IGN: Tenerife Seismic Activity Does Not Increase Volcanic Risk
The National Geographic Institute has confirmed that recent minor seismic activity in Tenerife is typical for the island's volcanic system and does not indicate an increased risk of eruption.
Recent seismic activity in Tenerife does not mean the island’s volcanic risk level has changed, according to the National Geographic Institute (IGN). While the agency is closely monitoring two areas that showed activity over the weekend and early Monday, they confirm these events are typical for an active volcanic system.
On Saturday, April 11, sensors near Izaña recorded 16 seismic movements, 11 of which were precisely located. These were volcano-tectonic earthquakes with magnitudes between 1.0 and 1.9, occurring at depths of 3 to 10 kilometers. This activity is similar to patterns observed in the same area between May and November 2025.
Separately, early Monday morning, the monitoring system detected activity in the western part of Las Cañadas del Teide. This included two low-frequency pulses and several small hybrid earthquakes. While the automated system flagged 38 events, experts were only able to manually confirm three, which occurred at depths of 12 to 13 kilometers.
The IGN noted that none of these tremors were felt by the public due to their low intensity. Experts also emphasized that these signals do not indicate an imminent eruption and there is no increased danger to the island. Because the tremors were so small, the current data on their exact magnitude and depth remains provisional and may be updated as the institute continues to analyze the information.
