Earthquake

Three weeks ago Susan wrote about Mount Stromlo. The visitors centre is, of course, astronomy heavy, but there are various displays concerning other fields of science.

One of the excellent items in the information centre is a Seismometer.
Susan and I couldn't refuse the invitation



Guess who caused which tremor


If the earth moved for you at 15:10 AEST on the 11th December last year you now know who to blame.

    1. both. Altitude and mass, and landing on one's heels so as not to cushion the blow.
