According to the specialist, the number of explosions, whose Gas and ash emissions reach a height of less than 1,800 meters above the craterthey can also be considered at the yellow alert level, which means lower risk. The decision to change the alert will be defined in the first weeks of January.
Likewise, he indicated that, given the reduction in explosions and intensity, it is an opportune time to carry out environmental impact studies such as studies of soil, air, grasslands, land, livestock and moreconsidering that within 8 km of Sabancaya there are approximately 40 families that live off livestock in the ranches like Cajamarcana, Sallalli, Mucurcaamong others.
He environmental impact study of 8 years of eruptionwould correspond to institutions such as Health, Agriculture, Weapons, among others, but also studies from public and private institutions such as universities.
