Taiwan (Hualien) earthquake April 2024: tectonic setting

In the morning of April 3rd 2024, #Taiwan was hit by a M 7.4 earthquake and aftershocks. The country - and indeed the #faultzone itself have histories of earthquakes. Find out about the tectonic setting and a bit of a puzzle. This video is part of The Shear Zone channel where you'll find more films on #geology, #tectonics # and other recent #earthquakes.

Would love to see some videos of this nature and related about the Cascadia subduction zone. I tried finding an analysis of earthquake depth today with no luck. There's been a lot of research on it so I must be looking in the wrong place.

Thank you Prof Butler. Really good explanation and very quick to make it!

Those two plates are trying to tie themselves up in a pretzel

As a geologist that has been doing mining and hydro for the last 25+ years, this was a nice concise structural refresher.

Thanks Rob... As current as it gets quake wise. It sounds like Taiwan is both geologically as well as politically, between a rock and a hard place. Would the Longitudenal Valley Fault Zone consist of Schuppen like structures? Or am I just shoehorning in a vaguely related term from my deep lower mantle memory...

Dear Prof. Rob, That's an brilant prsentation

I am amazed how rapidly the Phillipine plate is moving.
