2002 was a tough year for the people who live along the shores of Lake Kivu in the Democratic Republic of Congo.

It started off with a bang when the near-a-Gongo volcano erupted in January, and it tailed off with a shutter

when a magnitude 6.2 earthquake struck the region in October.

Both events devastated local communities, and their close timing struck some scientists as suspicious.

We were wondering if there could be a link, so a causality, between those two major geological events.

Christel Watier, a geologist at Pennsylvania State University.

From studying radar images of the ground,

taken before and after the January eruption,

Wattier knew that lava didn't just spew out of the volcano.

It also wedged itself into cracks in the crust,

forming what geologists call a dike.

So you can think of it as like a blade-shaped type of magma intrusion, moving from depths

toward the surface. It's very fast, a few hours, a few days, and it can penetrate tens of

kilometers of crust.

Dikes are common in rift zones like East Africa and Iceland, where tectonic forces are

slowly ripping Earth's crust apart. And they're known to cause small earthquakes right
