Seismology Instruction with the AS 1

Storing Event Information

     Once you have identifi ed an event that your AS 1 has recorded, you can store information 

about it for future instructional use.  There are many applications for using real time seismic 

data in the classroom.

     To store data about an event: 

   On the Extract Event Screen select Settings > Event

   Enter the event 

information in the Event 

 Dialog box.

   The Seismogram Start 

time will be pre fi lled and 

            should not be changed.

   Earthquake Origin Time

 AmaSeis 

will 

pre fi ll part of 

this section, use information 

from an NEIC or IRIS 

bulletin to input the event 

parameters of latitude, 

longitude, origin time, and 

 depth. 

NOTE:  Using internet earthquake databases is described in the next section.  Use these 

databases to gather the above information about the event.

   The latitude and longitude must be entered as signed 

numbers, negative for west longitude and negative for 

 south 

latitude. 

Magnitudes

Record any magnitude reported by IRIS, NEIC, or if you calculated your own station 

magnitude report it here.

NOTE:  Data from the AS 1 can be exported for use in Seismic Waves.  See the SpiNet 

website for additional documentation on this feature.
