Indonesia's Mount Merapi volcano, one of the most menacing volcanoes in the Pacific 'Ring of Fire' spewed hot clouds and ash rain early on Monday.
There was no confirmation, though, of reports of fresh lava flows from the 'Mountain of Fire'.
Reports said that the mountain 'exploded' in the pre-dawnhours with lava and hot ash.
Villagerswho had not evacuated their homes gathered on roadsides along the slopes of the volcano, which rises from the plains of Indonesia's densely populated Java Island.
Theywere told to stand by for possible evacuation.
