La Palma records an earthquake of intensity ‘V’
According to the National Geographic Institute (IGN), since Sunday November 28 at midnight last until today Monday 29, more than 50 seismic movements have been recorded on the island of La Palma. One of them was magnitude 5, the first earthquake to reach the intensity of “pure” V on a XII scale, since the eruption of the Cumbre Vieja volcano began on September 19.
During a first automatic reading, the IGN recorded two almost simultaneous seismic movements of magnitude 4.8, but, according to one of their seismologists, Itahiza Dominguez, one of them was a reading error of the system. Automatique. The false reading has since been revised to magnitude 5, which occurred at 8:35 am, located in the town of Mazo, at a depth of 35km.
Itahiza Dominguez explained that the latter is surely due to the fact that the energy of this seismic movement was emitted more upwards than laterally. This is the reason why this last earthquake was felt in La Palma but not on the neighboring islands of the Canary archipelago.
Earthquakes are measured by their intensity, in terms of their effects on people and objects, on a scale from I (not felt) to XII (totally devastating). The current level V (strong) assumes that the earthquake is felt inside buildings by the majority and by some outside.
As reported by IGN, observers would have felt a strong jerk or strong oscillation of the entire building, room or furniture, with the hanging objects oscillating considerably. Dishes and glassware could collide with each other and small, unstable or poorly supported items. may move or fall, as reported by 20minutes.es.
