Rapid urbanisation, the interconnection of economies and growing dependence on technology makes modern society increasingly vulnerable to natural disasters. In case of earthquakes, the mitigation of seismic risk in urban and industrial area can be effectively accomplished by Earthquake Early Warning systems (EEWS), which performs real-time event detection and characterization, issues rapid aler...

We present a new strategy to estimate the geometry of a rupture on a finite fault in real time for earthquake early warning. We extend the work of Cua and Heaton who developed the virtual seismologist (VS) method (Cua, 2005), which is a Bayesian approach to seismic early warning using envelope attenuation relationships. This article extends the VS method to large earthquakes where fault finiten...

Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods:...

Most of existing earthquake early-warning systems are regional or on-site systems. A new concept is the integration of these approaches for the definition of alert levels and the estimation of the earthquake potential damage zone (PDZ). The key element of the method is the real-time, simultaneous measurement of initial peak displacement (Pd) and period parameter (τ c) in a 3-s window after the ...

We have implemented and tested an algorithm for onsite earthquake early warning (EEW) in California using the infrastructure of the Southern California Seismic Network (SCSN). The algorithm relies on two parameters derived from the initial 3 sec of P waveform data at a single seismic sensor: period parameter τ c and high-pass filtered displacement amplitude Pd. Previous studies have determined ...

The combined use of seismic and geodetic observations is now a common practice for finite-fault modeling and seismic source parametrization. With the advent of highrate 1Hz GPS stations the seismological community has recently begun looking at GPS data as a valid complement to the seismic-based methodologies for Earthquake Early Warning (EEW). In the standard approaches to early warning, the in...

The Himalayan mountain range has been the locus of some of the largest continental earthquakes, including the 2015 magnitude 7.8 Gorkha earthquake. Competing hypotheses suggest that Himalayan topography is sustained and plate convergence is accommodated either predominantly on the main plate boundary fault, or more broadly across multiple smaller thrust faults. Here we use geodetic measurements...

this paper examines the characteristics of the turbulent 17th and 18th centuries of japan, investigating their impacts on the japanese dramatic literature. in particular, we examine the impact of the tokugawa society on the dramatic literature of japan, according to the plays suicide of the lovers in sonezaki, and kanadehon chushingura. these two examples reveal the entrance of a typical samura...
