These movements, driven by the heat within the planet’s core, create a myriad of geological features, including mountains, volcanoes, and, importantly, lakes. Tectonic lakes, formed by the direct influence of tectonic … Read more

Unraveling the Earth’s Tremors: A Comprehensive Look at Types of Earthquakes The Earth, despite its seemingly solid exterior, is a dynamic and restless planet. Beneath its surface, immense forces are constantly at play, shaping the landscape and releasing energy in the form of seismic waves. These waves, often felt as tremors or violent shaking, are … Read more
Most of the knowledge we have about Earth’s deep interior comes from the fact that seismic waves penetrate the Earth and are recorded on the other side. Earthquake ray paths and arrival times are more complex than illustrated in the animations, because velocity in the Earth does not simply increase with depth. Velocities generally … Read more
