Fogo volcano (Cape Verde): new eruption

A new eruption started at the volcano this morning around 10:00 local time. The aviation alert was raised to red due to possible ash emissions that could harm aircraft in the area.
Not much detail about the eruption is so far available, but a strong thermal anomaly was detected on satellite data, suggesting the presence of lava at the vent, perhaps in the form of lava fountains. Typical eruptions of Fogo start with lava fountains / strombolian activity that build a new cone, followed by lava flow effusion.
According to news articles, strong precursory seismic activity since yesterday night caused many people to sleep outside their houses. Approx. 1000 people have been evacuated from the Fogo caldera.
Increased CO2 emissions had been detected from Fogo during the past months already, an early sign that fresh magma was rising under the volcano. When measured in March, CO2 emissions had increased from averages of around 90 to more than 300 tons per day.
