La Palma volcano eruption update: earthquakes lower in numbers but becoming shallower

Time vs depth of quakes under La Palma during the past days

The latest information from the government reads that seismic activity is on the decrease while magma output remains very elevated. Emissions of sulphur dioxide have been decreasing for the 5th day in a row although remain very elevated. On the contrary, emissions of the volcanic CO2 (carbon dioxide) have increased.
All this suggests no near end of the eruption. The increase of CO2 could be an early warning sign that more magma has arrived at depth, as this gas is one of the first to escape.
Looking at earthquakes, the decrease in numbers and overall magnitudes is visible, but there is also a tendency of earthquakes to become a little shallower over the past 24 hours or so, if data are correct. Several quakes of magnitudes around 2.5-3.0 have been recorded at depths of 8-10 km (compared to 12-15 km as most others so far).
It is too early to draw conclusive interpretations, but it could either mean gravitational adjustments by gravitation of rock layers overlying the current main storage area of magma at 10-15 km depth, or the formation of new fissures underground, known as dikes, which act as pathways for magma to rise, with the potential to reach the surface at new locations.

La Palma volcano eruption update: intense ash emissions, no end in sight despite decrease of quakes

View of the eruption at La Palma this morning (image: Canarias TV live cam)
Eruptive activity remains elevated, dominated by strong ash emissions reaching up to 18,000 ft (5.5 km) altitude today, but fortunately drifting west over the Atlantic ocean and sparing the airport. Local sources reported loud explosions could be heard over night. The eruption has been becoming increasingly "ashy", or explosive, at least when it comes to what can be seen at the vents: ...
