[quote:Anonymous Coward 78592066:MV80OTA2NjY3XzkwMDc5NzczXzVFQ0E5NTNB] [quote:FeedYourHead:MV80OTA2NjY3XzkwMDc5NzQ5Xzk1MzIyRkU3] [b][b]Seismic activity shows worrying signs[/b][/b] According to a post of a geoscience page VolcanesyScienciaHoy on facebook based in Tenerife, [b]the current seismic activity points towards that more magma is moving upwards, as indicated by 3 factors:[/b] - several earthquakes appeared at depths less than 7-8-9 km; - after the 4.2 quake two days ago, there have been episodes of spasmodic tremor with many earthquakes in a row that indicate movement of magma in depth; - since yesterday, the appearance of strong volcanic tremor at around 18 Hz frequency thought to be caused by depressurization of fluids at great depth around 10 km; [b][u][u]Note: Seismic activity has only increased since this was posted.[/u][/u][/b] [b][b]If these interpretations hold, there should soon be noticeable ground uplift visible in the GPS stations [/b][/b](which, so far, is not the case). What will next happen, when this new magma pulse reaches the surface, is unknown. In the best scenario, the current conduits will continue to cope with it and the magma will erupt from the existing vents. In the worst scenario, magma could open new fissures in a different area, even after another potential pause of the eruption should it occur. In a scenario in between, new fissures might open near the existing vents, and new lava would erupt onto existing lava fields. No one can predict the future, but for sure the evolution of the eruption will be a highly interesting one and the experience intense for everyone involved, in one way or another. https://www.volcanodiscovery.com/lapalma/sep2021seismic-crisis/current-activity.html [/quote] Great post-info, thanks a lot [/quote]

Cumbre Vieja volcano or Cumbre Vieja volcanic ridge is area on La Palma Island (Canary Islands) .Potential eq swarm and eruption could trigger landslide causing widespread tsunami on Atlantic Ocean!
Update 16 th September
Deformation up to 10 cm is reported .Quakes are increasing in size and amount again.Looks like harmonic tremor is happening!
Update late 17 th September Polish Time
We are in phase of low frequency microtremors/microquakes like yesterday
Update:
People felt the eruption coming
Neighbors of La Palma "felt a noise for days". Luis Alberto Rodríguez García is Head of Engineering Operations at the Gran Telescopio Canario, in the Roque de los Muchachos de La Palma. He tells us that for days he had sounded like a vibration in his ear. And what has happened to more people. Today he is at home watching the lava run down the hillside and across the roads.
