Neat program to simulate Asteroids hitting earth

[The Mullinator]

Description:
http://www.spacedaily.com/news/deepimpact-04e.html

The program:
http://www.lpl.arizona.edu/impacteffects/

Everything is scientifically accurate, and its fun to play around with. Although I noticed it is really slow to load sometimes, which is probably the result of having alot of news sites linking to it.

EDIT: Keep in mind this doesn't actually display a simulation of the asteroid hitting, it only gives the numbers like size of the crater and energy released.

You should have put something about free naked pictures in the title or something man...

Cool stuff. Another nice scientific thing is Gravity 3D, http://www.adrian.lark.btinternet.co.uk/PWGravity3D.htm simulates the colision of galaxies (with nice graphics)
Gets some nice results.

I would edit it into the title but i suspect one of the super mods would simply remove it...

I was gonna go with

"Rox0r program to sTimulate an asteroid roughly penetrating unwilling Earth"

But, such is life as to thankfuly not allow these titles.

Anyway, its certainly an interesting program...according to what i put in i would in all likelyhood be...dead.

Kinky...

Anyhow, it is a cool thinger, too bad about the horrendous loading times though.

I didnt find it too bad...however i suspect if an asteroid were about to hit, the delay in telling you how far away you need to be could leave you in a spot of bother.

whoa sick!,,, the results of a 1 km rock solid asteroid, traveling at 18 km/s, hitting at a 60 degree angle into soil and rock, (so quite steep)... when im 50 miles aways from it this is what I would experiance

Time for maximum radiation: 0.70 seconds after impact


Visible fireball radius: 12.5 km = 7.7 miles
The fireball appears 56.7 times larger than the sun
Thermal Exposure: 4.76 x 106 Joules/m2
Duration of Irradiation: 16 seconds
Radiant flux (relative to the sun): 289.3


Effects of Thermal Radiation:


Much of the body suffers third degree burns

Newspaper ignites

Plywood flames

Deciduous trees ignite

Grass ignites



Seismic Effects:


The major seismic shaking will arrive at approximately 10.0 seconds.
Richter Scale Magnitude: 7.8
Mercalli Scale Intensity at a distance of 50 km:


IX. General panic. Masonry D destroyed; masonry C heavily damaged, sometimes with complete collapse; masonry B seriously damaged. (General damage to foundations) Frame structures, if not bolted, shifted off foundations. Frames racked. Serious damage to reservoirs. Underground pipes broken. Conspicuous cracks in ground. In alluviated areas sand and mud ejected, earthquake fountains, sand craters.

X. Most masonry and frame structures destroyed with their foundations. Some well-built wooden structures and bridges destroyed. Serious damage to dams, dikes, embankments. Large landslides. Water thrown on banks of canals, rivers, lakes, etc. Sand and mud shifted horizontally on beaches and flat land. Rails bent slightly.

and not to mention the air shockwave, which breaks the windows

ARRGGHHHH im Dead ... I think? :O

that'd be a very nice screensaver!

that'd be a very nice screensaver!

They're making it into a screensaver soon too.

My computer got blacked out and crashed. Nice. :E

I just opened up that 3d gravity thing again and tried 2 million stars...it worked and was a bit jerky but it looked very cool.

Mine did too, but it used to work...

too bad, its a very good program.

 

[marksmanHL2 :)]

Hmmm, I tried mine with a few too many stars and it gave up and shut down....

 

[The Mullinator]

Wow that galaxy program is really cool. Its kind of like watching a lavalamp.

I should have gone with your title Farrow, I mean it isn't that bad.

Your Inputs:
Distance from Impact: 5.00 km = 3.10 miles
Projectile Diameter: 16093.40 m = 52786.35 ft = 9.99 miles
Projectile Density: 8000 kg/m3
Impact Velocity: 98.00 km/s = 60.86 miles/s
Impact Angle: 90 degrees
Target Density: 3000 kg/m3
Target Type: Competent Rock or saturated soil
Energy:
8.38 x 1025 Joules = 2.00 x 10(10) MegaTons TNT
The average interval between impacts of this size somewhere on Earth is 9.4 x 10(9)years
Crater Size:
What does this mean?



Transient Crater Diameter: 292.55 km = 181.67 miles
Final Crater Diameter: 615.63 km = 382.30 miles
The crater formed is a complex crater.
Ejecta:
What does this mean?



Your position was inside the transient crater and ejected upon impact

Wow.. .
