Few days ago a glacier flood started from western Skaftárkatlar cauldron. Due to how short time it is since last time glacier flood took place from the western cauldron a major glacier flood is not expected. No damage is also not expected from this glacier flood due to how small it is.
When the water pressure is released from the hydrothermal area that powers this cauldron, a spike in harmonic tremor is normally seen on nearby SIL station. The reason for this is unclear, with leading ideas that magma moves in the hydrothermal system when the pressure drops. The image above shows such harmonic tremor spike taking place at Jökulheimar SIL station. Eruption is not expected to happen due to this glacier flood, what happens is impossible to know for sure. Normally nothing more than just harmonic tremor spike happens.
