La Palma (Canary Islands (Spain)): Today, the eruption continues with steady lava fountaining from the lower vent and strong degassing and ash emission from the upper vents, but is much less noisy compared to yesterday, to the relief of people living in the area many of whom were terrorized by the extreme noise of the eruption in recent days.
The decrease of sound intensity is however not an indication of what state the eruption is in its deeper underground. It is mostly reflecting how gasses can escape and interact with the ambient air at the very surface. The decrease of eruption sound is likely due to an enlargement of the upper conduits after several collapses and other changes occurred at the vents, which now are in a more stable configuration to allow the passage of magma in a more unobstructed way. It probably has no significance as to the eruption's effusion rate, which continued to be very high. The past day's activity changed the morphology of the main cone quite a bit, by accumulation of falling material from the mountains, as well as overlapping lava flows.

...11 Oct:
The seismic activity under the island remains intense, but the quakes remain clustered in the same areas as before with no clear trend visible.
During the past 24 hours, there were 3 quakes of magnitude 4.0 or above, the largest being a widely felt magnitude 4.3 event last nigh at 10.46 p.m. In addition, there were 34 quakes between 3.0 and 4.0, and 88 quakes between 2.0 and 3.0. Most quakes occurred at depths around 10-15 km beneath the center of Cumbre Vieja, the same area affected early on in the earthquake swarm preceding the eruption, while a few, including the stronger ones above magnitude 4 occurred at depths of 35-40 km beneath the island.
