Two small earthquake swarms occurred in January, the latest bulletin of the Peru's Geophysical Institute (IGP) reports. The first one happened between 8-9 Jan, and the second and stronger one on 25 Jan. In addition, bluish degassing (SO2, an indicator of the presence of magma) was observed.
However, IGP mentions that these signs of unrest are still weak and could be the result of increased ground-water infiltration and not likely mean a new eruption of Ubinas is nearby.
