In the frame of the SISPyr project the feasibility of an Earthquake Early Warning system (EEW) covering Pyrenees is being studied. First of all, the analysis of the existing seismic stations shows that the SISPyr realtime network may be used as a base of a Pyrenean EEW despite that some difficulties exist to its implementation that should be solved. The exploration of an important Pyrenean wave...
Earthquake early warning studies are shifting real-time seismology in earthquake science. They provide methods to rapidly assess earthquakes to predict damaging ground shaking. Preventing false alarms from these systems is key. Here we developed a simple, robust algorithm, Authorizing GRound shaking for Earthquake Early warning Systems (AGREEs), to reduce falsely issued alarms. This is a networ...
Earthquake is one of the most destructive natural phenomena which has human and financial losses. The existence of an efficient prediction system and early warning system will be useful for reducing effects of destroying earthquake. In this research, the soil temperature time-series data, obtained from three meteorological station, using three filters (Fourier, Wavelet and Logarithmic Different...
We demonstrate a flexible strategy for local tsunami warning that relies on regional geodetic and seismic stations. Through retrospective analysis of four recent tsunamigenic events in Japan and Chile, we show that rapid earthquake source information, provided by methodologies developed for earthquake early warning, can be used to generate timely estimates of maximum expected tsunami amplitude ...
[1] The real-time earthquake information system (REIS) of the Japanese seismic network is developed for automatically determining earthquake parameters within a few seconds after the P-waves arrive at the closest stations using both the P-wave arrival times and the timing data that P-waves have not yet arrived at other stations. REIS results play a fundamental role in the real-time information ...
A method for solving large and sparse systems with complex seismic observations has been developed by revising the classical Gaussian elimination. The observation matrix is divided into a set of smaller cells that can be determined based on clusters of seismic activity. Reliable inversion solutions with minimum error rating are selected within each cell; solutions that are unstable with respect...
