The Search for What Shook the Earth for Nine Days Straight
Manage episode 446815330 series 3610709
In a recent article from Quanta Magazine by Robin Gerorge Andrews, scientists explore a large rock-ice avalanche in Greenland that triggered a megatsunami and produced a strange, continuous hum detectable by seismometers worldwide for nine days. Initially, researchers investigated various explanations, from ice sheet vibrations to volcanic activity, to account for the hum. Eventually, they determined that it originated from a standing wave, or seiche, generated by the tsunami's unique interaction with the fjord's shape, causing the water to oscillate for an extended period. This discovery underscores how climate change can lead to unexpected geological phenomena and highlights the importance of scientific curiosity in unraveling Earth's mysteries.
