Masaya Volcano, Nicaragua. Footage of the churning lava lake inside the Santiago crater, a small volcano within the enormous Masaya Volcano, Nicaragua. Rocks are seen falling into the lava lake. Masaya is a caldera: its cone collapsed after a violent eruption thousands of years ago, leaving a gigantic basin with steep sides. The basin now contains several small stratovolcanoes (conical volcanoes), including the live volcano, Santiago. Volcanoes are formed when molten rock (magma) forces its way up through weak points in the Earth's crust. They are especially common near the edges of continental plates, where the crust is weakest. | |
