Series of Kleinsterdbeben on La Palma

 

INVOLCAN: "Swarm quakes in active volcano normal, but they must be observed carefully"

Since Saturday, 7. October 2017, lists the Instituto Geográfico Nacional (IGN) in the area of the Cumbre Vieja La Palma a series of Kleinsterdbeben, She lasted in the Monday. Registered were local earthquake magnitude (ML) between 1.4 and 2.9 on the Richter scale at a depth between 38 and 23 Kilometers. In the night of Monday to Tuesday calmed down the situation on La Palma - There were a seaquake of strength in the Atlantic Ocean off Tenerife 4.0 on the Richter scale. After a break on Tuesday, two micro quakes on La Palma was recorded early Wednesday morning - on Friday, 13. October, the IGN reported again by 44 Vibrations. We continually update this article.

Total counted the IGN from Saturday to Wednesday 300 Micro earthquakes, of which only three in the major area between 2,1 and 2,7 ML on the Richter scale were, in the Interior of the Cumbre Vieja. In the Centre was Fuencaliente (Los Canarios); also, according to Puerto Naos in the West and Breña Baja in the East of the island, there were vibrations deep up. According to the IGN, no messages are available, that they were - felt by the population normally this is only 3 ML of the case. The national geographical Institute explained, that seismic activities of this kind on La Palma since 27 Years were no longer registered. Calm down experts, that the current "magmatic reactivation" not necessarily must result in an eruption.

The IGN will record the quakes: So far, it is the 40.

The IGN will record the quakes.

The Instituto Volcanológico de Canarias (INVOLCAN) Meanwhile commented the series: "It is absolutely normal, listed in the area of active volcanoes swarm Quake like this weekend at the Volcán Cumbre Vieja. On the other hand, this kind of operations in the Cumbre Vieja takes place every year. You must carefully follow, to assess the situation, especially since seemed quiet in the past few years. this area"

According to INVOLCAN, a "significant increase" of carbon dioxide/sulfur ratios was measured already months before the current swarm quakes on the Übewachungsstation in Fuencaliente.

La Palma: A seismic monitoring network.

La Palma: Surveillance network for monitoring volcanic activity: is reinforced through portable devices.

Tuesday, 10. October 2017: In the monitoring network of the Cumbre Vieja are three additional, Mobile seismographs and other monitoring stations. Overall the situation on La Palma has calmed down until Tuesday morning - However, the movements in the Earth's interior seem to shift: The early morning was in the Atlantic Ocean off Tenerife in 25 Km depth a seaquake with 4 ML gemesssen on the Richter scale, on the island there are two slight vibrations of 1,1 and 1,7 ML. Off the coast of The Iron (El Pinar) was a seismic activity by 2,1 ML in 24 Kilometres depth recorded and sea front Gran Canaria shortly before midnight, occurred a quake of the strength 2.8 on the Richter scale. Meanwhile will now appear in English tabloid newspapers such as the Daily Star sensation messages, After the series of Kleinsterdbeben on La Palma again that 2001 of the risk researchers Simon Day and Steven Ward praised scenario of the demolition of the West flank of the island after a volcanic eruption and a resulting tsunami theme. This panic theory was disproved long ago - more in this article of La Palma 24 Journal of the Teneguía.

The series of micro-tremors and small earthquakes in La Palma and the Canary Islands in recent days were evaluated by a panel of experts: Chaired by the Deputy Minister for environment and safety, Blanca Pérez, advised last night following specialists and organizations: Directora de Seguridad y Emergencias, Nazareth Díaz; Subdirector de Protección Civil y Emergencias, Néstor Padrón; Subdelegado del Gobierno en Santa Cruz de Tenerife, Guillermo Díaz Guerra; María José Blanco, Instituto Geográfico Nacional (IGN); Nemesio Pérez, Instituto Volcanológico de Canarias (Involcan); Vicente Soler, Consejo Superior de Investigaciones Científicas (CSIC); Inés Galindo, Instituto Geológico y Minero de España (IGME); Eugenio Fraile, Instituto Español de Oceanografía (IEO); Francisco Pérez Torrado, ULPGC, as well as technicians of the Dirección General de Seguridad y Emergencias.

The series of micro earthquakes and small tremors on La Palma and the Canary Islands in the past few days have been evaluated by a Committee of experts: Chaired by the Deputy Minister for environment and safety, Blanca Pérez, advised last night following specialists and organizations: Directora de Seguridad y Emergencias, Nazareth Díaz; Subdirector de Protección Civil y Emergencias, Néstor Padrón; Subdelegado del Gobierno en Santa Cruz de Tenerife, Guillermo Díaz Guerra; María José Blanco, Instituto Geográfico Nacional (IGN); Nemesio Pérez, Instituto Volcanológico de Canarias (Involcan); Vicente Soler, Consejo Superior de Investigaciones Científicas (CSIC); Inés Galindo, Instituto Geológico y Minero de España (IGME); Eugenio Fraile, Instituto Español de Oceanografía (IEO); Francisco Pérez Torrado, ULPGC, as well as technicians of the Dirección General de Seguridad y Emergencias.

Wednesday, 11. October 2017: In the early hours of the morning, n beOh a break of approximately 24 Hours on La Palma Fuencaliente and Mazo again two micro earthquakes from 1,3 and 1,4 ML into something more than 20 Registered kilometers depth.

On Wednesday night, the met Comité Científico de evaluación y seguimiento de Fenómenos Volcánicos on La Palma and came to the following conclusion: "Possible cause" for the more than 300 Micro quakes on La Palma is the rise of "some magma at great depth - aThis is a normal phenomenon in volcanically active areas uf anyway, Although in the past 27 Years is no longer featured". On the basis of current data predicted the professionals a "dangerous short-term scenario" in looking at the operations in the depth of the Cumbre Vieja. "However, it will continue to monitor the development of. In recent days the instruments installed on La Palma to detect seismic activity made more and more measurements of carbon dioxide emissions and chemicals dissolved in groundwater by portable devices. To strengthen a ship moves in the next few days of the Instituto Español de Oceanografía (IEO) an, to make measurements in the deep Atlantic Ocean off the coast of La Palma.

Friday, 13. October 2017: A series of micro quakes again measures the IGN - by the 44 Events remain all of the strength 2,1 ML on the Richter scale. As before, the seismic activities in a depth of play between 15 and 22 Kilometers from - so slightly higher than the previous. Informed the kanaraische volcano Research Institute INVOLCAN, dass das Red Sísmica Canaria en la Isla de la Palma with four broad band stations in use is, to further strengthen the monitoring of the Cumbre Vieja. So far no deformation of the surface in this area have been recognized according to IGN.

Micro Quake series on La Palma: INVOLCAN reinforced the stationary monitoring and measuring staff.

Tuesday, 17. October 2017: According to the Scientists were series of micro tremors of Instituto Volcanológico de Canarias INVOLCAN in the last week with their instruments on the volcano route on the road. On round 600 Points they were making measurements ascending gases and conducted geochemical analyses of thousands. In addition, INVOLCAN has the previous, reinforced fixed network of seismic and geochemical monitoring stations, as well as the GPS devices on La Palma. The Scientific Director of INVOLCAN, Nemesio Pérez, said, that the Cumbre Vieja experience the best monitoring in its history. Last time more micro quakes were measured last Saturday; currently break is on La Palma and Tenerife Kleinsterdbeben listed.

Wednesday, 18. October 2017: The Instituto Volcanológico de Canarias (INVOLCAN) announces results of mobile and stationary measurements along the Cumbre Vieja. These were to round 600 Points to around 220 Carried out square kilometers in the South of La Palma. Therefore meets daily around the "volcanic edifice" in the southern part of La Palma 788 Tons of a carbon dioxide according to INVOLCAN "normal value", CO2 emissions per day was always between 170 and 1.200 Tons, where was the invisible gas people and animals safe. The capture of carbon dioxide emissions provides information on what is happening in the deep interior of the volcanoes scientists. Typically INVOLCAN annually carries out measuring actions; because of the current seismic operations, the data to be collected on a weekly.

The Cumbre Vieja is stable, and currently there are no signs of a volcanic eruption, despite the many micro-earthquakes in the past two weeks: The INVOLCAN measurements of carbon dioxide values, rising from the volcano building, proved to be normal. Photo: INVOLCAN

Thursday, 19. October 2017: After a few days of rest was a slight tremor in the early hours of the morning again Strength 1,9 ML on the Richter scale in the South of La Palma, at a depth of nine kilometres registered.

The La Palma 24 journal updated this article continues.

The IGN has hired a video related to the development of the mini quakes on La Palma on YouTube:
