http://youtu.be/Ya6BHS_Xd84 The Geographic South Pole isn't a permanent spot on the map—it actually sits on a massive ice sheet that drifts roughly 33 feet every single year. To compensate for this constant creeping ice flow toward the Weddell Sea, scientists at the Amundsen-Scott Station must physically relocate the pole marker every New Year's Day. If they skipped this vital annual adjustment, the official marker would slowly slide completely away from Earth's true rotational axis. During a special mid-summer ceremony, researchers unveil a custom-designed brass and copper marker to pinpoint the exact new location, while the old one is officially retired to a display cabinet.

http://youtu.be/ps8fHvhbyiY A powerful fault line hidden deep beneath the Pacific Ocean has been producing a series of magnitude 6 earthquakes, drawing the attention of geologists and earthquake monitoring agencies worldwide. Scientists are studying the unusual seismic activity to understand what is happening far below the Earth's surface and whether these events could signal larger geological changes ahead. The region sits within one of the most active tectonic zones on the planet, where massive plates constantly shift, collide, and generate powerful earthquakes. New research and seismic data are helping experts map this hidden fault system and uncover the forces driving these repeated tremors. Discover what makes this underwater fault so important, why magnitude 6 earthquakes keep occur...
