This page is the archive for the year 2024.
I am located in Quebec city, Canada. (FN46IS) Recently I built a
seismometer, which I operate in the basement of my house.
It took 22 months to design and build the instrument. Not a
geologist, I had to read documents and make many choices for my
first design. The instrument is in continuous operation since
February 2021. It has captured some vibrations from
distant earthquakes as well as one "local" event (M3.9). See
below the seismograms for some events that I could identify using USGS Wilber.
I have a Geiger counter in continuous operation. Its output is
periodically reported to the radmon.org
surveillance network. You can see the background radiation level
on the map. My station is labelled amichaud in the list. However you can
go directly to my (hourly) report and graph on their site by
following the link here.
Count rate below 20 CPM is normal for my staion.
Unlike other stations in this network, the numbers that is upload
from my station represent the number of counts per minutes (CPM)
that has already been averaged over a period of one hour. I only
upload one number every hour in order to save network bandwidth. I
believe this is the reason why the long time plots have a
different look for this station.
