Seismic array - Wikipedia
A seismic array is a system of linked seismometers arranged in a regular geometric pattern (cross, circle, rectangular etc.) to increase sensitivity to earthquake and explosion detection. A seismic array differs from a local network of seismic stations mainly by the techniques used for data analysis. [1]
ARRAY SEISMOLOGY: METHODS AND APPLICATIONS - Rost
2002年12月5日 · Since their development in the 1960s, seismic arrays have given a new impulse to seismology. Recordings from many uniform seismometers in a well-defined, closely spaced configuration produce high-qua...
Seismic source - Wikipedia
A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite, or it can use more sophisticated technology, such as a specialized air gun. Seismic sources can provide single pulses or continuous sweeps of energy, generating ...

2002年1月1日 · In the following sections we define first the term 'seismic array' and show examples of seismic arrays installed around the world. Configuration of the regional array ARCES, which is...
Seismic Arrays - SpringerLink
A seismic array is defined as a set of seismic sensors, with the same response functions, recording time synchronized and deployed in a homogeneous area according to a certain configuration, with the aim of obtaining a coherent spatial sampling of the seismic wavefield in …
Seismometer Arrays - SpringerLink
2015年10月11日 · Seismic array data have been used to detect and investigate all kinds of small amplitude phases: seismic onsets observed in front of seismic phases, which had traversed the Earth’s core (PKP), were often interpreted as regular seismic phases, which led to many, quite controversial velocity models of the lower part of the outer core of the Earth.
Thus, in principle, a network of seismic stations can be used as an array, and data from an array can be analyzed as data from a network. The size of an array is de ned by its aperture, which is the largest horizontal distance between two sensors of the array.
Improving Microseismic P Wave Source Location With Multiple Seismic Arrays
2017年12月21日 · We demonstrate these limitations on three large seismic arrays located in Japan, Europe, and California, and find that all give a unique but imperfect insight into the P wave sources acting in the North Pacific. We then combine the data from all three arrays into one beamforming image.
Earthquake source arrays: optimal configuration and applications …
2020年1月6日 · In this paper, we presented a method to search for seismic source array elements, given a well-located earthquake swarm catalogue. The proposed method benefits from an optimization scheme, which allows to evaluate a …
Simultaneous use of multiple seismic arrays - Oxford Academic
2017年1月22日 · Simultaneous multiple array analysis provides a powerful tool for source characterization, and for structural analysis of scatterers as virtual sources. The multiple array concept allows us to illuminate a specific point in the Earth from many different directions and thus maps detailed patterns of heterogeneity in the Earth.
