Today (14-August-2021) an earthquake with magnitude Mw3,1 took place in Katla volcano. Other earthquakes where smaller in magnitude.
This earthquake activity appears to be normal late summer activity in Katla volcano. There was a minor increase in conductivity in nearby glacier rivers in last few days, that suggests that cauldrons have been emptying their water this summer. This is normal and happens almost every summer due to glacier melt.
