On May 27, 2020, a seismic swarm rattled the municipalities of Vilaflor and Guia de Isora on the eastern slope of the Teide Volcano.

In total, 70 volcano-tectonic quakes hit the area within 8 hours. The maximum intensity was a M2.9 tremor at 03:51 A.M. GMT. Is an eruption brewing at Teide?

On May 27, 2020, the Canarian Seismic Network operated by INVOLCAN, has registered a seismic swarm located between the municipalities of Vilaflor and Guia de Isora at depths between 7 and 12 km.

In total, 70 events have been located between 01:46 A.M GMT (02:46 Canarian Hour) and 12:31 P.M. GMT (13:13 Canarian Hour). The maximum magnitude has been 2,5 for a registered event at 03:51 A.M. GMT (04:51 Canarian time). All events have features that allow them to be clearly classified as volcano-tectonic.

The series of earthquakes occurred slightly away from the area most frequently affected by seismicity during last year in Tenerife. The maximum magnitude observed, although small (Ml= 2,9) is the strongest in Tenerife since the event of January 6, 2017, located under the Teide.

What’s behind the swarm?

The swarm possibly reflects a process of pressurization of the volcanic-hydrothermal system, linked to the injection of gases of magmatic origin into the system.

This process, which began in 2016, is also manifested by an increase in the diffuse emission of carbon dioxide (CO2), emanations not visible to the human eye, in the crater of the Teide since last November 2016.

However, there is no significant ground deformations. This may show that the swarm isn’t linked to a superficial magmatic system.

In the short term, it cannot be excluded that more small-magnitude earthquakes may occur, even strong enough to be felt by the population. On the other hand, damaging earthquakes can be ruled out.

Officials say the seismic swarm at Teide is of scientific interest but isn’t a sign of an impending eruption… What were they saying about the virus and the pandemic? Yes, you get it…

Teide Volcano

Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.

Teide’s most recent eruption occurred in 1909.

The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano because of its history of destructive eruptions and its proximity to several large towns.

Be ready and get prepared for the next Teide eruption, even if officials say the volcano isn’t a threat or a risk. Always better to be prepared for the right moment, I guess… More volcano news on Strange Sounds and Steve Quayle. [El Diario]

  1. could you idiots reporting the news inform the idiots listening and reading to “where the hell you are talking about”… Is it that hard to mention what country
    or area you are talking about. Worthless information as usual !

  2. Tenerife is the largest and most populated island of the eight Canary Islands. It is also the most populated island of Spain, with a land area of 2,034.38 square kilometres and 917,841 inhabitants at the start of 2019, 43 percent of the total population of the Canary Islands

  3. Thank you for clarifying the location! The context suggested it but not totally sure. Some of us have had busy lives NOT involving geography that much for the past 40+ years …

  4. DOES ANYONE LISTEN TO THE LORD JESUS??he has told all his family the volcano will erupt and send a BIG TIDAL WAVE across the ocean to the americas,THERE will be two of them coming,IT WILL TAKE 4 and 1/2 hours to reach the east coast,several hundred feet high,IF YOUR still on the coast when they come,YOU’LL be meeting him…face to face…

    • For the past 65 years I’ve lived within ten miles of the Atlantic Ocean. I currently live in Charleston, SC. My emergency plan is to stay ‘prayed up’ and keep looking up.

  6. We have our Intel inside USA with fires, are manufactured by owners of businesses that were supposed to be bankrupted or no money was left for them to survive. All those businesses were touched by the owners and relatives to get money back from insurances company and then deal with money later on to see what they want to do reopen it or change locations. Again most of businesses are on fire by the owners. Recently all owners upgraded their insurances for businesses it needs also investigated. Yes things may not seems as you see , we are in twilight zones. We have INTEL this violence riots are continues as long as businesses gone under due to SARS-COVID-2.0
    and due to looses that no one would pay, now fires are set by owners to get money back , we saw many interviews live middle of night the owners said we were open suddenly torched our factory. Who the hell under middle martial law is open for business? This needs to be looked at more any one can pick it up. There is no more peaceful demonstrations any more all are going to be violent fires set by owners or relatives under masks paid or non paid for collecting insurance money ? what do you think?
