What's Shakin' right now?
when there is not an earthquake, the shake maps are fun to look
at. The museum is close to Necanicum Drive and built on sand
fill. The seismometer is very sensitive, so it records
movement from trucks driving down the street or museum personnel
moving furniture! We may also get some shaking from the ocean,
depending on the day.

little traffic or movement until after 8:00am. Throughout
the morning we see small traffic vibrations. In the afternoon,
museum personnel began rearranging furniture in the area around
the seismometer - those big squiggles are just us, not earthquakes!
