exciting news for seismologists everywhere. My greatest ever achievement, a functioning geophone made from Lego, is now available to purchase from mindsetsonline.co.uk , also available a usb 24bit digitiser.

It would be amazing to consider a ringed Earth ... and new research suggests that almost half a billion years ago, that make have happened! Did the Earth destroy an asteroid that strayed too close and end of with a ring? I explore this cool idea: www.discovermagazine.com/planet-earth...

The Earth Might Have Been a Ringed Planet Long Ago

The gas giants in the outer solar system are the homes to ring systems today, but almost half a billion years ago, our planet may have had a temporary ring, too.

Hey, post-glacial rebound earthquake! ⚒️🧪

The modellers among us worked hard to relate the period of the seismic oscillations to the period of a possible seiche (sloshing wave) in the fjord. Could it be modelled? (Yes!) Could it be sustained? (Yes!) @seismo-steve.bsky.social made this awesome video showing our colleagues' efforts!

In September of last year, a mysterious sesmic signal swept around Earth ringing for an astounding nine days. Now scientists finally discovered the source: a mega-tsunami in a remote Greenland fjord triggered by a colossal rockslide! My latest for Science Mag! ⚒️ www.science.org/content/arti...

A tsunami in a remote fjord rang Earth like a bell for 9 days

Scientists trace strange seismic signal to landslide that triggered sloshing, 200-meter-tall waves in Greenland

Yes, the colours on the model show wave heights but it would be spectacular to see the initial and subsequent waves. www.youtube.com/watch?app=de... Very lucky there were no vessels in the fjord.

Last year, an immense but brief outburst of seismic energy was soon followed by a long hum that made the world ring. Finding its cause took 68 scientists and an assist by the Danish military.
