This evening people on the island felt an earthquake since long time. A M3.8 off the coast at the western side of the island was responsible for this. NO specific tremor on the graphs. Depth 16 km is still very deep.

Report on the seismic swarm October 2
After the passage of the night and the absence of earthquakes, it can terminate the episode seismic swarm registered yesterday on the island of Tenerife. Seismic swarm that responds to the common activity of an active volcano, but in the case of the island of Tenerife are rare, which requires monitoring.



Recall that a seismic swarm is the occurrence of a set of seismic events in a specific area over a relatively short period of time without there being associated with a major earthquake.



The rest of analysis of data from the INVOLCAN, at this time the report is as follows:



GPS stations : No deformation is attributable to this episode of anomalous seismicity. This lack of deformation may be because there is an injection of magma underground, which would make this episode of seismicity could be related to the hydrothermal system of the volcano, and not with a magmatic intrusion. We continue analyzing and observing the signals received during the day.



Gases : INVOLCAN Two teams are already in the area for a campaign swarm estimation (not visible) diffuse emission of carbon dioxide. In this regard it should be noted that the INVOLCAN 2015 registered a relative increase in CO2 emissions compared to previous years in the Northwest Ridge, without these values become extremely high.



Although this episode may be classified as abnormal, should not be cause for social alarm, because in any case there is a sequence of "action-reaction". A large number of seismic swarms appear and disappear without bringing other activity, but they are a clear example of the dynamics of an active system like Tenerife.

We will continue producing reports during the day.

IGN has located far 96 events between 14:30 pm and 19:00 pm (local time) yesterday, October 2, whose epicentral interim solutions are placed in an area between the towns of Guia de Isora , Vilaflor and Adeje. The maximum recorded magnitude of the swarm is 1 mbLg. No anomalous values recorded on the island of Tenerife in the deformation monitoring stations and geochemistry. At the moment it is reviewing and verifying the activity localized nature.

To track the activity in Tenerife is available page

Analysis Report seismic signals swarm of October 2
REPORT ON SEISMIC SWARM OF OCTOBER 02

Below are the most significant findings of the report prepared by Dr. Luca D'Auria, Head of the Functional Unit of Volcanology Volcanic Seismology Institute of the Canary Islands (INVOLCAN) on the seismic swarm Sunday October 2, 2016 are broken down into registered the island of Tenerife by the National seismic Network after thorough analysis of seismic signals.

• The spectral characteristics, distributions between events and magnitude that clearly reflect events swarm of 2 October 2016 can be reasonably classified as seismic-volcanic events long period.

• The estimated number of seismic events reported in the national seismic catalog could be underestimated. An estimate based on the spectrograms reflects the number of seismic events could have been higher than 400 events.

• After 17:58 hours individual seismic events merge into a continuous stream of seismic events lasting at least until 19:35 hours.

• The hipocentral distribution (distribution of outbreaks or depths of seismic events) is likely to be a "device" due to the geometry of the sparse seismic network of the IGN and the small amplitude of events to evaluate these processes. Seismic events are more likely clustered in a small volume.

• The depths of seismic events should be reviewed, since it could be significantly more superficial than those reported by IGN.

• The spectra shows similarities with the spectra of long-period events and tremor observed in Tenerife during the crisis sismovolcánico 2004. They also share characteristics observed in other active volcanoes in the world.

Again, we must insist on the absence of a sequence of "action-reaction" to this phenomenon as well as the need to avoid falling into unfounded alarms. The appearance of these phenomena can be as abrupt as its disappearance, without thereby an activity otherwise occur. The INVOLCAN continue to conduct relevant research for further communication depending on the signals that go recording.
