Shiveluch (Kamchatka): KVERT reported strong fumarolic activity with small amount of ash and an incandescence of the dome blocks and hot avalanches associated with this process. The volcano's lava dome remains in a very active state.
The surveillance cameras observed an ash plumes that reached 32,808 ft-49,212 ft (10,000 m-15,000 m) altitude.

Piton de la Fournaise (La Réunion): OVPF reported that the eruption stopped on 16 February at 14:12 local time. No earthquake has been recorded since the eruption stopped.
A satellite image from 16 February at 10:35 local time shows a thermal anomaly at the level of the eruptive vent. This anomaly as well as the persistent puffs of gas during the morning on 16 February indicated a weak residual subsurface activity until the final shutdown of the tremor at 14:12 local time.

...17 Feb:
The first eruption of the volcano in 2020 lasted less than a week, from 10 - 16 Feb 2020.
The volcano observatory did not find any evidence of eruptive activity since the abrupt drop and cessation of volcanic tremor on 16 Feb at 14:12 local time, which was therefore declared as the end of this eruption.
No significant earthquake activity has been recorded since the eruption ended, only a thermal anomaly persists at the vents, caused by hot gasses still escaping from there. This anomaly as well as the weak tremor signal still present in the morning of 16 Feb indicated a weak residual subsurface activity until the final cessation of the tremor at 14:12 on 16 Feb.
