The most active – and the most visited – volcano on earth is Kilauea in the Hawaii Volcanoes National Park, seen by 3 million people every year. Along with its counterpart Piton de La Fournaise, on the French island of Reunion in the Indian Ocean, it is characterized by extraordinary lava flows that travel great distances through a spectacular landscape. Together they form the focus of this dazzling photographic essay by two renowned photographers. This is an invitation for readers to share an amazing glimpse into the heart of these red volcanoes, and a timely reminder that the Earth itself is alive and fulfilling an agenda of its own.
