Digital signal processing has become an integral part of observational seismology. Seismic waveforms and the parameters commonly extracted from them are strongly influenced by the effects of numerous filters, both within the earth and within the recording system. With the advent of numerous software tools for the processing of digital seismograms, seismologists have unprecedented power in extracting information from seismic records. These tools are often based on sophisticated theoretical aspects of digital signal processing which, to be used properly, need to be understood. This book is aimed at observational seismologists and students in geophysics trying to obtain a basic understanding of those aspects of digital signal processing that are relevant to the interpretation of seismograms. It covers the basic theory of linear systems, the design and analysis of simple digital filters, the effect of sampling and A/D conversion, the calculation of 'true ground motion', and the effects of seismic recording systems on parameters extracted from digital seismograms. It contains numerous examples and exercises together with their solutions.

barometer readings are down to 988/990
So when is that going to turn into a storm? 980 off Iceland today.
I guess once it gets down to around the 960s it may turn into a bit of a breeze?

Unusual satellite image - have never seen line such as this. A glitch perhaps? Will check it out on Stormpulse.
BTW the house just shook for few seconds here in N. Indiana - felt like a small quake. Anything on the graphs?
