The Volcanological and Seismological Observatory took a selection from a seismograph registered inside Turrialba Volcano's central crater and converted it into a sound file. The effect allows you to “hear” the volcano’s sub-audible rumbling.

Among the stolen volcano monitoring equipment: a car battery, solar panel, Trimble NetR9 Global Navigation Satellite System and a Pelican brand case.

The eruption’s most dramatic moment comes 14 seconds into the video when a rush of heat out of the crater flashes white on the screen.

Based on Monday's inspection results, OVSICORI’s experts will decide whether some of the 84 telecommunications towers on Irazú need to be relocated to safer ground.

Visitor's access to the Turrialba Volcano National Park via La Central will remain closed.

Water authorities dismissed rumors circulating on social media about water contamination by volcanic ash.

Ashes from the explosion reached several communities west of the volcano and as far as the provinces of San José and Heredia.

The biggest explosion spewed ash and vapor some 1,600 feet into the air.

The Volcanological and Seismological Observatory of Costa Rica on Monday launched a new online tool for users to track the trajectory of ash expelled by the Turrialba Volcano.

The crater of Poas Volcano expelled material 300 meters into the air at noon on Tuesday. The phenomenon, called a phreatic explosion, occurred due to a reaction between magma and water at the southern border of the lake inside the volcano. However, this was not an eruption and the volcano did not spew lava. Instead, a column of steam, gas and other materials formed and spouted out the top of the volcano, confirmed the Volcanological and Seismological Observatory of Costa Rica (OVSICORI).
