The huge spike in activity beneath the surface has seen red-hot magma lift the ground of La Palma.
Experts investigating recent tremors – which saw nearly 400 mini earthquakes in 15 hours over the weekend – found the earth has lifted up to 3.5cm in the past year.
And, after four days of inactivity, La Palma recorded another tremor overnight when a 1.9 magnitude quake was felt nine kilometres deep.
Fears continue such tremors could spark an eruption from the La Palma earthquake – known as Cumbre Viega.
Experts have previously claimed the volcanic explosion could destroy the island, sending a slab of rock into the Atlantic Ocean, sparking a megatsunami.

A report put together by the University of California and University College London said if Cumbre Vieja were to come alive the western flank of the mountain could tumble into the ocean.
A team from the National Geographic Institute (IGN) are monitoring the site 24 hours a day.
They released a Twitter update this morning on the latest tremor but pleaded for calm.
Director of the IGN in the Canary Islands, María José Blanco, said current activity in a volcanically active island like La Palma was something “we have to get used to”.
She said: “The population doesn’t have to be alarmed, but trained and used to the fact that this can happen” because there is a volcanic surveillance network to detect these episodes.
Ms Blanco added they maybe increased monitoring brought in.
She said: “We have the permits to install everything.
“IGN continues with the work of improving, increasing and expanding the La Palma volcanic monitoring network.”
The latest termor follows a huge flurry over the weekend.
There were 44 earthquakes recorded up to 2.1 magnitude hit between Friday at 1.52pm and Saturday to 4.17am.
But experts believe the total number, including ones too small to be located, within the seismic storm was 352.
