Officials in the Canaries part of Spain, have raised the risk level of a volcanic eruption occurring in the Canary Islands, after two large tremors hit an island last weekend, the British Foreign Office has warned.
Seismic activity has been recorded on the island of El Hiero, promting officials to raise the risk level of a volcanic eruption from green to yellow.
According to the British Foreign Office, there has been low intensity seismic activity on El Hierro over the past 12 months, with over 8,000 tremors recorded, but most of them below 1.5 on the Richter scale.
Volcanoes are rated green while in a normal “dormant” state. The yellow label is given when the volcano is described as showing signs of “elevated unrest above known background levels”.
Last weekend saw two large tremors measuring 3.4 and 3.2 on the Richter scale.
Local government authorities are now monitoring the situation “very closely”, the Foreign Office said, though it added that the authorities have set the risk level of a volcanic eruption as being “very low”.
On Tuesday 53 people were evacuated from the area of Frontera as a precautionary measure against possible landslides caused by seismic movements.
Affected areas include El Lunchon, Pie Risco, Los Corchos, and part of Las Puntas and Guinea.
