The National Geographic Institute has recorded a new swarm of seismic-volcanic activity in Tenerife, with around 500 events in ten hours west of Las Cañadas del Teide. None of the quakes have been felt by the population.

The National Geographic Institute (IGN) has detected a new swarm of seismic-volcanic activity in Tenerife, with approximately 500 events recorded between 18:00 on July 3 and 04:00 the following day. The activity was mainly concentrated west of Las Cañadas del Teide, an area where similar episodes have already been observed in recent years.

Low magnitude microseisms and difficult location

According to data from the IGN, only three of the events have been located so far. The reason lies in the weakness of the signals, which complicates both automatic detection and the individual location of the microseisms. The joint analysis indicates an approximate depth of 10 kilometres below sea level.

The main characteristic of this new swarm is its repetitive pattern. The recorded events are very similar to each other, a behaviour akin to that observed in the seismic-volcanic swarms of February 2026, although this time they exhibit lower amplitude and energy. None of the quakes have been felt by the population.

Internal volcanic activity with no signs of eruption

Experts from the IGN interpret that the occurrence of these events is consistent with the existence of magma fluids circulating or interacting with the rocky medium at depth. Simply put: the volcanic system of Tenerife maintains internal activity, but this alone does not mean that an eruption will occur.

In fact, the available information insists that this type of seismicity, in isolation, does not necessarily imply an evolution towards other scenarios of volcanic activity. The persistence of events in the same region is compatible with the permanence of a localized active process, but it does not allow for alarmist conclusions.

This type of activity is not new in Tenerife. Repetitive seismic-volcanic swarms have been recorded several times on the Island since 2016. The latest episodes of this kind occurred in February 2026, when numerous low-magnitude events were also detected around Las Cañadas del Teide.

What does it mean for the residents of Tenerife?

For residents and visitors to the Island, the main conclusion is that there is no cause for alarm. The IGN maintains continuous monitoring of the volcanic system and, for now, no special protocol has been activated. The recorded activity is of very low intensity and does not pose an immediate danger.

That said, the people of Tenerife are accustomed to these phenomena: since 2016, seismic swarms have become a common occurrence, especially in the Las Cañadas area. The scientific community is closely following the evolution but insists that these microseisms are part of the normal behaviour of an active volcano like Teide.

The IGN reminds that, in the event of any significant change, the population will be informed through official channels. For now, it is time to continue with normal life, although with an ear tuned — so to speak — to the seismographs.
