Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

It’s the slip-sliding motion of plate boundaries that triggers many earthquakes. California's San Andreas Fault, where the North American and Pacific tectonic plates grind past each other with a ...

Moderate earthquakes have occurred along faults ... subduction seems to be a key factor in the transformation of the plate boundary into a subduction zone. As shown by Wannamaker and colleagues ...

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 ...

Although these earthquakes are much less common, they are due to the same forces that cause earthquakes along plate boundaries. Faults are defined by the kind of motion that happens where they are.

is forced underneath the continental plate. The force of this collision is so great that mountains are created. Earthquakes are very common at this type of boundary as the mountains are pushed ...

The Earth's plates jostle about in fits and starts that are punctuated with earthquakes and volcanic ... These convergent boundaries also occur where a plate of ocean dives, in a process called ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

Earthquakes are sometimes more challenging to prepare for than other hazards, because they happen infrequently.
