At the moment, each Ru seismic station is sending a screenshot of its recordings to the University of Auckland. There are several ways to see this screenshot. For example here, and if you click on your station on our network map. If your screenshot is not up-to-date (and remember, seismologists’ clock is in UTC, not local time!), it is worth checking a few things:
Is the computer associated with your station working? If you see signal being recording on the screen, the answer is “yes.”
Is the signal you see on your screen “live?” In other words, is the latest part of the wiggles current? If not, make sure you hit the “now” button in jamaseis. Do you see new wiggles being recorded?
Next, open a browser on the computer of your station. Can you surf the web? If not, make sure you have a working ethernet connection. Because wireless connections are prone to timing out, we recommend wired connections. A reboot may prompt you to (re)make the connection to the internet, or you may need an IT person to help you.
If you have power (1), you are “live” (2) and you have an internet connection (3), but your screenshot is still out of date, please contact the Ru team at the university of Auckland.
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.
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.
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.
chmod +x jAmaSeis_x_x_x_x.sh
Enter the seismometeruser password to start the installer
Follow the installer prompts to complete the upgrade.
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!
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.
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.
Head of Science at Rangi Ruru Girl’s School, Keith Machin, wrote a wonderful article about Rangi’s first experiences in the Ru network of TC1 seismometers. In the article, Keith also proposed 10 lessons for teaching the topic of earthquakes.
