The inner cone of the volcano, erupting on the island of La Palma since September 19, has collapsed on itself, according to the Canary Islands Volcano Institute, INVOLCAN.
A 4.8 magnitude earthquake was located this Tuesday in the municipality of Mazo, 34 kilometres below the surface, that was nevertheless felt across the island of La Palma, in some points with real intensity, as well as having been reported on the neighbouring islands of La Gomera, El Hierro and Tenerife.
This was the second largest seismic movement to have been measured so far in the Cabeza de Vaca area, in the Cumbre Vieja system.
The highest magnitude recorded, 4.9, was registered on Sunday. Tuesday’s earthquake occurred at 5:25 p.m., according to Spain’s National Geographic Institute.

The Canary Islands Volcanic Emergency Plan scientific committee (PEVOLCA) has been warning for several days that there are likely to be intense earthquakes, urging extreme caution, keeping clear of facades of buildings or street lamps, and other objects that may fall during seismic activity.
The volcano is showing no signs of rest. “At the moment we are seeing more activity, more lava and more earthquakes,” said David Calvo, Involcan spokesman.
Sulphur dioxide emission have been recorded at upwards of 5,000 tonnes per day with an ash, gas and dust plume higher than 3,800 metres. This indicator alone suggests that the eruption is far from over, and many are starting to plan on how to cope in the medium to long term, should it to continue for some time to come, as appears likely.
