6 miles) wide, although it is believed by many that the original size of the impact structure could have been 250 km in diameter, or possibly larger(though the Wilkes Land crater in Antarctica, if confirmed to have been the result of an impact event, is even larger at 500 kilometers across)

Dinosaur-killing asteroid did not cause global firestorms: Mass extinction theory debunked

Published in the Journal of the Geological Society, scientists from Exeter University recreated the impact in a laboratory experiment to find out what the huge pulse of heat it emitted would have done to the planet. It doesn't mean the records are wrong, but maybe how they've been interpreted, we need to think about that a bit more." The scientists used the worst-case scenario for their experiments to see just how bad the pulse of heat could have been

The data was harder to gather in other continents, including Europe, and the resolution of the European fossil record is still far from that coming from North America. However, the past 20 years has seen a groundswell in European research and the continent has offered some of the best late-Cretaceous fossil samples to date

What Killed the Dinosaurs?

We now know that an asteroid at least ten kilometres across slammed off the coast of Mexico 66 million years ago, releasing 2 million times more energy than the most powerful nuclear bomb ever detonated. I think it is the Siberian Traps (?) that are relevant to this issue as the Indian eruptions were caused by the sub-continent of India breaking apart from Africa and moving north to eventually collide with the Asian continent so again IIRC that was a long time before the extinction event regarding the dinosaurs

How the Dino-Killing Chicxulub Asteroid Impact Was Found


  http://www.space.com/19681-dinosaur-killing-asteroid-chicxulub-crater.html
Some researchers have explored other possible culprits for the disaster, including other impact sites, such as the controversial Shiva crater in India, or even massive volcanic eruptions, such as those creating the Deccan Flats in India. The crash would have released as much energy as 100 trillion tons of TNT, or beyond a billion times the power of the atom bombs that destroyed Hiroshima and Nagasaki

  http://dinosaurs.about.com/od/dinosaurextinction/a/meteorite.htm
The iridium residue would have scattered all over the globe--and the massive amounts of dust raised by the impact would have blotted out the sun, and thus killed the vegetation eaten by herbivorous dinosaurs. In normal conditions, iridium is extremely rare, leading the Alvarezes to conclude that the earth was struck 65 million years ago by an iridium-rich meteorite or comet

  http://www.history.com/topics/why-did-the-dinosaurs-die-out
The Alvarezes published their findings in 1981, postulating that the thin layer of iridium was deposited following the impact of a large meteor, comet or asteroid with the earth. Scientists believe the bolide that formed it was roughly 6 miles in diameter, struck the earth at 40,000 miles per hour and released 2 million times more energy than the most powerful nuclear bomb ever detonated

These epic floods of molten rock are thought to have spanned 200,000 square miles (the size of California, New Mexico, Arizona, And Colorado combines), and in some places they are close to two miles thick. But they're still suspiciously close together, suggesting that perhaps some great collision in the solar system sent a scatter-shot of space rocks headed our way

The theory also concluded that not only was the dinosaur extinction abrupt but may have actually only taken hours as the heat from the astroid was so intense that the atmosphere (which was oxygen rich, as mentioned in the article) literally caught on fire in a ring of death that that circled the globe. It takes Way more faith to believe the world is here by accidents that are mathematically impossible anyway, than to believe in the Biblical God! Many scientists are also Christians as well and see no conflicts with their faith

Timing of an impact New findings using high-precision radiometric dating analysis of debris kicked up by the impact now suggest the K-T event and the Chicxulub collision happened no more than 33,000 years apart. For instance, dramatic climate swings in the preceding million years, including long cold snaps in the general hothouse environment of the Cretaceous, probably brought many creatures to the brink of extinction

He stresses that his proposal differs from an earlier hypothesis that the energy of the impact was focused around Earth to a spot directly opposite, or antipodal, to the impact, triggering the eruption of the Deccan Traps. Paul Renne, a professor in residence in the UC Berkeley Department of Earth and Planetary Science and director of the Berkeley Geochronology Center, re-dated the asteroid impact and mass extinction two years ago and found them essentially simultaneous, but also within approximately 100,000 years of the largest Deccan eruptions, referred to as the Wai subgroup flows, which produced about 70 percent of the lavas that now stretch across the Indian subcontinent from Mumbai to Kolkata

These observatories have identified and obtained orbital parameters for an estimated 90 percent of all asteroids in the solar system larger than 1 kilometer in diameter. An asteroid impact on land could cause vast forest fires such as the famous Tunguska event of 1908, when such an impact devastated 2,000 square kilometers of Siberian forest

End of the dinosaur age: A depiction of a Tyrannosaur as the asteroid strikes Before the cosmic explosion, many creatures were brought to the brink of extinction by dramatic climate swings in the preceding million years, including long cold snaps. The impact was clearly the final straw that pushed Earth past the tipping point.' The asteroid collision with Earth has now been dated to 66,038,000 years ago

Evolution: Extinction: What Killed the Dinosaurs?

For months, scientists conclude, dense clouds of dust blocked the sun's rays, darkening and chilling Earth to deadly levels for most plants and, in turn, many animals. Melted Rock These pieces of once-molten rock, called impact ejecta, are evidence of an explosion powerful enough to instantly melt bedrock and propel it more than a hundred miles from its origin

Asteroid killed off the dinosaurs, says international scientific panel -- ScienceDaily

The extinction wiped out more than half of all species on the planet, including the dinosaurs, bird-like pterosaurs and large marine reptiles, clearing the way for mammals to become the dominant species on Earth. Immediately after the iridium layer, there is a dramatic decline in fossil abundance and species, indicating that the KT extinction followed very soon after the asteroid hit

The asteroid, which had a diameter of about six miles struck the Yucatan peninsula and left a crater, now known as the Chicxulub, measuring 12 miles deep by 124 miles wide. The violent collision 66m years ago, which occurred in the area that is now Mexico, triggered tsunamis across the oceans, caused powerful earthquakes and released enough heat to start many fires
