On the night of October 21, residents of southern Tenerife were awakened by mild tremors. Seismologists recorded a 3.2-magnitude earthquake with its epicenter in the sea, approximately 24 kilometers from the municipality of Arico. The depth of the quake’s focus was not specified, but experts note that the tremors were weak and caused no damage.
The vibrations were felt in several towns, including Granadilla de Abona, Fasnia, and San Miguel de Abona. Despite occurring at night, some residents noticed the shaking, but there were no serious consequences. No injuries or infrastructure damage have been reported.
Seismologists are urging local residents to share their observations through a special questionnaire to obtain a fuller picture of the event. The form allows people to indicate what they were doing at the time of the tremor, whether they were awake or asleep, and to describe if any objects in the house moved. This information helps experts better assess the strength and impact of such phenomena.
Interestingly, the tradition of collecting such data from the public in Spain dates back to the 18th century, after the devastating Lisbon earthquake. Since then, the survey form has changed many times, but its value for science and safety remains high.
Over the past week, more than fifty seismic events have been recorded in this area, and since the beginning of the month, the total has exceeded 140. Nevertheless, the recent tremor was the most noticeable in the past six months, although it did not reach the peak levels recorded previously.
