Re: jumping kids cause earthquake

Trust a left wing (UNDERNEWS) publication to get it "right."

BBC: A mass jump by schoolchildren across Britain has taken place - with

no obvious effect on the equipment used to monitor earthquakes, apart
from one possible "squiggle". At 1100 BST on Friday, at least a million
children were jumping for a minute. A million children with an average
weight of 7st 12 lb (50 kg) jumping 20 times was predicted to release
two
billion joules of energy.
Scientists wanted to measure the impact on seismometers - machines used
to monitor earthquakes - but did not expect it would register more than
three on the Richter Scale.
