Peruvian authorities have ordered the evacuation of 4,000 people living near the Ubinas volcano, which regional news outlets report has been spewing ash clouds up to 2 miles high since March 29.

According to the Andina state news agency, Agriculture Minister Juan Benites believes it will take about three days to move out the residents of two southern districts, along with their estimated 30,000 sheep, cows, horses, burros and other animals.

Peru's health ministry has received reports of eye inflammation and stomach problems from about 40 people. Meanwhile, financial assistance will be available to those impacted by the eruption, Notimérica reported.

The 18,609-foot Ubinas is Peru's most active volcano. Its most recent eruption period spanned from 2006 to 2009. Before that, the volcano hadn't had a significant event for 40 years.

Reaching an estimated 14,750 feet into the atmosphere, an April 15 ash cloud was the latest in an ongoing series of small eruptions from the volcano, according to INGEMMET, the national geologic, mining and metallurgical institute.

Ubinas is about 470 miles southeast of Lima, the Peruvian capital.

A major eruption of the volcano in 2006 forced the evacuation of thousands of residents and resulted in the loss of many livestock after they ate ash-coated grass.

Ubinas is the northernmost of three young volcanoes located along a regional structural alignment about 31 miles behind the South American nation's main volcanic front.

The upper slopes of the stratovolcano, which are mainly composed of Pleistocene-era andesitic lava flows, are nearly 45 degrees steep. Meanwhile, the 492-foot-deep summit caldera contains an ash cone with a 1,640-foot wide funnel-shaped vent approximately 62 feet deep.

Geologists have discovered at least three hundred different deposits around the volcano, which suggests explosive eruptions with more differently-composed magmas.

One of Ubina's eruptions occurred between 1000 and 1160 A.D. and produced an andesitic pumice-fall deposit which achieved a thickness of approximately 10 inches over 25 miles from the summit.
