AS-1 Seismograph Workshop
January 13th & 14th, 2007
California State University, Northridge – Northridge, CA
Objective(s): Teachers will be able to
· Set-up, calibrate, operate and troubleshoot their AS-1 seismograph
- Use data collected from their AS-1 seismograph as an integral part of their seismology/plate tectonics instruction
- Participate as part of a larger community of educational seismograph users.

Gerry Simila, CSUN
Outcome: Teachers will be confident that their system is
set up and working correctly, correct problems that might
arise and will know how to perform a simple calibration of
their system and to adjust the damping of their system
accordingly
Group B: Eucalyptus, Room 2304
9:45 – 10:50 Setting-up, Troubleshooting & Calibrating Your AS-1 John Lahr, USGS
Outcome: Teachers will be confident that their system is
set up and working correctly, correct problems that might
arise and will know how to perform a simple calibration of
their system and to adjust the damping of their system
accordingly
10:55 – 11:20 AmaSeis Basics John Taber, IRIS
Outcome: Teachers will be able to install Amaseis, and find
files in the AmaSeis file structure.
11:20 – 11:40 Introduction to Station Catalogs Larry Braile, Purdue U.
Outcome: The teachers will be able to keep a
station-event log
11:40 – 12:00 Where did “OUR” waves come from Lora Bleacher, IRIS
Larry Braile, Purdue U.
Outcome: Teachers will be able to import .sac files from the
AS-1 into SeismicWaves and connect the recording to Earth
Structure.
All: Eucalyptus, Room 2304
12:00 – 12:45 Lunch
Citrus (old Science 3), Room 3320
“Hurry! Come quick… WE HAVE RECORDED AN EARTHQUAKE!"
12:45 – 1:45 Recognizing Patterns In Seismograms Larry Braile, Purdue U.
1:45 – 3:15 Using AS-1 Data to Locate Earthquakes John Taber, IRIS
Outcome: Teachers will be able to apply the S minus P method to locate
Earthquakes from AS-1 data. Including; recognition of P and S
arrivals, use of the AmaSeis travel time tool to determine the S minus
P time, epicenter location on a globe, uploading and downloading
seismograms to SPINET, validating location the against USGS catalog
and verifying the epicenter-to-station distances from latitudes and longitudes.
3:15 – 3:30 Afternoon Break
3:30 – 4:30 Practice locating Earthquakes Larry Braile, Purdue U.
4:30 – 5:00 Displaying Your Data on the Web John Lahr, USGS
Outcome: Teachers will be able to install and set-up
SnagIt to display their data on the web.
5:15 Vans
Depart for Hotel
6:15 – 7:15 Dinner at hotel – details tba
7:30 – 8:15 Evening Talk: Califronia's Faults and Quakes Gerry Simila, CSUN
January 14th, 2007: Citrus (old Science 3) room 3320
7:30 Meet Vans At Hotel Lobby For Shuttle to CSUN
8:00 – 9:30 Calculate the Magnitude of An Event w/ AS-1 Data Larry Braile, Purdue U.
Outcome: Teachers will be able to determine the magnitude of an event
using AS-1 data and differentiate between magnitude estimates
(mb, MS, mbLg). Including how to measure amplitude and period of
seismic phases used in magnitude determination, how to use the
Magnitude. Calculator and how to find magnitude data in online catalogs.
9:30 – 9:45 Morning Break
9:45 -10:30 Practice calculating magnitude for events Larry Braile, Purdue U.
10:30 – 11:30 Developing an Implementation Plan Lora Bleacher, IRIS
Sheryl Braile, Happy Hollow ES
Outcome: Teachers will develop a plan to incorporate their AS-1 and
it’s data as a meaningful part of their classroom instruction in the
following year.
