Blasting at 6 mm/s


These people are quite shaken up at 6 mm/s. The Ministry would allow over 12 mm/s, and in most places they go to 15. Earthquake damage to housing actually starts at 500 mm/s. A strong earthquake on solid rock most likely can't exceed 100 mm/s at moderate distances.

However, in the zone of a 'super pulse', it's 1-2000 mm/s.
