Heightened Seismic Activity Observed Under Mount Teide in Tenerife

This morning, a significant seismic event was detected in the Las Cañadas del Teide caldera, located on the island of Tenerife. The event has drawn the attention of both local authorities and geological experts due to its unusual characteristics.

According to specialists from the Canary Islands Seismic Network, the long-period (LP) seismic event was recorded at approximately 8:20 AM, occurring at a depth of around 11 kilometers beneath the earth’s surface. Such depth is notable as it provides insights into the geological processes occurring below the surface of this iconic volcano.

While traditional seismic measurement techniques do not yield precise magnitudes for LP signals, researchers have estimated that the event reached a magnitude of approximately 2.2 on the Richter scale. This estimation is significant, as it helps in understanding the energy release associated with the seismic activity.

The Canary Islands Volcanology Institute (INVOLCAN) has highlighted the importance of this event, stating that it represents the largest amplitude of an LP event ever recorded on the island. This record-breaking amplitude indicates a potentially heightened level of geological activity beneath Mount Teide, which is a dormant stratovolcano and the highest peak in Spain.

In recent years, Tenerife has seen a series of similar LP events, alongside six swarms of hybrid signals detected in nearby regions. However, the amplitude of today’s seismic event sets it apart from previous occurrences, suggesting a possible escalation in the volcanic system’s dynamics.

LP seismic events are typically linked to the movement of hydrothermal fluids, which include hot water and gases circulating within the volcanic system. These movements are part of the ongoing pressurization of the magmatic-hydrothermal system beneath Mount Teide, a phenomenon that has been under continuous observation since 2016. Understanding these processes is crucial for assessing the volcano’s behavior and potential hazards.

Experts have been quick to clarify that while this type of seismic activity indicates movement beneath the surface, it does not imply an imminent volcanic eruption. Instead, it serves as a vital indicator of internal changes within the volcanic system, which can provide valuable information for future monitoring and research.

Authorities are maintaining a vigilant watch over Mount Teide, ensuring that both residents and visitors are kept well-informed about the situation. They emphasize that there is currently no immediate cause for concern regarding volcanic activity. However, they encourage public awareness and adherence to restricted areas within Teide National Park to ensure safety.

As the situation develops, ongoing monitoring will be crucial. The Canary Islands Seismic Network and INVOLCAN are committed to providing updates and insights into the seismic activity, helping to ensure that the community remains informed and prepared for any changes in the volcanic landscape.
