Novel tsunami detection network uses navigation systems on commercial ships

UH Mānoa researchers have equipped 10 Matson and Maersk Line ships with real-time geodetic GPS systems and satellite communications to create a network of low-cost tsunami sensors.

Accurate and rapid detection and assessment of tsunamis in the open ocean is critical for predicting how they will impact distant coastlines, enabling appropriate mitigation efforts. Scientists from the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST) are using commercial ships operating in the North Pacific to construct a network of low-cost tsunami sensors ...

Just below Earth’s surface, beneath the roots and soil, is a hard, dense layer of bedrock that is the foundation for all life on land. Cracks and fissures within bedrock provide pathways for air and water, which chemically react to break up rock, ultimately creating soil—an essential ingredient for all terrestrial organisms. This weathering of bedrock is fundamental to life ...
