Cumbre Vieja is an active although dormant volcanic ridge on the volcanic ocean island of La Palma in the Canary Islands, Spain, that erupted twice in the 20th century – in 1949, and again in 1971. As many ocean island volcanoes by nature, the La Palma Island is prone to catastrophic flank failure events. Blog. Cumbre Vieja has recently been rocked by dozens of seismic movements of low magnitude between 1.5 and 2.7. Cumbre Vieja volcano is one of the most active in the Canaries and has had historical eruptions in 1585, 1646, 1712, 1949, and 1971. The Cumbre Vieja volcano forms the southern third of the island of La Palma. Using a geologically reasonable estimate of landslide motion, we model tsunami waves produced by such a collapse. Cumbre Vieja Volcano (CVV, see Figure 1b) is the one growing the most rapidly [Carracedo et al., 1999], which hence may pose the largest threat of a flank collapse. Bejenado volcano (left-center) is located in the large breached caldera of Taburiente volcano (background). How to create a webinar that resonates with remote audiences; Dec. 30, 2020. 140 EARTHQUAKES have been detected on the Island of La Palma under the Cumbre Vieja volcano. The maximum magnitude observed was m1.8. Cumbre Vieja is the fastest growing volcano among all the Canary Island volcanoes (Carracedo et al., 1999) and, hence, may pose the largest threat of a flank collapse, i.e., a large scale subaerial landslide that would propel a large volume of rock into the ocean. La Palma and the adjacent island of El Hierro are the youngest islands in the Canarian archipelago and are presently in a “shield building” phase of activity comparable to the present activity of the island of Hawaii (Carracedo et al., 1998; Carracedo et al., 1999b-this volume). Eruptions at Cumbre Vieja Volcano in 1677 occurred at a strombolian vent located at the northern part of the large cone, and a group of spatter vents on the SW slope of the San Antonio volcano. A computer model has been designed to show the way the tsunami will build after the volcano, called Cumbre Vieja, erupts on La Palma, at the western end of the Spanish island chain. La Palma earthquake swarm Dec. 23-24, 2020 The latest swarm started Dec.… The elongated volcano is oriented N-S and has been the site of numerous historical eruptions. Mega-tsunami hazard? The Canary Islands Volcano Institute (Involcan) has registered more than 60 low-magnitude earthquakes since 4:10am yesterday on the Cumbre Vieja volcano, on the island of La Palma. Generally the scenario goes like this: The Cumbre Vieja volcano on La Palma falls into the ocean, sending disaster-movie-like waves throughout the Atlantic Basin. An unstable volcano in the Canary Islands, located off the northwestern coast of Africa, is directly threatening most of the Caribbean. Cumbre Nueva Ridge (right) was formed by a large-scale collapse. It had erupted previously in 1949. View of the Cumbre Vieja volcano Getty Images. Mega-tsunami hazard? Department of Ocean Engineering, University of Rhode Island, Narragansett, RI, USA Walls of water 300 feet high would travel to the US at the speed of a jet. The first major one occurred in October 2017, followed by another seismic crisis in February 2018. They have … By Strange Sounds -Dec 27, 2020 Several swarms or seismic series have been recorded on the Cumbre Vieja volcano in La Palma / Canary Islands in recent years. We conclude that although uncertainties still exist regarding the timing of a future flank collapse of the Cumbre Vieja volcano, the various lines of evidence presented … Meanwhile, 2020 has already given us 4 seismic swarms. The Ash Cloud. Explore the Cumbre Vieja Volcanic Ridge when you travel to Canary Islands - Expedia's Cumbre Vieja Volcanic Ridge information guide keeps you in the know! According to Involcan, this new seismic swarm does not represent a danger for residents or visitors to the island given the small magnitude and depth of the earthquakes. Teneguia Volcano. 2 The volcano is located on the island of La Palma in the Canary Islands Prezi’s Big Ideas 2021: Expert advice for the new year Near- and Far-field Tsunami Hazard from the Potential Flank Collapse of the Cumbre Vieja Volcano Jeffrey C. Harris1, Stephan T. Grilli´ 1, St´ephane Abadie 2 and Tayebeh Tajalli Bakhsh1 1. The figure shows the epicenters of this new swarm in red and the recorded seismicity located on the Cumbre Vieja volcano over the past 3 … However, with recent seismic movements ranging between 1.5 and 2.7 on the Richter scale, scientists have set up a special hydrogeochemical monitoring program to monitor the volcano . The first major one occurred in October 2017, followed by another seismic crisis in February 2018. The western flank of the Cumbre Vieja volcano would slide down westwards into the Atlantic ocean. We then used FUNWAVE-TVD to simulate trans-Atlantic wave propagation until they reached the Guadeloupe archipelago where we used SCHISM to assess their final impact. Geological evidence suggests that during a future eruption, Cumbre Vieja Volcano on the Island of La Palma may experience a catastrophic failure of its west flank, dropping 150 to 500 km³ of rock into the sea. San Antonio Cone was the main vent of the 1677 eruption. Explore the great outdoors at Teneguia Volcano, a lovely green space in Fuencaliente de la Palma.
