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.
Mātauranga Māori (Māori knowledge) – produced over a time span of 1000 years, offers the longest record of New Zealand earthquakes available.
The name Rū is the Māori word for earthquakes, itself derived from Rūaumoko the deity of earthquakes (also known as Whakaruaimoko, Rūamoko, Rūaimoko, Whakarūamoko, Rūaimokoroa).
In Māori tradition, earthquakes are caused by Rūaumoko, the son of Ranginui (the Sky-father) and his wife Papatūānuku (the Earth-mother). Rangi had been separated from Papa by one of their sons Tānenuiarangi, and because they pined for one another so much, producing clouds, rain, mist, frost and snow, their sons resolved to turn their mother face downwards, away from Rangi towards Rarohenga, the underworld. When Papatūānuku was turned over Rūaumoko was still at her breast and was carried to the world below where he was given fire – te ahi komau to provide warmth and comfort for his mother. To avenge the ill-treatment of his parents, Rūaumoko constantly battles humankind, physically manifested by earthquakes and volcanoes. Although a geological interpretation of the ultimate explanations of why we experience earthquakes and volcanoes differs fundamentally from that given above, some interesting commonalities exist, most notably that earthquakes and volcanoes are caused by the same processes – heat causing earthquakes and volcanoes.
