B612, a private foundation to detect killer asteroids. He says there are two tasks not being undertaken by NASA:
- use a space infrared telescope to map those incoming disasters
- design a system to deflect it
- Starship Troopers (1997): featuring insect aliens
- Armageddon (1998): Bruce Willis and team place a nuclear bomb on the asteroid
- Deep Impact (1998): almost the same, and this one fails
- Judgement Day (1999): Rotten Tomatoes audiences gave it a 19% rating.
- Seeking a Friend for the End of the World (2012): a comedy with Steve Carell and Keira Knightly, an asteroid named Matillda
- Iron Sky (2012): involves Nazis
3.1 miles. This killer asteroid was "only" 6.2 miles to 9.3 miles in diameter and had an impact 2,000,000 times more powerful than the Russian Tsar Hydrogen Bomba, the most energetic man-made explosion. If you've got an hour and a half to waste, here from History.com is everything you want to know about Doomsday.
1908 Tunguska Event, where the so called comet fragment had a diameter between 200 feet and 620 feet (that graphic to the right estimates 330 feet at the bottom), and has been calculated to occur once a century. Note that it has been more than a hundred years since that crash.
How far would a 300-foot tsunami flow inland? Well, all of Florida, for example:
My chapter five of SIMPLE SOLUTIONS for Planet Earth, Six Hours to Seattle, hypothesized about the potential of a megatsunami if the northeast side of the Big Island of Hawaii falls into the sea. I won't tell you what happened in my book, but feel free to glance at:
According to the U.S. Geological Survey (USGS), the Kilauea lava flow will enter Pahoa today. Click on Big Island Video News:
The lava front has actually not advanced over the past few hours, but the magma continues to build up, so the inevitable is almost obvious. Tomorrow I will speculate on whether this flow can overrun the only commercial geothermal operations in Hawaii.
Typhoon Nuri is now at 85 MPH, and predicted to attain Category 4 strength. The current path is along the eastern coastline of Japan, but sufficiently east as not to be a problem. But, ocean storms have been known to veer in strange directions.
