Origins: In May 2008, much of the small town of Chaiten in southern Chile was wiped out by the eruption of a nearby volcano which had long been dormant. All but a few residents fled as the Chaiten volcano buried the area under a layer of ash:
"There's no historical record on this volcano, so we have no way of knowing if the ash emissions will continue for weeks or even months," Interior Minister Edmundo Perez Yoma told reporters a day after the Chaiten volcano blew its top.
All 4,000 inhabitants of Chaiten have been evacuated to nearby towns and cities, leaving only a skeleton crew of police, military and government officials to protect the abandoned properties.
A few locals have stubbornly refused to leave their city, which looks like a ghost town in television reports.
Tonnes of dust and ash from the eruption of the Chaiten volcano poured into the night sky just as an electric storm was passing overhead.
The resulting collision created an extraordinary sight as lightning flickered around the dust cloud in the fiery, orange glow of the volcano.
Cases of electrical storms breaking out directly above erupting volcanoes are well documented, although scientists differ on what causes them.
That same newspaper also published a follow-up report with pictures of Chaiten taken in the aftermath of the volcano:
