In 1963, an unexpected volcanic eruption off the coast of Iceland changed the shape of the world forever: It created the world’s youngest island, Surtsey, named after a giant in Norse mythology.

On its surface, Loch Carron is a beautiful, tranquil highland sea loch on the northwest coast of Scotland. The highlands there are home to a diverse range of wildlife, including pine martens, red deer, and oystercatchers. Hidden deep below the loch’s surface is an equally beautiful haven for starfish, flame shells, and beds of maerl, a species of coral-like red algae.

Flash floods are one of the world’s most treacherous weather events, as they occur with little warning and can cause severe damage and loss of life.
