Fresh Lava Arrives at Ubinas Volcano, Peru

Fresh Lava Arrives at Ubinas Volcano
Despite a recent decline in earthquakes, Ubinas Volcano erupted another ash plume on April 28, 2014. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) collected this false-color view of the area on the same day. Red in the image indicates vegetation.
 
Located in the Andes, Ubinas is considered the most active volcano in Peru, with intermittent small to moderate eruptions recorded since 1550. It had been showing signs of an impending eruption since mid-2013, highlighted by the appearance of a fresh lava dome in March 2014. Explosive activity began in mid-April, sending an ash cloud at least 4,000 meters (13,000 feet) into the air. Smaller explosions persisted through the end of April.
 
The recent eruption lead Peruvian officials to declare a state of emergency and to evacuate thousands of people and livestock (mostly llamas and alpacas). Ubinas’s frequent ash emissions are irritating the eyes and throats of thousands of local residents, especially children, according to El Economista, Peru.

Orange Alert Peru evacuates 4,000 near active Ubinas Volcano

Volcano Alert

Orange Alert

Peruvian authorities on Thursday began evacuating some 4,000 residents near the Ubinas Volcano, after detecting an increase in volcanic activity.

Peruvian news website RPP said Agriculture and Irrigation Minister Juan Manuel Banites traveled from Lima to Arequipa, the country’s second-largest city, to supervise the evacuation process.

The minister said it would take about three days to complete the evacuation procedure.

The evacuation process includes transporting some 30,000 heads of livestock to safety, the minister told the news outlet. The residents “are no longer willing to separate themselves from their belongings” because in past years when area residents were forced to abandon the animals for a long period, “they suffered huge losses,” the minister added.

Steady volcanic exhalations of smoke and ash, with plumes rising as high as 4,800 meters, and ground tremors, led authorities to declare an orange alert and move residents to temporary shelters.

Volcano Alert

A volcano in southwestern Peru called Ubinas began ejecting pyroclastic material into the sky in 2006, after over four decades of lying dormant. Recent volcanic activity has prompted officials to evacuate 60 residents of Querapi, a village near its base. The last state of emergency due to Ubinas activity occurred on April 23, 2006.

Ubinas town mayor Pascual Coaquira said the villagers were relocated Saturday, and that residents of the town of Ubinas have been distributed masks and goggles, as the building ash content in the air has made it difficult for some to breathe.

Portions of Peru lie in the Andean Volcanic Belt, which is comprised of four main volcanic zones. The stratovolcano Ubinas lies in the Central Volcanic Zone (CVZ) of the belt, a series of volcanoes formed due to subduction of the Nazca Plate under western South America along the Peru-Chile Trench.

Peru Volcano Prompts Evacuations

Ubinas is situated in southwestern Peru, and its upper slopes are primarily made up of of Pleistocene andesitic lava flows, and steepen to nearly 45 degrees. The steep walls allowed for the debris-avalanche from the collapse of the southeast flank of volcano to extend 6.2 miles. In the larger Moquegua region, including Arequipa and Tacna, there are roughly 40 volcanoes, most of which are inactive.

Coaquira added, “We are readying a shelter for refugees from the blasts. The volcano has been emitting a lot of ash all day, the people in the town (of Ubinas) are having some problems breathing.”

Ingemmet, Peru’s geological and mining agency, stated that lava had been building up in recent weeks, and warned locals they should prepare for the possibility of more evacuations. Fortunately, the type of lava from the stratovolcano is viscous and moves very slowly, while cooling and hardening quickly.

The Ubinas volcano is located in the Moquegua region, roughly 43 miles from the city of Arequipa.

Authorities Work On Contingency Plan In Face Of Increased Volcanic Activity At Ubinas, Peru

Peru: Authorities work on contigency plan in face of increased volcanic activity at Ubinas

Increased activity at the Ubinas Volcano in the Moquegua region of Peru has prompted authorities to take preventive action.

In September, dangerous silica ash spouting from Ubinas caused health problems for local residents and their livestock. Inhaling silica ash can cause gastrointestinal problems as well as respiratory damage, and prolonged exposure can damage skin and eyes. Some locals also reported experiencing severe headaches. A state of emergency was declared in the area, and one village near Ubinas was evacuated.

Now, Moquegua authorities are creating a contingency plan in order to effectively handle any serious incidents caused by the explosions at Ubinas. The volcano has been spewing ash and gases that include sulfur dioxide, which has reportedly caused people living near Ubinas to experience bothersome gastrointestinal, respiratory, and ocular problems.

According to Andina news agency, an increased level of activity at Ubinas was observed from Feb. 15 until Feb. 17. Geologists say the activity is linked to the movement of fluids inside the volcano.

Ubinas, which had been dormant since 2009, became active in September of 2013. After about a month of alarming activity, the volcano fell dormant again. In early February, the volcano became active again.
