![]() Unfortunately, the official website of the National Geographic Institute (IGN) is difficult to access to review latest data, most likely from traffic overload. During the known history of mankind, no such event is known to have been witnessed. Crater of San Antonio volcano (last erupted 1677) A view of the island looking south Pico Birigoyo is the northernmost of the high volcanic peaks along the Cumbre Vieja Walls of Caldera de Taburiente Like all of the Canary Islands, La Palma originally formed as a seamount through submarine volcanic activity. Globally, major island-slope failure events that can trigger catastrophic-size tsunamis probably occur only once every 10,000 years or more. The Scientific Committee reports that there is a decrease in the number of earthquakes and in their magnitude as well, but that the land deformation has increased to 10 cm. Constructive and destructive episodes in the building of a young Oceanic Island, La Palma, Canary Islands, and genesis of the Caldera de Taburiente. It is estimated that major landslide events at La Palma occur every 100,000 years or more, and there is no evidence that the island's edifice is gravitationally unstable at present. Update on the volcanic activity in La Palma, Canary Islands. From the beginning of the seismic series until 08:00 UTC on September 13, a total of 1570 earthquakes have been detected, of which 354 were located. About 560,000 years ago, it had lost a large portion of its southwestern flank during an event referred to by geologists as the Cumbre Nueva landslide, one of the largest known of its kind. A strong earthquake swarm started under Cumbre Vieja volcano, La Palma, Canary Islands at 03:18 UTC on September 11, 2021. Nearly all volcanic ocean islands suffer massive collapse events from time to time, and La Palma is no exception. While this certainly is a potential scenario, it should also be said that it is the very worst case, and thus least likely scenario: by all known geological evidence, the current chance of a giant landslide from La Palma is still extremely slim, even should La Palma erupt in the near future. Is there a threat of a mega-tsunami from La Palma? Unfortunately, some media outlets are picking up on the potential threat of a "mega-tsunami" that could be caused by an eruption on La Palma and devastate the US east coast. Altogether, the likelihood of a new volcanic eruption continues to increase. Another worrying trend is the general tendency of quakes getting shallower. The increase in seismic activity is likely a sign that magma continues to intrude and push its way into deeper rock layers, thus causing the quakes. SO far, 5 quakes during the past 24 hours were recorded with magnitudes of 3 or more. How many quakes were there on or near La Palma Island today In the past 24 hours, La Palma Island, Spain had 2 quakes up to magnitude 1.5. 1.5 earthquake - CANARY ISLANDS, SPAIN REGION, on Tuesday, at 8:12 am (GMT +0). The coastlines of the Canaries are characterized by massive, steep cliffs and there has long been speculation that these features formed by. ![]() These islands grew over a hotspot as in the Hawaiian islands and all but one has active volcanoes. The largest so-far quake was a magnitude 3.8 quake at 11:16 local time at 10 km depth, initially reported even as magnitude 4, but later revised. The last earthquake on or near La Palma Island occurred 15 hours ago: Minor mag. The Canary Islands are a group of seven volcanic islands that lie 100 kilometers off the coast of Africa. ![]() During the past 24 hours, earthquakes have continued to pick up both in numbers and strength. The seismo-volcanic crisis is intensifying. The committee explains that the process continues and may have a rapid evolution in the short term, with the occurrence of felt earthquakes of greater intensity being expected.Earthquakes during the past 24 hours (map) and 7 days (depth vs time graph) under La Palma Island ![]() The deformation of the soil has increased reaching an accumulated value of 10 cm, very localized in the proximity of the area where the earthquakes happen. Shallow seismicity (1-3 km) of low magnitude continues, but in the last 12 hours also seismic activities at intermediate depths (4-5 km) have been detected. The traffic light will be revised in line with the evolution of the process.Īccording to experts, in recent hours the record of seismic activity has continued, verifying a decrease in the number of earthquakes and in their magnitude. The Scientific Committee of the Special Plan for Civil Protection and Attention to Emergencies due to Volcanic Risk (PEVOLCA), meeting today, has recommended to the Government to keep the volcanic traffic light in yellow in the Cumbre Vieja area, covering the municipalities of Fuencaliente, Los Llanos de Aridane, El Paso and Mazo, as it cannot be ruled out that he volcanic activity will intensify in the short term. ![]()
