Pressure Wave and CO2 Seismic Events Description

This applet is a profile viewer in time that will display the pressure wave data and the selected CO₂ seismic sensor wave data for a specific seismic event (earthquake). The user selects a seismic event they wish to view and the program automatically retrieves from the Kansas Geological Survey (KGS) Server the Pressure Comma Separated Values (CSV) file and the Seismic Sensor miniSeed file that corresponds to the time of the seismic event and displays in the profile plot. The user is allowed to perform simple filtering on both data sets and to display a Frequency vs. Magnitude plot of each of the data sets.

The pressure measurements started at 25 April 2016 at 13:49, each data step is at 1 second interval. Each miniSeed file is in 1 hour time interval. All data files are stored on the KGS Server. The miniSeed files for one day contained up to 7 seismic sensors with 3 channels at one hour intervals, i.e. 504 miniSeed files per day.

This applet will download the CO₂ Seismic Events from the KGS ORACLE Database as Extensible Markup Language (XML) data stream. This data is accessed using an ORACLE PL/SQL Stored Procedure http://chasm.kgs.ku.edu/ords/iqstrat.co2_events_pkg.getXML

You can also download a "CSV" output from the ORACLE Database, which can be saved as a Comma Separated Values (CSV) File to your PC, with the following link, http://chasm.kgs.ku.edu/ords/iqstrat.co2_events_summary_pkg.build_csv_all_page

The Pressure sensor is set at the Arbuckle Formation in the Wellington KGS 1-28 (15-191-22590) Well, listed below,

Note: Each miniSeed file holds data for a specific Channel (orientation) for one hour. There are 3 channels for each hour, which are described as follows,

Seismic Sensor Channels

Channel Orientation
EHZ Z - Vertical

EHN N - North-South

ENE E - East-West

E - Extremely Short Period { >80 to < 250 Hz }

H - High Gain Seismometer
