<p>Earthquakes and volcanoes are closely associated with plate boundaries. Convergent boundaries (e.g., subduction zones) are characterized by both earthquakes and explosive volcanoes due to one plate sliding beneath another, causing melting and generating magma. Transform boundaries (e.g., the San Andreas Fault) primarily produce earthquakes due to the horizontal sliding motion of plates. Divergent boundaries (e.g., mid-ocean ridges) feature volcanic activity as magma rises to fill the gap created by separating plates.</p> Signup and view all the answers

Ground shaking can destroy ecosystems by rupturing factories and damaging habitats.

Buildings, bridges, and roads can weaken or collapse, complicating rescue efforts after an earthquake.

Earthquakes can snap water and gas pipes, halting essential services and causing shortages.

People trapped in collapsed buildings during earthquakes can suffer injuries or death.

A devastating Mw7.0 earthquake that caused pollution, building destruction, and numerous casualties in Haiti.

A series of ocean waves caused by undersea earthquakes that travel long distances.

Flooding from tsunamis destroys wetlands, forests, and habitats, harming wildlife.

Tsunamis can sweep away buildings and roads, causing significant damage to infrastructure.

A massive tsunami triggered by a Mw 7.0 earthquake in Japan, causing widespread destruction and loss of life.

Earthquakes cluster along specific geological features, often at plate boundaries.

Areas where one tectonic plate slides under another, high-risk for earthquakes.

Earthquakes that occur within tectonic plates, less frequent but dangerous.

Volcanoes are primarily located along plate boundaries, especially convergent ones.

Areas where tectonic plates separate, often leading to volcanic activity.

Tsunamis are often triggered by undersea earthquakes from subduction zones.

Ground shaking varies based on the focus depth and distance from the epicenter.

Evaluates earthquake risk based on historical data and geological features.
