This Indonesian volcano spews boiling-hot mud

Scientists recently published a paper in the Journal of Geophysical Research: Solid Earth about the historic Lusi mud volcano. This volcano is spewing boiling-hot mud.

It's called Lusi and it lives on Java island. Lusi has been erupting for 11 years. On average, it erupts enough mud to fill 32 Olympic pools each day. It's the most destructive ongoing mud eruption in history. Lusi has buried villages in up to 130 feet of mud. It's forced 60,000 people from their homes.

Until recently, Lusi was a mysterious force of nature. Scientists couldn't explain why the volcano continues to erupt, until now. Turns out, Lusi has a secret network of underground channels. One of the channels leads straight to a nearby magma volcano.

For years, this magma heated the ground under Lusi. The heat caused the mud to boil and produce gases. These gases built up pressure over time. Then, in 2006 an earthquake triggered the first eruptions. The magma continues to heat sediment under Lusi.

So, Lusi isn't going to stop erupting anytime soon.
