Site amplification, attenuation, and scattering from noise correlation amplitudes across a dense array in Long Beach, CA
For accurate seismic hazard evaluation, both the spatial and frequency-dependent variabilities in the amplitudes of earthquake ground motions are needed. While this information is rarely fully available due to the paucity of relevant seismic data, dense arrays like the 5200-geophone array in Long Beach, California provide the opportunity to study this amplitude variability. Here we show that am...
متن کاملSite Amplification Estimates in the Garigliano Valley, Central Italy, Based on Dense Array Measurements of Ambient Noise
A frequency-domain formulation of the Aki (1957, 1965) autocorrelation method has been applied to seismic noise recorded by a 100-m wide circular array deployed on soft Holocene sediments in the Garigliano river valley, where a large amplification of ground motion during earthquakes was experienced (Rovelli et al., 1988). The application of this method to ambient noise recordings demonstrates t...
متن کاملSeismic Remote Sensing of Super Typhoon Lupit (2009) with Seismological Array Observation in NE China
The p-wave double-frequency (DF) microseisms generated by super typhoon Lupit (14–26 October 2009) over the western Pacific Ocean were detected by an on-land seismological array deployed in Northeastern China. We applied a frequency-domain beamforming method to investigate their source regions. Comparing with the best-track data and satellite observations, the located source regions of the p-wa...
متن کاملProbabilistic Super Dense Coding
We explore the possibility of performing super dense coding with non-maximally entangled states as a resource. Using this we find that one can send two classical bits in a probabilistic manner by sending a qubit. We generalize our scheme to higher dimensions and show that one can communicate 2 log2 d classical bits by sending a d-dimensional quantum state with a certain probability of success. ...
متن کاملSuper phase array
For a long time, phase arrays have been used in a variety of wave transmission applications because of their simplicity and versatility. Conventionally, there is a trade-off between the compactness of a phase array and its directivity. In this paper, we demonstrate how by embedding a normal phase array within a superlens (made of negative refractive index material) we can overcome this constrai...
