A new eruptive phase marks the Turrialba since March 6 at 22:40; a slight ash emission was followed by strombolian explosions from midnight. Emissions of ashes and expulsions of glowing blocks continued until 3 am on March 7, accompanied by volcanic tremor, and reaching 1,000 meters above the crater.

From 17:40, activity resumed more energetically, with ash emissions in quantity between 18:01 and 18:20. Emissions of ashes then became passive, and ashes dispersed to the west.

LGS / Laboratorio Geofisica Sperimentale reports a major explosion at Stromboli on 7 March at 13:38 local time.

She was relayed by various photos of a plume of gray ash, rising straight.

At Shinmoedake, various satellite images complement each other to show the evolution of the plume emitted by the volcano.

Aqua Modis, a satellite of NASA, shows the trace of the plume evolving towards the south, then towards the east, under the influence of the winds.

This change in the direction of the winds is confirmed by the satellites measuring the sulfur dioxide streams, Nasa NPP Suomi and Nasa Aura OMI: SO2 emissions have taken a southern route before covering almost the entire Kyushu.
