From July 20 to today, the Geophysical Institute of Peru (PGI) has recorded and analyzed 1,522 seismic events that occurred in the Ubinas volcano, located in the Moquegua region.
According to the volcanic activity report 019-2019, explosive activity and gas emissions have decreased; however, during the last two days there has been an increase in seismic events associated with the possible rise of magma, with the consequent accumulation of energy.
All seismic events have had magnitudes less than 2.2. There have also been two volcanic explosions that released energies of 0.2 MJ and 25 MJ, which occurred on July 22 at 7:18 and 23:25 hours, respectively.
During this period of analysis, seismic signals were also recorded that would be related to magma’s rise, which have increased from 112 events, from July 20, to 406 events on July 24.
Among the recommendations offered by the PGI are not to approach a radius less than 15 kilometers from the crater; to evacuate the towns of Querapi, Ubinas, Tonohaya, Escacha, San Miguel, Huarina, Huatagua, San Carlos de Tite and Santa Rosa de Para.
In addition, avoid taking refuge under the roofs of precarious material due to the danger of collapse due to the accumulation of ashes and have at hand lenses and masks to avoid direct contact with volcanic ash.
For their part, specialists from the Vulcanological Observatory of Ingemmet (OVI) carry out the Geological Hazard Assessment of Sirahuaya, an area proposed for the construction of the camp for the evacuation of populations affected by the eruption of the Ubinas volcano.
