We use a slightly modified WWVB-controlled wall clock (Atomix brand supplied by Chaney Instrument Company) to generate accurate one-minute marks on our recordings. We have attached a small aluminum foil reflector to the second hand. An external LED source and phototransister assembly is used to detect passage of the second hand past the even minute time. The HeliPlot detailed waveform display shows the marks as vertical blue lines. Most of the time, the wall clock is very accurate. At certain times of the day, it goes through an alignment routine with the WWVB signal. For a minute or two, it can be almost a second fast.MENUS: File: Open Plot (Use after Open and after changing channel, gain or filter menu choices) Channel 1 Channel 2 Channel 3 Channel 4 Output (Save a filtered version of the displayed channel) Close (Not really needed) Exit Filter: No Filter (U) Differentiate (For high frequency emphasis) (D) HighPass (High pass filter, of corner period entered when chosen) (H) LowPass (Low pass filter, of type and corner period currently set up)(S) BandPass (Cascade of HighPass and LowPass) (B) Long Period (Cascade of LowPass and Broadband)(L) Broadband (A special filter for extending the effective period of the pendulum)(X) Form: 6 Hours 13 Hours 25 Hours Custom (User specified hour lines) Copy: Drum (copies the heliplot image to the ClipBoard) Detail (copies the detail plot image to the ClipBoard) View: Detail Screen ON/OFF (Heliplot version only) Header (Shows file header information in a dialog box) Settings (Details on filter settings) Update Rate: No Update (Real time plotting is suspended) Normal (Real time updates are every 256 data sample intervals) Slow (Real time updates are every 768 data sample intervals) Gain: (control of display scale) 1x, 2x, 4x, 8x, 16x, 32x Filtered Gain (2X, 1X, 0.5X) SeisCal: Set Up Smoothing (Opens a dialog box for selecting filter type and corner period for each channel) Set Up Long Period Filter (Opens a dialog box for setting up long period filter for each channel) Help: About HelpLONG PERIOD FILTERING: A pendulum type sensor does not detect well frequencies below the natural period of the pendulum. 0000375722 00000 n An earthquake has one magnitude. 0000449157 00000 n 0000419280 00000 n Timer: (used only rarely during real time recording to view filtered data) 0000064783 00000 n 0000484727 00000 n 0000360106 00000 n 0000032538 00000 n ImageMagick is command-line driven.

What is the geoid, and what does it have to do with earthquake depth? We have written a Visual Basic program "WDQ_Edit.exe" for inspection and modification of the WDQ file header, as well as other useful functions, such as file splicing, merging single files into multiple channel files, rescaling file data, and downsampling files. Magnitude calculations are based on a logarithmic scale, so a ten-fold drop in amplitude decreases the magnitude by 1.If an amplitude of 20 millimetres as measured on a seismic signal corresponds to a magnitude 2 earthquake, then:10 times less (2 millimetres) corresponds to a magnitude of 1;100 times less (0.2 millimetres) corresponds to magnitude 0;1000 times less (0.02 millimetres) corresponds An earthquake cannot physically occur at a depth of 0 km or -1km (above the surface of the earth).

The time scale and date display is derived from the file header, where the start time in seconds from Midnight Jan 01, 1970 GMT is stored. It is only as accurate as the PC system clock was at the time the recording was initiated. In order that a 24 display always be available, the first line of the plot is the hour at which recording was initiated, not 00:00 GMT as seen in the LDEO plots. Elapsed time is only as accurate as the crystal on the Dataq A/D board. Our experience with several of the DI-194 and DI-154 devices is that the sample rate is about 300 parts per million fast on all of them, so that about 1.0 seconds per hour is gained. This error can be negated by modifying the header element that stores the sample period to make it shorter by 300 parts per million. If the PC system clock was in error, it can also be corrected by changing the time information in the header. 0000051178 00000 n It may crash or malfunction for several reasons. 0000324893 00000 n 0000325047 00000 n 0000499611 00000 n 0000370512 00000 n 0000435704 00000 n 0000440935 00000 n Designed to be the hub of airport services, the airport can have two planes take off and two planes land at any time; it also has two helipads.
