Karangetang (Indonesia) - Report for 6 February-12 February 2019 - NEW

On 8 February PVMBG reported that lava from Karangetang?s Kawah Dua (North Crater) continued to advance over 3.5 km down the Malebuhe River drainage on the NW flank into the ocean.
Levees had formed at the margins channeling the lava down the middle of the flow.
Avalanches from the edges of the flow generated brown and gray plumes.
A lava delta was building out into the ocean and generating a dense steam plume.
Drone footage acquired on 9 February showed that the flow was about 160 m wide where it crossed a road (about 210 m from the coast) and about 140 m wide at the coast.
Seismicity remained high.
The Alert Level remained at 3 (on a scale of 1-4), and residents were warned to remain outside of the 2.5-km exclusion zone around the N and S craters, and not enter within 3 km WNW and 4 km NW.
