Krisuvik activity 2 day swarm

Have been looking at the latest activity under Krisuvik with a little more critical eye in the wake of the revelation that the swarms at Hengill were caused by water injection into heated strata by the power station people. Having compared and contrasted the screengrabs I took at the time, there's a definite similarity in depth and intensity.

As the Krisuvik field is close to the large lake called Kleifarvatn, I find myself wondering if there's currently some form of leakage into the fault complex that might be a causative factor. According to it's Wikipedia page entry the lake has leaked periodically since a big quake in 2000. Wonder what the water levels have been doing recently?
