What’s Shakin’ at the Centre of the Universe

The Centre of the Universe, located on Vancouver Island, sits atop the Cascadia Subduction Zone, where sea-floor of the Juan de Fuca plate is being pushed eastward beneath the North America continent. This process of subduction generates different types of earthquakes, including great (magnitude 8+) “megathrust earthquakes” along the plate boundary, with associated tsunami; shallow “crustal earthquakes” within the over riding North American plate; and deep “slab earthquakes” within the down-going Juan de Fuca plate. All have the potential to generate hazardous ground shaking.

SchoolShake is installing a network of Raspberry Shake seismometers in southern Vancouver Island schools to provide a real-time feed of ground shaking and earthquake locations. This program will give students and teachers a hands-on opportunity to learn about earthquakes and participate in a large-scale community science experiment that will gain new insights into the faults beneath our beautiful island.

The Centre of the Universe is pleased to be part of the SchoolShake network. Our Raspberry Shake is located in the basement of what used to be the Director’s home (now referred to as the ‘white house’).

Filter icon graphic symbol

Live view of our Raspberry Shake data. Shakes (stations) are shown as hexagons. Our Raspberry Shake, R1473 is marked "SB" in the map. Recent tremors are shown as red dots.

You can customize the view with the DataView application (below) - for a tour of the application click on the “?” button in the top right hand corner. The default view shows tracings of the latest seismic activity. Clicking on any of the traces will enlarge the trace (see below) and allow further exploration.

symbols with arrows pointing up and down and the number one in the middle
Nine-dot icon symbol, possibly representing an app grid or menu.

The arrows allow you to scale the display (tracings). If the tracings overlap, click on the down arrow to change the scale

Clicking on this symbol will change the region of the Earth that the display will emphasize - e.g., local, regional, global.

Seismograph displaying seismic activity over time, with amplitude on the vertical axis and time on the horizontal axis, showing fluctuations in seismic waves dated 2024-07-28.

Clicking on this symbol will show the intensity of the signal at different frequencies. Earthquakes will have most of their signal at lower frequencies. Below is an intensity diagram
