Washington, June 4 (ANI): Understanding of seismic background signals resulting from water movements could lead to improved earthquake and tsunami detection in the Caribbean region where 100 tsunamis have been reported in the past 500 years, suggests a new research.
The sensors detect signals from many different sources that include cars, boats and machinery operating up to several kilometers away. They also pick up the background "hum of the Earth" caused by ocean waves breaking on continental shelves around the world.
Scientists noticed that sensors on Barro Colorado recorded an intriguing wave pattern at an intermediate frequency. They suspected that this pattern could be caused by standing waves in Lake Gatun.
By installing a water-level detection meter along the shoreline, researchers confirmed that changes in the water level of the lake correspond to the unusual seismic signal.
This study provides a new method to quantify the impact of water movements as recorded by land-based seismometers.
