Guatemala’s Pacaya volcano erupted on Wednesday, expelling lava for several hours and prompting the country"s meteorological institute to warn that incandescent volcanic blocks could rain down on nearby towns.

Officials stopped short of ordering evacuations following the so-called strombolian eruption, explosions that consist of relatively mild blasts but eject burning cinders and lava bombs.

One of the Central American country’s most active volcanoes, Pacaya began to expel lava at dawn, creating an immense column of smoke, video footage from the institute showed.
