Agung hardly gave off a puff of ash but the seismograph shows quakes and lava flowing inside the volcano. Solar conditions are ticking along. A quake and possible volcano increase is possible from 7 December. The forecast period is likely to be extended. Update. 8 December 12.00am 7 December. Molucca Sea 5.5 5.06am Nelson, New Zealand 5.0 9.30pm Eruption Sinabung. The biggest quake of the period so far has come at the Southern Molucca Sea. Solar conditions were enough to drive isolated quake activity today. An uptick in solar conditions may drive increasing quake and volcano activity on 8 December.

Agung is heating up fast. A minor ash eruption today along with harmonic tremor and increasingly large and frequent quakes at the Bali volcano. Watch out for some much bigger action at Agung on 9 December. Northern Philippines are added to Mag 6 risk locations. Possibility Mag 7 Pacific. The forecast period may be extended.

The L'Esperance Rock 6.2 was closer to home. Many minor volcanic eruptions during the later phase of the forecast period. The forecast also offered regular updates on the eruption of Agung. See Facebook/Roary Arbon. Quakes slowed on 9 December, following the big 8 December push. Volcanoes, following quakes were active. Minor eruptions at Agung and Etna. Vulcanoloigsts estimate the crater of Agung has half filled with lava in the last few days or weeks. Volcanoes are slowing on 10 December, solar conditions have faded fast today. The tourists have all left Bali and locals are left to fight it out with the elements. Locals are apparently returning to their small farms during the day but getting out at night. Cheap holidays in Bali are offered. Hot pyroclastic flows during the 1963 eruption caused thousands of deaths. New solar conditions seem possible from late 11 November but may not be very strong. Another minor eruption at Agung seems possible then. A forecast will be posted later. Aotearoa Earthquake and Volcano Forecast Service © 2013 - 2024 |
