Earthquake 3d Enhanced Edition V355

• 191 Downloads • Abstract Reliable analysis of low-energy earthquakes (microseismic) depends on how accurately one can detect and pick the arrival times, which are strongly influenced by the noise content. The study of microseismic events becomes even more challenging when the sensors are located on the surface because of the poor signal-to-noise ratio (SNR). Consequently, efficient and robust techniques for denoising microseismic data are necessary. In this study, we propose a method based on an infinite impulse response (IIR) Wiener filter. The proposed method uses statistics based on signal observations (noisy data) and the underlying noise, both recorded by various sensors. The method presented here precludes the need for statistics or prior knowledge of the signal of interest. The second-order statistics of the noise and the noisy data are extracted from the recorded data only.

As an advantage, in deriving the filter’s impulse response, no underlying structure of noise is assumed. Therefore, our method works for various types of noise, e.g., uncorrelated, spatially correlated, temporally correlated, Gaussian and non-Gaussian noise. Hence, the proposed method can be suitable as well for microseismic data recorded in diverse seismic noise environments.

The criteria used to optimize the filter impulse response is the minimization of the mean square error. The proposed method is tested on synthetic and field data sets and found to be effective in denoising microseismic data with very low SNR ( (-~12 ) dB).

Earthquake 3D provides a fascinating look at recent seismic activity around the globe. While the program provides a great deal of information and options, it suffers from its complete lack of direction. We were initially impressed with the interface.

The controls all looked basic, but soon we discovered that the Help file didn't do more than give a description of the product, and some actions we wanted to perform were not intuitive enough. The program itself was a spinning globe with magnitudes and the traditional multiring circles indicating earthquakes. We appreciated how the control panel let us filter quakes by severity and changed the globe's look to better see the quakes. This all functioned great, but zooming in was impossible.

We learned with ease how to rotate the globe using our mouse, but could not get a closer look, even though it's the first thing the description promised. After several fruitless minutes we grew frustrated and gave up. On a more interesting note, the program did have a feature that updated the globe with the newest quakes.

But this wasn't enough to rescue this program from its unfortunate lack of direction. Earthquake 3D is a freeware program.

The program comes as a compressed file. Even though we loved most aspects of this program, its lack of direction makes it hard to recommend.
