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...

[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...

Recently, progress has been made to demonstrate feasibility and benefits of including real-time GPS (rtGPS) in earthquake early warning and rapid response systems. Most concepts, however, have yet to be integrated into operational environments. The Berkeley Seismological Laboratory runs an rtGPS-based finite fault inversion scheme in real time. This system (G-larmS) detected the 2014Mw 6.0 Sout...

[1] We determined the tc and tp parameters from the K-NET strong motion records of 16 earthquakes in Japan with moment magnitude (Mw) ranging from 6.0 to 8.3. A 0.075 Hz high-pass Butterworth filter was applied for determination of tc based on our previous studies. It was found that different pole selections of the Butterworth filter lead to different uncertainty in magnitude determination. Our...

the biological parameters of sympiesis striatipes ashmead, one of the most abundant hymenopterous ectoparasitoid of phyllocnistis citrella stainton in ehime province of japan, were studied under laboratory and field conditions. the mean immature developmental time and adult longevity at different temperatures (22 to 31â°c), 50-70% rh and 12l: 12d photoperiod decreased as the temperature increas...

the disposal of nuclear wastes is one of the most controversial issues faced by authorities in japan. in this regard, a survey was conducted among 172 university students to analyze the attitude towards the sitting of a nuclear waste repository in the country. the study focused on a number of variables that influenced the perception of risks before the 2011 tohoku earthquake and tsunami. resul...

Background: Hydrogen sulfide (H2S) suicides have been frequent in Japan in recent years. This study was performed to describe the epidemiologic profile of an outbreak of H2S suicides in Japan. Methods: In September 2008, questionnaires about patients involved in H2S suicides were sent to 250 hospitals in Japan. Data collected from each patient included gender, age, clinical manifestations, date...
