All ash elevations are in km above sea level (a.s.l.) and times are converted to UTC. For more from USGS on volcanoes, see
http://pubs.usgs.gov/gip/volc/text.html#types . Note that eruptions are of "volcanic cinders (red or black), volcanic ash (commonly tan or gray), and volcanic dust".

SPECIAL NOTE
The Moon as a Weapon, p.2
Compare:
The mass of the Earth is approximately 6,000,000,000,000,000,000,000,000 (6E+24) kg/(1.3E+25 lbs.)
http://science.howstuffworks.com/question30.htm
The Moon has a mass of 73.8E+21 kg/159.9E+21 lbs.
The biggest hydrogen bomb ever tested (by the Soviets) yielded 50 megatons, or the equivalent of 100,000,000,000 lbs (100E+9) of TNT.

So is the Moon is safe for Earth? Next week: Orbital Mechanics.
