Yesterday (30-January-2018) Bárðarbunga volcano had strongest earthquake since 27-October-2017. That earthquake had the magnitude of Mw4,9 (at 19:24 UTC). Two earlier earthquakes had happened but they had smaller magnitude of 3,7 (at 17:47 UTC) and magnitude 3,8 (at 18:00 UTC).

Earthquake activity seems to have stopped with last earthquake happening at 21:29 UTC. There is no change in harmonic tremor from Bárðarbunga volcano and that means no eruption. The north-east part of the Bárðarbunga volcano seems to be getting unstable with each earthquake swarm that happens. Magnitude of earthquakes happening has also increased but it is now longer between earthquake swarm. The time between earthquake swarms now can go up to several weeks. Soon after this earthquake activity started in September-2015 this type of activity happened weekly.
