Guest Opinion. Even without scientific tracking data, the folk who live in Oklahoma will tell you that earthquakes have greatly increased over the past several years. Why? Can the U.S. Geological ...

It's commonly assumed that earthquakes occur only near the boundaries of tectonic plates, and roughly 90% of earthquakes do happen in these areas. These boundaries include, for example, the San ...

Take yourself back to fifth-grade science for a second. You might have learned that earthquakes are caused by the sudden movement of big, underground sheets of rock, called tectonic plates. Your ...

Scientists say the answer is far more complex than a simple yes or no. Today, risk can be mapped, and early warnings can save ...

Earth's surface is broken up into large plates that rub against each other, causing earthquakes, volcanoes and large mountain ranges. But how unique is our planet's geology? When you purchase through ...

As the name suggests, an earthquake is an event that causes the earth to shake. In some cases, an earthquake can be so significant that it cracks open the ground, as well as human-made structures such ...
