NASA and the National Oceanic and Atmospheric Administration (NOAA) have deployed microwave systems, including mobile very long baseline interferometry (VLBI) systems to the San Francisco Bay Area to measure the crustal motion associated with the October earthquake.
Second, Mallorca appears to be particularly well suited to the task, because neither tectonics nor isostasy - geological forces of crustal motion - over-complicate the record.
Blewitt and his colleagues monitor crustal motion using a receiver that picks up signals from the Global Positioning System (GPS), a constellation of 24 satellites orbiting Earth.
Mantle that sinks at the plate boundary flows back up farther away, pushing on the crust and causing uplift and crustal motions detectable by global positioning system, the authors found.
Strategies such as rapid local analysis of regional seismic waves, use of differential GPS measurements to detect sudden crustal motions, and shallow-water tide gauges and water pressure meters, all with continuous telemetry and real-time analysis, are critical technological approaches to nearby tsunami-warning systems.
The power from those nuclear decays--which exceeds that of 10,000 nuclear power plants--propels many dynamic features of the planet, including crustal motions that give rise to earthquakes and volcanoes and the convection of softened rock within the planet's mantle.
