Can Construction Sites Cause Artificial Earthquakes?

A nice piece of history. Really liked the smoked paper!

Yeah, that smoked paper was a very clever idea.

sweet ... thanks for sharing

Smoked paper seismo recording drums became all the rage around the world for many years but it was very messy to use
Then photographic paper became the in-thing. Of course it still had its problems with keeping everything dark till the paper was developed

My first seismic drum was a photographic one that came out of service from the Milford Sound station in SW New Zealand in 1991.
The New Zealand seismological Obs. replaced it with a digital recording system whose output is satellite linked back to the HQ in Wellington city.

I converted this photographic drum system to a more common ( at that time) to a normal paper and capillary - ink fed system

ohh and speaking of artificial earthquakes, I have a large construction site started up across the road from home a week ago
It's going to be several blocks of multi-story apartments and the heavy machinery digging the ground for the foundations is
causing so much noise on my seismic system during working hours ...
