Scientists have recorded this sound made by lava oozing out of the volcano on the Spanish Canary Island of La Palma which they described as being not unlike the sound of broken glass.

The footage shows magma from the Cumbre Vieja volcano slowly advancing across a field. It can be heard making a noise that one expert likened to broken glass. The molten lava can be seen gushing flames as it oozes across the field.

The images were shared by the Geological and Mining Institute of Spain (IGME), and researcher Jose Mediato said that they “estimate the advance” of the lava to be “approximately 1 metre (3.28 feet) per minute. It sounds like broken glass, don’t you think?”

The footage was shot on the island of La Palma, which has been undergoing a volcanic eruption for over a month.

The Spanish government has said that it is going to speed up delivering aid to the island.

The volcano has so far destroyed or damaged over 2,100 buildings and over 7,500 people have been forced to evacuate their homes.

In the last few days, the eruption has intensified, with a new magma stream being reported on the southern side of the volcano’s crater on Saturday 23rd October.
