La Palma volcano update: Strongest-so-far quake at magnitude 5.1 at only 26 km depth under island

This morning's magnitude 5.1 event, which hit at 7.27 a.m., is the strongest-so-far tremor under the volcano since the seismic crisis followed by the ongoing eruption began in September.

It was felt all over the island, and if the depth is correct of only 26 km it deviates significantly from the depth layer around 35-40 km, which has been where other stronger quakes in the range of magnitudes 4.5-5 that have occurred so far.
This could be due to new magma intrusion into intermediate layers at this depth. It will be important to see whether it will be followed by an increase of lava activity in the near future (several hours from now possibly).
