Upgrading jAmaSeis on the Raspberry Pi

Updating the version of jAmaSeis on a Raspberry Pi is a pretty straight forward exercise. jAmaSeis will perform a check from time to time, when a new version is available a pop up window will appear detailing the new version.

Upgrading is not necessary for uploading you stations image to the University but it is a good practice to keep the software up-to-date. If you are sharing your data with IRIS you will need to upgrade your software.

To update visit the IRIS website, http://www.iris.edu/hq/jamaseis/ from the Raspberry Pi using the Web Browser. Download the Linux jAmaSeis_x_x_x_x.sh to your Downloads directory.

Download latest jAmaSeis

Make sure to close jAmaSeis before updating. You will need to open a Terminal prompt and make the script executable. It’s important to run the script with the sudo command, this will upgrade the currently installed version of jAmaSeis.

Run jAmaSeis installer

Commands to run, replace jAmaSeis_x_x_x_x.sh with your downloaded version. You can use tab completion to fill in the filename by typing jA then pressing the tab key. The shell will fill out the rest for you.

cd Downloads
ls
chmod +x jAmaSeis_x_x_x_x.sh 
sudo ./jAmaSeis_x_x_x_x.sh
Enter the seismometeruser password to start the installer

Follow the installer prompts to complete the upgrade.

Assembling the case for your TC1

Below you find detailed instructions on the assembly of an aluminium and plexi-glass case for the TC1 seismometer. It was successfully tested by an 11-year old volunteer from Oratia District School (thank you, Hayden!)

Click on the images for more detail and a short description.Once assembled, it is recommended to fasten the completed case to a wall.

 

Thank you Mark,  Trevor, Steve and all others from the Science and Engineering Workshop!

Setting up your new seismic station

If all is well, you received a TC1 seismometer, a computer with everything installed, and a flat-packed protective case.

    • Unpack the computer and TC1. Plug the power, the usb keyboard/mouse and ethernet cable into the computer.
    • Connect the TC1 to the computer with the USB cable in the USB port marked “TC1.”
    • Hook the magnets to the slinky attached to the inside of the top cap of the TC1.

  • Lower the magnets into the tube so that the bottom magnet is inside the copper damping ring and the top magnet is inside the coil.
  • Level the magnets with the three knobs on the legs. The goal is to make sure the magnets do not touch the rings.
  • Also, make sure the top of the magnets are flush with the top of the copper ring and coil, respectively. Small adjustments to the vertical position of the magnets can be made with the knob on the top lid.

Now turn on the computer. All the necessary software to display your seismic data will turn on automatically. The most recent versions of the station software include a standard slide-show that explains the TC1, has acknowledgements, a map of NZ latest earthquakes (data courtesy of geonet), and the seismic data from your station.

You can turn the slide show on and off in the bottom
control panel. Just go the bottom of the screen with your mouse, and the button will appear.

Next, we assemble the case, and place it over the TC1. We recommend fastening the case to a wall, or to the floor.

Congratulations! You are up and running! If you have any questions or comments, please feel free to contact us using the mailing list on the left.

Soon, you will see your first signals!

How to get involved with Ru

If your institution wants to get involved in the Ru network, there are a couple of things to consider. In terms of hardware, you will need a public place (library, or foyer) with easy access to:

  1. power,  and
  2. a wired internet connection

The hardware you need consists of:

  1. the TC1 seismometer,
  2. a dedicated computer,
  3. a case to protect the device from bumps.

Maybe most importantly, you need a Station Manager.  A teacher would be the most logical choice, but it could be  a parent. The station manager does not need to be a seismologist, but  someone who can field basic questions from students,  solve small problems with the station, and relay bigger ones to us for troubleshooting.

 

To give you an idea on how your class project may go, you can watch this video.

Through the generosity of the Foundation of the Society of Exploration Geophysicists, we have some scholarships available for the most suited institutions. If you want your institution to be considered for a scholarship, write us.

SeiSNZ is now Ru!

We are very proud to announce that our team now includes Dan Hikuroa from Nga Pae o te Maramatanga, New Zealand’s Indigenous Centre of Research Excellence. There are several projects around the globe that do seismology in schools, but to celebrate New Zealand’s unique cultural heritage and its natural expressions such as earthquakes and volcanoes, we decided to name our network “Ru”, short for Ruaumoko, The Maori God of Earthquakes and Volcanoes.
