How to find an earthquake epicenter The ground shakes. Where's the earthquake? Highlighted concepts   Earthquakes   Waves (mechanical)   Triangulation

How fast is seafloor colliding into North America? This motion triggerred catastrophic tsunami across the Pacific in the year 1700. Could it happen again? Highlighted concepts   Seafloor spreading   Subduction   Tsunami

Hawaii's hot, but is it over a "hotspot"? The Hawaiian-Emperor seamount chain is the poster child for the existence of hotspots in the deep mantle. Is it so? Highlighted concepts   Layers of the Earth   Convection   Seafloor spreading

Is the San Andreas a threat to the San Diego region? The San Andreas Fault sits over a 100 miles east of San Diego along the Salton Sea. What if it moved? Highlighted concepts   Transform faults   Mechanical waves   Seismic simulation
