GAEMP – Earthquakes and Earth Deformation

July 5,6,7, 2004

Department of Geology and Geophysics

Louisiana State University

Baton Rouge, LA

DAY 1 Field Trip to the Baton Rouge Fault

9:00 Introduction to Fault types and their association with different Plate

Tectonic Margins. Case Study of a faulting continental margin: northern Gulf of

Mexico Coast - POWER POINT PRESENTATION in ROOM E207 or equivalent

Goal: to incorporate basic geological knowledge of faults through group discussion, reading maps, GPS co-ordinates and interpreting an urban landscape

10.00 Traverse Baton Rouge using LiDAR, USGS topographic maps and GPS instrument to locate fault-line scarp

Noon-1.00 Lunch in town adjacent to College Drive fault line scarp

Afternoon: Principles of reflection and refraction seismic method. Students will set up a sample seismic experiment. Students will set off small seismic charges, hit aluminum striker plates with a sledge hammer, a steel I-beam, and an accelerated ram mounted on an all-terrain vehicle. Students will lay out phones on steel sleds on the southern side of Howe-Russell Building near the loading dock.

Goal: By the next morning, the students will need to design a field experiment for detecting a fault. Each student group must bring a cleanly illustrated design of a

24-channel geophone detector and source array justified by ½ page of written text explanation.

10 points Participation in discussion

DAY 2 Field Day (weather permitting)

6.00 TA’s and instructor start loading vehicles. A truck will be used to tow trailer and seismic equipment. Another field vehicle will carry students.

8.00 (SHARP) Depart Howe-Russell Building

Goal: Discussion of experiment design and Data collection (everyone)

Lunch in the field

6.00 p.m. return to Howe-Russell Bldg.

TA’s and instructor unload vehicle

10 points - Participation in discussion and data collection –
