VOLCANO experts have begun to monitor the subterranean waters in La Palma over fears the deadly Cumbre Vieja could erupt.

A hydrogeochemical monitoring programme has been set up in a bid to strengthen the volcanic monitoring of the Canary Islands volcano.
This programme will see scientists sample subterranean waters and PH levels, conductivity, temperature and radon dissolved gas activity.
The work will be carried out three times a week in four different points of Cumbre Vieja for the subsequent chemical and isotopic analysis of the waters, as well as the gases dissolved in them.
It comes after a flurry of seismic activity beneath the surface saw red-hot magma lift the ground of La Palma.
Volcano experts will examine the subterranean waters
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.
There are increasing fears such tremors could spark an eruption from the La Palma earthquake.
Meanwhile, Involcan scientists are set to oversee the chemical and isotopic composition of the gases emanating from a nearby stream ‘Dos Aguas’ at La Caldera de Taburiente every week.
The Canary Islands has been struck by 100s of earthquakes
The stream, located near the deadly volcano, is the degassing point that registers the highest emission of helium-3 in the Canary Islands.
Experts will analyse the samples of gases for their chemical and isotopic analysis at the ITER Geochemical Laboratory.
To date, the geochemical monitoring of these gas emissions was carried out once a year.
A team from the National Geographic Institute (IGN) are monitoring the site around the volcano 24 hours a day.
The seismic activity has prompted concerns the volcano is about to erupt

Fears are growing that the deadly Cumbre Vieja volcano could erupt after a “swarm” of seismic activity hit La Palma

La Palma’s latest tremor was felt nine kilometres below ground.
There were 44 earthquakes recorded up to 2.1 magnitude hit between last 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.
