Masaya volcano (Nicaragua): increasing lava lake activity

The lava lake inside the volcano's main crater (Santiago crater) not only remains active, but its activity has been gradually increasing during the past week or so.
A few days ago, between 9-10 Feb INETER had recorded a seismic crisis including 10 significant shallow earthquakes with magnitudes between 2 and 4.1, many of them felt in nearby areas, the strongest ones even in several tens of km distance. It is thought that these quakes were the result of a new injection of magma into the volcano's shallow plumbing system underneath the Masaya caldera.
Following the seismic events, elevated SO2 emissions were measured as well, reaching levels of 1500 tons / day. This observation, along with the visual impression of increased activity, is also consistent with the interpretation of new magma arriving in the volcano's conduits.
The following video shows the lava lake on 7 Feb:
