Teide Volcano on Tenerife, the highest peak in Spain, registered heightened seismic activity during the night of March 4-5, 2026. Over a dozen hours, at least 140 minor tremors were recorded, including 114 low-frequency events and 26 hybrid events, which differ in character from the activity observed in February. All tremors occurred at a depth of about 10 kilometers in the Las Cañadas del Teide area, with magnitudes not exceeding 1.7 on the Richter scale. Scientists from the Instituto Volcanológico de Canarias are monitoring the situation, emphasizing that such phenomena are typical for active volcanoes and there is currently no direct threat of an eruption.

Heightened Seismic Activity

During the night of March 4-5, 2026, over 140 minor tremors were recorded under the Teide volcano massif. This activity, concentrated deep under the Las Cañadas caldera, differs in character from phenomena observed a month earlier, which has drawn the attention of scientists.

Characteristics of the Tremors

The tremor series included 114 low-frequency events (long-period events) and 26 hybrid events, combining features of tectonic and volcanic tremors. All had magnitudes below 1.7 and were located at a depth of about 10 kilometers, indicating activity in the deep parts of the volcanic system.

Monitoring and Risk Assessment

The Canary Islands Volcanology Institute (INVOLCAN) continuously monitors the situation, analyzing data from the seismometer network. Experts reassure that heightened seismicity is a normal phenomenon for an active volcano and currently does not indicate direct preparations for an eruption. The volcanic alert status remains unchanged.

Teide Volcano on Tenerife is experiencing a period of heightened seismic activity, as noted by local media and scientific institutes in the first days of March 2026. During one night, from midnight to the morning hours of March 5, the seismometer network recorded a series of over one hundred minor tremors under the Las Cañadas del Teide caldera. As reported by ABC, this activity manifested as 114 low-frequency events and 26 hybrid events. La Razón points out that the character of this tremor series differs from the phenomena recorded in February, suggesting a change in the dynamics of processes occurring beneath the volcano. All recorded tremors had a magnitude not exceeding 1.7 on the Richter scale and were located at a depth of about 10 kilometers. Their epicenters were concentrated within the caldera, which is typical for activity related to the movement of volcanic fluids, such as magma, water, or gases, in the deep parts of the system. Scientists from the Canary Islands Volcanology Institute emphasize that such an increase in seismicity is normal for an active volcano and does not currently constitute cause for alarm. As read in La Vanguardia, the tremors were too weak to be felt by the island's residents, and services reported no damage. Teide, measuring 3,718 meters above sea level, is not only the highest peak in Spain but also the third-tallest volcano on an oceanic island in the world. The last eruption within the entire volcanic complex occurred in 1909 on the northwestern slope (the Chinyero eruption), while the last activity within the Las Cañadas caldera itself dates back about 1,500 years. The volcano and the surrounding national park are inscribed on the UNESCO World Heritage List.Monitoring of Teide takes place within the framework of continuous surveillance, which was intensified in the Canary Islands following the eruption of the Cumbre Vieja volcano on La Palma in 2021. The volcanic alert level has not been changed and remains at the normal, "green" level. Experts explain that periods of heightened seismicity are part of the volcano's natural life cycle and serve as an important source of data on processes occurring within the Earth's interior.
