The earthquake that struck near Valdivia, Chile, in 1960 was the most powerful temblor in recorded history. The quake left about 2 million people homeless.

Environmental Hazards
The environmental hazards you face depend on where you live. For example, if you live in northern California you are more likely to be impacted by a wildfire, landslide, or earthquake than if you live in Charleston, South Carolina, but less likely to be hit by a hurricane. This is because the physical conditions in each place are different. The active San Andreas fault runs through California and causes regular earthquakes, while the warm waters transported by the Gulf Stream can intensify a storm heading for South Carolina. These environmental hazards shape human activity regionally. Building codes in California require builders to meet standards set to minimize structural damage in an earthquake and coastal cities have building code to reinforce roofs and walls to resist a storm’s high winds.

Earthquake
The surface of the Earth is made up of tectonic plates that lie beneath both the land and oceans of our planet. The movements of these plates can build mountains or cause volcanoes to erupt. The clash of these plates can also cause violent earthquakes, where Earth’s surface shakes. Earthquakes are more common in some parts of the world than others, because some places, like California, sit on top of the meeting point, or fault, of two plates. When those plates scrape against each other and cause an earthquake, the results can be deadly and devastating. Learn more about earthquakes with this curated collection of classroom resources.
