The National Geographic Institute (IGN) have just informed that the geodesic network of stations installed on La Palma, which measure the curvature of the earth’s surface, has detected an elevation of more than 10 centimetres in the last 24 hours, towards the south in the stations closest to the volcano as activity is at a shallower depth.
In contrast, a slight deflation is maintained at the most remote stations, possibly related to deep seismicity, notes the IGN, as the amplitude of the volcanic tremor signal, the ‘noise’ made by the eruption itself, is maintained at medium to high levels, with intensified pulses.
This morning, Tuesday, the plume of sulphur dioxide (SO2) being emitted by the eruption reached 2,000 metres (2kms) in height at 8:00am, an hour after a 4.2 magnitude earthquake recorded at 7.05am.
Since their previous report, the IGN have recorded 184 earthquakes in the area affected by the volcanic reactivation of Cumbre Vieja, 17 of which have been felt by the population.
80 have a magnitude equal to or greater than 3.0 mbLg, and five earthquakes have been located at depths around 30 kilometres, whereas the rest of them have been measured at a shallower depth, around 12 kilometres.
