LAS MANCHAS, Canary Islands—They come with eagle-eyed drones and high-precision instruments. Aided by satellites, they analyze gas emissions and the flows of molten rock. On the ground, they collect everything from the tiniest particles to “lava bombs” the size of watermelons that one of nature’s most powerful forces hurl as incandescent projectiles.
Scientists from around the world are flocking to La Palma, one of Spain’s Canary Islands in the Atlantic Ocean, to take advantage of a volcanic eruption happening just an hour’s drive from an international airport and the safety of being able to work under the escort of military brigades. They are applying cutting-edge technologies to scrutinize a rare volcanic eruption from the land, the sea, the air—and even space.
