Monday was the Boston Marathon bombing. On Wednesday, it was a massive explosion at a fertilizer factory in West, Texas.
What is the world coming to?
USGS says the explosion was equivalent of Magnitude 2.1 earthquake, and adds "Explosion at fertilizer factory at West, TX. The magnitude measures only the ground motion, not the air wave, so is substantially less than the true size of the event."
So far, up to 70 people dead, over 200 injured (40 critically), 100 houses and buildings completely destroyed.
