SANTIAGO (AFP) - Southern Chile's Puyehue volcano was calm Sunday, one day after raining down ash and forcing thousands to flee, although the cloud of soot it had belched out still darkened skies as far away as Argentina. A light drizzle rained down on the volcano Sunday, helping to mitigate the effects of the airborne ash somewhat, while the mountain appeared to go quiet one day after having rumbled to life. "The city awakened in calm," said Marcelo Cascon, mayor of Bariloche in neighboring Argentina, which had received a large deposit of volcanic ash spewed out from Puyehue on Saturday.
