WebEast 34th Street Heliport ( FAA LID: 6N5) is a heliport on the east side of Manhattan located on the East River Greenway, between the East River and the FDR Drive viaduct. 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). 0000332975 00000 n This directory is not intended to be relied upon as a completely accurate depiction of existing heliport conditions. 0000344557 00000 n 0000449635 00000 n 0000436766 00000 n 0000332453 00000 n 0000468311 00000 n Each right arrow key press advances the starting time of the detail plot by 150 seconds (at 5 s/s sample rate); each left arrow key press retards the starting time by 150 seconds.

REAL-TIME OPERATION: This program can be used to monitor a file while it is being recorded by the WinDaq data recorder. If such a file is opened, the program automatically assumes its real-time mode of operation, where it updates the plot whenever the recorder dumps enough new data into the file, normally at intervals of 256 samples. The heliplot is displayed in the gain and filtering that is current. The detail plot shows only the most recent data as filtered. Older data is shown in its acquired form. If one wishes to see more filtered detail, it is necessary to replot the file, and suspend further data updates by selecting "No Update". A special "bass boost" filter has been implemented in this application for overcoming this fall-off of long period response. 0000389248 00000 n Answer: MI5. 0000444137 00000 n EVENTS I use an MS-DOS batch file consisting of two lines, which reads. It looks like you're using an Ad Blocker. The program will function over sample rates per channel ranging from 2.5 to 20 samples per second. Filter coefficients are automatically set as a function of sample rate. One the useful features of this program is its ability to display filtered seismic data as the raw data is being recorded. When a file currently open for recording is selected, the heliplot is updated as often as new data is recorded to the file (every 256 data samples). The user has almost instant knowledge of a seismic event when it occurs. The ability to examine the detailed waveform plot is retained as well.
