The new analysis by an international team of researchers (Germany, Spain, Italy, Switzerland, USA- Stanford University) identified about 3,500 earthquakes, which took place at shallow depth between September and early October in the vicinity of the Castor injection platform using a combination of advanced seismological techniques applied to an enhanced waveform dataset to better understand the seismogenic process and […]
