Jakarta, Indonesia (CNN) -- Indonesia's Mount Merapi volcano continued to rumble and emit bursts of blisteringly hot gas and dust Sunday, as the death toll from recent eruptions pushed higher.
At least two large pyroclastic flows were spotted on the southern side of Mount Merapi during the afternoon Sunday.
A pyroclastic flow is a fast-moving burst of extremely hot gas and rock fragments. One such flow from Mount Merapi killed two people in 2006 and another killed more than 60 people in 1994.
The large clouds of gas and dust in the sky forced flight cancellations into and out of Yogyakarta. Explosions from the volcano could be heard in the suburbs of the city, some 20 kilometers (12.4 miles) away.
