This is the recent raw output of our seismograph station. please see the Seismology section for a list of earthquakes detected earlier. Please note the date is indicated on the top left of the graph and the time is the universal time UTC.
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 (M3.7). 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.
A Count rate below 20 CPM is normal for my station.
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.

This is the completed seismometer. It was put in operation in
january 2021. A description will be posted here.
| This page is a personal web page
related to SEISMOLOGY as a HOBBY. This means
that this page has not been peer reviewed, as well
as it is not endorsed by any official or commercial
organization. In effect, it has no scientific value! I am a retired electrical engineer, and my skills are related to building and using high precision measuring instruments, building atomic clocks, and tunable lasers. I also participated to fundamental research in laser spectroscopy, a physics science called "laser cooling and trapping", and also "Bose-Enstein Condensation". I also designed and built "Atomic Clocks". These are high performance time-keepers. I built several prototypes of those. Finally I was responsable for a Microwave Metrology Laboratory. I also published my research in scientific journals. As I just explained, I had no formal training or experience in geology or earth sciences. I am only an AMATEUR in this field! If you are uncertain, please do not use the information presented on this page. On the opposite side, I should mention that I do not receive any amount of money and I do not comment on any organization, any other result or any comercial product. If you find any indication of the opposite please accept my apology and let me know so I can quickly correct the mistake. My objective is show that it is possible to build functional measuring instruments using modest resources, while having fun! |
