Updated 19 January: The Canarian Government has convened its scientific committee – Comité Científico del Plan Especial de Protección Civil y Atención de Emergencias por Riesgo Volcánico (Pevolca) – to meet on Monday to consider yesterday morning’s tremor in the faultline in the sea between Tenerife and Gran Canaria, now confirmed at 4.2 magnitude and the largest earthquake measured in the archipelago in the last 30 years.
Anyone who might be concerned will hopefully be reassured by the post about the educational and evacuation measures in place in the event of an eruption or need for evacuation HERE … but bear in mind that there is absolutely no suggestion that this activity is anything other than normal, even if at the edges of what has been recorded routinely.
Original post 18 January: Emergency services say that they received around 20 calls shortly after 6.30 this morning from locals in the municipalities of La Matanza, Tacoronte, La Laguna, Güímar, Santa Cruz de Tenerife, Candelaria, Fasnia, Arico and Granadilla who literally felt the earth move. At the moment the authorities say that what was felt was part of the normal seismic movement in the channel between Tenerife and Gran Canaria, is provisionally registered at 4.3 magnitude, and that further investigation will of course take place. For the moment, however, there are no incidents to report, and this is a channel in which is there is regular seismic activity which is normal for an active though quiescent volcanic archipelago.
