La Palma: 'Lava bomb' speeds down Cumbre Vieja volcano

Watch the video to see a ball of solidified molten rock, also known as a "lava bomb", as it speeds down the side of the Cumbre Vieja volcano on the Spanish island of La Palma.

The volcano has been erupting since late September. Its eruptions have forced thousands to evacuate their homes and destroyed buildings and plantations.
