Laguna del Maule is a volcanic field in the Andes mountain range of
Chile. The volcanic field covers an area of 500 square kilometres
(190 sq mi) and features at least 130 volcanic vents. The field gets
its name from Laguna del Maule, a lake surrounded by cones, lava domes,
lava coulees and lava flows. The field's volcanic activity began
1.5 million years ago during the Pleistocene. Three major caldera-
forming eruptions took place in the volcanic field prior to the last
glacial period. Volcanic activity has increased during the postglacial
era. In pre-Columbian times, the field was a regionally important source
of obsidian. Today geothermal phenomena occur at Laguna del Maule.
Between 2004 and 2007, ground inflation began in the volcanic field,
indicating the intrusion of a sill beneath it. The rate of inflation is
faster than those measured on other inflating volcanoes, which has
created concern about the potential for impending large-scale eruptive

Wikiquote quote of the day:
Love stands opposed to death. It is love, not reason, that is
stronger than death. Only love, not reason, gives sweet thoughts. And
from love and sweetness alone can form come: form and civilization,
friendly, enlightened, beautiful human intercourse — always in silent
recognition of the blood sacrifice.
