Transient gravity changes are expected to occur at all distances during an earthquake rupture, even before the arrival of seismic waves. Here we report on the search of such a prompt gravity signal in data recorded by a superconducting gravimeter and broadband seismometers during the 2011 Mw 9.0 Tohoku-Oki earthquake. During the earthquake rupture, a signal exceeding the background noise is obs...
Tsunamis are normally generated by underwater earthquakes. The earthquakes are normally easily detected by seismographs. However, the earthquake may not always generate a tsunami. Further, the severity of the earthquake is not linearly related to the severity of the tsunami. The tsunami may be detected by a deep-sea pressure transducer communicating through a surface rider buoy, through satelli...
In this paper, we discuss a possible combination of Earthquake Early Warning (EEW) and Neo-deterministic Seismic Hazard Assessment (NDSHA), propose new warning model, EEW2.0. The aim is to provide differentiated alert various end-users based on the results seismic hazard assessment evaluation. implementation such system contains three basic steps: (a) classification “potential cause hazard” in ...
The unpredictability in time of seismic activities and the dependence tectonic movements on a multitude factors challenges specialists to identify most accurate related methods avoid catastrophes associated with hazards. Early warning systems are critical reducing negative effects case an earthquake magnitude above 5 MW. Their precision is all better as they corroborate transmit more informatio...
Fast and accurate magnitude prediction is the key to success of earthquake early warning (EEW). However, it difficult significantly improve performance by empirically defined characteristic parameters. In this study, we have proposed a new approach (EEWNet) based on deep learning predict for EEW. The initial few seconds P-wave recorded single station without any preprocessing used as input EEWN...
