A cascade of lava spilling into the Atlantic ocean from the Spanish island of La Palma has been photographed by the European Space Agency (ESA).

The lava from the volcanic eruption extends the size of the coastline and covered about 20 hectares when the image was taken, the ESA says.

It was captured by the Copernicus Sentinel-2 mission on September 30th.

The eruption began when a crack opened in the Cumbre Vieja volcano on September 19th, throwing plumes of ash and lava into the air.

Lava then flowed down the mountain and through villages engulfing everything in its path. Around 5,000 residents in four villages were evacuated, and hundreds of homes and buildings destroyed.

By September 28th, the six-km long lava flow had reached the Atlantic on the island’s west coast. Clouds of white steam were reported where the red-hot lava hit the water in the Playa Nueva area, the ESA says.

The Sentinel-2 mission is based on a constellation of two identical satellites, each equipped with a high-resolution multispectral imager fitted with 13 spectral bands to monitor changes in the Earth’s land and vegetation.

The image was processed using a shortwave infrared channel to highlight the lava flow.

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
