Meteor Craters from Around the World part 2

A series of videos I put together from pictures and other videos that I've found around the internet and on youtube. These are meteor craters from all around the world, some younger than you might think. Did you know that there have been at least five large meteor strikes in the last 100 years? Tunguska you may know about, but there have been a number of other events.

for some of the events in these videos. One of the most notable must be the impact in poland (the same yield estimate as for the russian impact before that, which had a crater much bigger).

I'm having doubts about the converter I used. It is very inaccurate on smaller blasts. I may re make and re upload these.

I was one time flying VFR in Arizona and used Barringer Crater as a checkpoint.

great idea to create these videos, you certainly have some nice, and rare footage in your archives.

the energy density of a meteor can be up to several hundred times that of TNT as well. One "rick" is the kinetic energy of an object where its mass is equal to the energy contained in an equal mass lump of TNT. This is at 3 km/s. Meteors are usually at lower speeds than 20 km/s but can reach 30. Comets can reach up to 80 km/s. and kinetic energy is approximately 0.5mv^2.

it is pretty easy to derive the yield and size of impactor from simple scaling relationships. The crater diameter is generally around 20x the diameter of the impactor. Energy density is often around 10 times that of TNT (so 42 gigajoules per ton approximately). This of course varies, depending on whether the impact is in solid mountain, or in sand dunes, material, angle, velocity of the impactor and so on, but that is the general idea.
