La Palma island and the eruption: satellite view of the eruption cloud

Yesterday's satellite image shows beautifully the circular eruption plume from the ongoing eruption, generating concentric wave patterns due to the absence of wind in combination with the rising column of ash and hot air from the eruption.

It also shows a typical weather pattern for the island: The normal north-east trade winds near the ground caused a cloud barrier east of La Palma, leaving the west side free of clouds. Above a first inversion layer, located between 600-800 m elevation, there is a southeast wind current from the Sahara, carrying extra dust (in addition to the ash from the volcano), known as "Calima", which is confined again by a second inversion layer at around 1600 m.
During this weather, the temperatures on the coast are moderate (last night near Tazacorte: 18-19 deg C) and above the lower inversion layer and the upper layer, where many villages are located, the temperatures are much higher: last night, in the caldera, they reached 31 deg and 26-28 deg on the NW flanks where we are currently located.

The eruption continues with no significant changes during the night. The upper vents produce pulsating fountains of ash and some lava, while the lower vents erupt more degassed lava in low lava fountains or directly as lava flows. Read all
