Igneous or magmatic rocks The most primitive rock type forms when magma (molten rock) solidifies - either inside the earth (plutonic rocks) or during volcanic eruptions (volcanic rocks). A short overview.
Introduction to Plate Tectonics The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
La Palma Volcano Special We offer a short-notice tour to see the eruption on La Palma in a small group guided by a volcanologist (Evelyne Pradal - English and French speaking geologist.)
