Science Daily Geology
The world's smallest spectrometer has successfully measured tiny deformations of the Earth's crust, of the order of one millimeter, over a length of one thousand kilometers. Researchers used the SWIFTS spectrometer to detect these as yet poorly understood movements. Earthquakes are not the only phenomena to deform the Earth's crust. Yet slower, more continuous deformations - such as those caused by Earth tides or by slow earthquakes - are sometimes difficult to detect using large-scale techniques like GPS or seismic sensors.
