Input: Consider Input: Scientists on Monday described evidence of this bitter chapter of South American history preserved deep in an ice cap in the Peruvian Andes in the form of residue from the relentless clouds of metallic dust spewed from the mines starting in the 16th century. The mountaintop mines of Potosí in Bolivia were the world’s richest silver source. While the Incas had long extracted silver, a new processing method introduced by the Spanish in 1572 greatly increased production even as it belched lead dust and other pollutants into the atmosphere. The pollution blew over the entire region, including the Quelccaya Ice Cap some 500 miles (800 km) northwest in southern Peru. The Spanish refining process involved pulverizing silver ore, containing both lead and silver, into powder, which sent metallic dust into the atmosphere. The powder was mixed with mercury. The silver was separated by heating the mixture to allow the mercury to evaporate. Writing in the Proceedings of the National Academy of Sciences, the scientists said they drilled into the glacier at an altitude of about 18,000 feet (5,600 meters) to learn about past air pollution. The age of the ice was determined with precision because it was laid down in discernible layers caused by the annual alternation between wet and dusty dry seasons. The pollutants spawned by the Spanish colonial-era silver operations from the 16th century through the 18th century consisted mostly of lead but also arsenic and others. The researchers called it the earliest evidence of large-scale, human-produced air pollution in South America, beginning more than two centuries before the industrial revolution. The pollutants were reminders of “the sad conditions and fate of tens of thousands locals exploited in the silver mining operations during the colonial period,” Ohio State University environmental scientist Paolo Gabrielli said. “Their work conditions must have been truly terrible. Many died because of the strenuous physical efforts but it was also not infrequent that underground mine galleries collapsed, burying and killing hundreds of people,” Gabrielli said. Ohio State earth sciences professor Lonnie Thompson called the Quelccaya ice a “Rosetta Stone” for studying climate history, saying the samples also can reveal past temperatures, aridity and perhaps even the evolution of bacteria and viruses.

Output: Peruvian ice cap harbors evidence of conquistadors' avarice.


Input: Consider Input: The nation’s disaster risk management office says 1,192 cases have been identified. More than two-thirds of cases are of the more virulent pneumonic form. The office says less than 30 percent of people who have had contact with plague patients can be traced, making it more difficult to control the spread of the disease. Plague is endemic in Madagascar. This year’s outbreak is unusual because it has reached the nation’s two largest cities, Antananarivo and Toamasina.

Output: Madagascar’s plague deaths up to 124, island nation says.


Input: Consider Input: Italy’s Civil Protection officials said the quake, which struck at 3:19 a.m., was part of a swarm of some 1,000 tremors, most of them barely perceptible, linked to Etna’s volcanic eruption this week. Italy’s national seismology institute said the quake had a magnitude of 4.8 on the open-ended Richter scale and 4.9 on the moment magnitude scale, which relates to the amount the ground slips. It struck north of Catania, the largest city in the eastern part of the Mediterranean island, but no damage or injuries were reported there. The quake opened up cracks in homes in several towns, sending chunks of concrete debris tumbling to the ground. It toppled a Madonna statue in a church in Santa Venerina and broke up sidewalks and a stretch of highway, forcing it to close. Many people spent the hours after the quake sleeping in their cars. In the town of Piano d’Api, firefighters removed cracked stucco from the bell tower of the damaged Santa Maria della Misericordia church. Italy’s culture ministry said the quake damage to churches was being tallied by experts. “Etna remains a dangerous volcano, and this country of ours is unfortunately fragile,” government undersecretary Vito Crimi said as he reported 10 people injured. The most seriously injured was a 70-year-old man who fractured ribs and was undergoing surgery for chest injuries. A 71-year-old patient was being kept in hospital for observation, while others were treated and released, the Italian news agency ANSA reported. Additionally, 18 other people went to local hospitals suffering from panic attacks or shock, news reports said. One 80-year-old man was safely extracted from the rubble of his home, ANSA said, while a woman told state radio that her sister was pulled out from under a heavy armoire that had toppled. A ceiling collapsed in another house, and in other homes parts of exterior walls crumbled. Some stone walls along fields and local roads crumbled. Etna, the largest of Italy’s three active volcanoes, has been particularly active since July. In recent days, Etna’s latest eruption has been shooting volcanic ash, heavy smoke and lava stones into the air, coating roads and homes nearby with ash. A new fracture has opened near Etna’s southeast crater and lava has been flowing down an uninhabited slope. The quake was also felt in the upscale Sicilian resort town of Taormina and in other towns in eastern Sicily. The Civil Protection agency said temporary shelters were being set up in gyms or municipal buildings for people whose houses were damaged or who were too frightened to return to their homes. Similar volcanic activity on Etna has been observed many times in past decades, Andrea Billi, a geologist with the state National Council of Research, told RaiNews24. This kind of activity “can last days or weeks,” he said, “but it’s unpredictable.” Italy’s Civil Protection chief said it appeared the activity at Etna was calming down. “From a scientific point of view, we’re dealing with an isolated event,” Angelo Borrelli told Sky TG24 TV. “The technical experts tell us we’re heading toward a cooling of the lava, and we ought to expect a quiescence of the phenomenon (of earthquakes).” Some residents told reporters that after a similar quake in 1984 which killed a person, many on Mount Etna retrofitted their houses to enable them to withstand more powerful temblors. ___ Frances D’Emilio is on twitter at a href=’http://www.twitter.com/fdemilio%3c’www.twitter.com/fdemilio/a
