The slightly elevated rockfall activity yesterday ended at about 4.30pm. The level of rockfall and pyroclastic flow activity was then low until about 3am when another period of slightly elevated activity began. This is still ongoing and is characterised by regular rockfalls and small pyroclastic flows. The cloud is low again today.
There were several small long period earthquakes overnight some of which triggered small rockfalls.
Further pyroclastic flows are expected, and it is possible that the hot pyroclastic flows and surges could travel even further. The flows move extremely fast and cannot be outrun. The revised zones A and B, which include Tuitt's, Bramble, Bethel, Spanish Point, Farms, Harris and Trants, are extremely dangerous and the authorities and MVO strongly advise that nobody should go into this area at all. The public are reminded that while Bramble Airport remains operational for the time being, it is open only for essential travel purposes - people not travelling should not visit the airport, and parents in particular are urged not to take their children to the airport just for the outing. The sirens will be tested today between 3pm and 6pm.
