La Palma (Canary Islands (Spain)): The number of quakes under the island has increased significantly again during the latest 24 hours, in particular the occurrence of quakes in the deeper layer around 35 km, where two shocks of magnitudes 4.2 and 4.8 were recorded today, at 11.10 a.m. and 1.23 p.m., respectively.
Both quakes were felt widely on the whole island, in particular the magnitude 4.8 event, which is one of the strongest in the current seismic and volcanic crisis. As to their meaning, it can only be speculated upon whether they signify a potential re-supply of magma at depth or perhaps the opposite, i.e. internal adjustments after magma has left storage areas below. A better interpretation of these events is likely only to follow after more time has passed and other data has been collected to study the events from an afterwards perspective.
In the meanwhile, volcanic tremor continues to follow its slowly decreasing trend as yesterday and is low when compared to previous weeks, but still significant, in tandem with continued lava effusion that resulted in the spectacular lava flows falling over the sea cliff today mentioned in the previous update.
…10 Nov:
A mesmerizing video footage of the new lava front that overflowed the cliff and reached the Los Guirres beach has been recorded today.
The video below depicts glowing lava falls entering the existing older sea delta after the new lava flow detached from the southwestern margin today.
Non si può non rimanere a bocca aperta dinanzi ad uno spettacolo della natura come questo. Nonostante la sofferenza e i danni provocati da questa lunga eruzione, l’intera isola di #LaPalma si è formata in questo modo. La cascata più bella del mondo pic.twitter.com/6jsjXkzroe
