It's been a tense time on Iceland's Rakhianus Peninsula.

For the last few weeks, they've been seeing a lot of earthquakes.

Most of these are smaller earthquakes you can't really feel, but a lot of them, they've

been larger earthquakes, like we're talking 5.0 magnitude.

It's Friday, November 17th, and today is Science Friday. I'm SciFRI producer Charles

Bergquist. Starting in late October, the Rakhianas Peninsula has seen a lot of seismic activity.

Guest host Flora Lickman and science journalist Swapna Krishna talk about what's going on underground in Iceland.

Plus other stories from the week in science, including the tale of an exoplanet where it rains sand and a wayward toolbag in space.

It's all in this week's Cyfry News Roundup. Here's Flora.

Earthquakes have been rumbling through the peninsula for the last few weeks with increasing frequency.

And this week, they were seeing hundreds of earthquakes a day.

Listen to this.

This. That sound is a translation of seismic data made by the Earth Tunes app, run by Northwestern University.

Each of those snaps and pops represents an earthquake.

That 30-second clip captures the earthquake activity of about eight hours last Friday.

Here to tell us what's going on is Swapnakrishna, a science journalist based in Philadelphia.

Welcome back to Science Friday.

Thank you so much.

What is happening with all these earthquakes?

Yeah, so this peninsula is in southwest Iceland, and scientists think a volcanic eruption might be imminent in the area.

And so part of the reason for this is this area sits on the mid-Atlantic ridge, which is the

boundary between the Eurasian and North American tectonic plates, and they're drifting apart
