Sulfur dioxide emissions
First estimated amount of sulfur dioxide (SO2) emissions occurring in the plume reached to a 6000-9000 tonnes/day provided by the AEMET.
Lava flow discharge rate
New measurements were also made to provide new parameters of the lava flow discharge rate. The average lava flow discharge rate at the current eruption site is about 0,7 kilometers per hour.
Thermal anomaly
According to MIROVA Detection System a very high thermal anomaly (2828 MW) was detected in satellite images yesterday, but it decreased to 1509 MW today.
Precautions
Around 5,000 people have been evacuated from the high-risk areas. The efforts are focused on reducing infrastructural damage.
The La Cumbre Vieja volcano erupted after 8 days of intense seismic crisis yesterday afternoon as two eruptive fissures opened in the area of the Montaña Rajada mountains accompanied by lava fountains erupted from at least 7 individual vents.

The surface continues to inflate, which is a sign that more magma is being stored underground that (can erupt) erupts at the surface - the existing paths are not large enough. The volcano might choose to either enlarge them or create new ones. ... Read all
