After a year that has seen concern about potential voicano eruptions in Iceland, Italy and Bali, volcanologists on the Canary Islands have been asked to work out whether the island of La Palma is facing an imminent eruption.

The experts have been asked to monitor activity on the island, which saw 400 tremors in 15 hours over the weekend, according to The Express.

Close to Tenerife, Cumbre Vieja (meaning "Old Summit") previously erupted in 1949 and 1971. After the recent tremors - and a 3.5cm rise in the earth over the past year - scientists have been asked to monitor the volcano, amid fears that an eruption might lead to an earthquake and possible tsunami. 

So now a special hydrogeochemical monitoring programme has been set up in a bid to improve volcanic monitoring of the volcano. Scientists will take samples of subterranean waters and PH levels, conductivity, temperature and dissolved gas activity three times a week at four locations in Cumbre Vieja.
