The Turrialba volcano of Costa Rica had a violent burst in the early hours of last Thursday morning (May 12), spewing a flurry of ash, gas, and smoke over 3 kilometers (1.8 miles) out the top of its summit. The smell of sulfur also filled the air for miles and miles around.

“It was a single explosion but a really strong one. This means that there was high pressure inside the volcano,” Javier Pacheco, a volcanologist with the Volcanological and Seismological Observatory of Costa Rica, told Tico Times.

Costa Rica’s National Seismology Network has released this video, showing off the magnitude of the eruption through the eyes of an infrared camera.
