One of the biggest earthquakes ever recorded struck recently, with minimal damage, no tsunami and it barely made the news. That’s because there are two kinds of earthquakes. This earthquake happened when two tectonic plates moved past each other horizontally, while more damaging earthquakes are caused when one plate slips beneath another. This radio story explains the two types of earthquakes and how they are gradually redefining the boundaries of the tectonic plates.

Hydraulic fracturing or fracking is the process of putting liquid into shale to remove natural gas. There's concern that waste water from fracking that is put back into the ground is causing earthquakes. This public radio story explores the relationship between fracking and earthquakes.

Tsunamis are created by tectonic plates thrusting against each other and then lifting the sea floor and dropping it down, which creates a giant wave. A 2010 earthquake in Chile was caused by a shift in the seafloor. This same shift set off tsunami detection buoys and left scientists waiting for the tsunami to hit. But it ended up being small. Listen to learn more about this quake and how tsunamis are created.

Earthquakes can have far-reaching consequences not just on homes but on the power infrastructure. A 2008 earthquake in Southwest China left officials and engineers monitoring the structural integrity of enormous hydroelectric dams built to generate power. A fear of flooding caused by a cracked damn led some to wonder if they had taken the strengths of the region, its rivers and irrigation systems, and turned them into a potential threat. Listen to learn how hydroelectric power systems impact places and people.
