NASA‘s Juno Mission recently spotted powerful volcanic activity on Jupiter’s moon Io. The hotspot is said to be larger than Lake Superior (which, if you didn’t know, is 31,700 square miles).
The source of Io’s torment: Jupiter. About the size of Earth’s Moon, Io is extremely close to the mammoth gas giant, and its elliptical orbit whips it around Jupiter once every 42.5 hours. As the distance varies, so does the planet’s gravitational pull, which leads to the moon being relentlessly squeezed. The result: immense energy from frictional heating that melts portions of Io’s interior, resulting in a seemingly endless series of lava plumes and ash venting into its atmosphere from the estimated 400 volcanoes that riddle its surface.

Celebrate literacy with the children in your life with NYPL Sings!
Through this album, we focus on singing as a wonderful way for parents, caregivers, and librarians to bond with children and help them become self-confident, curious, and intrepid learners with a lifelong love of reading. Use this webpage to learn about the important developmental skill each song represents and how easily you can reinforce these skills every day with your child.
Have you ever heard of an icequake? Icequakes occur when groundwater freezes, causing the ground to tremble similar to a small earthquake. The phenomenon is somewhat rare, but recent cold blasts through the Midwest have folks feeling the freeze in more ways than one.
Because the Midwest isn’t a tectonic hotspot, detection relies on citizen scientists – primarily through the Raspberry Shake! u/dulce1021 has a great post on Reddit on how Raspberry Shake confirmed icequakes in Madison, WI.
TLDR: Icequake confirmed!
This is going to get nerdy, so strap in and prepare to be underwhelmed.
You won’t be surprised to learn that there aren’t a ton of professional high-grade seismometers installed in Wisconsin and streaming real-time data. However, there is a decent network of low-cost citizen science seismometers that we can use. These devices are called Raspberry Shakes and you can buy one yourself for a couple hundred bucks and stream live data to their site, which is where I went looking for data. Wouldn’t you know, in a city as nerdy as Madison, there were a handful of Raspberry Shakes with data to look at.
