Evidence For and Geometry of Repeated Large Magnitude Surface Ruptures Along the Central Altyn Tagh Fault


Kite Photography along the Altyn Tagh Fault (ATF)

Introduction

Here we present some photographs we made along the Altyn Tagh in the area of Seurkuli Valley (38° 46.709'N 091° 15.238' E) of a series of offset channels and other landforms that make up the moletrack here. This is part of our ongoing work on earthquake geology along the ATF.
Go to our main ATF page.

I will try to write more about our kite system, but it consists of a radio triggered Olympus 340 digital camera (or it can fly with a small film camera) lifted by a large (32 ft2 or 16ft2) Flowform kite.

We are still developing the system. You can see some very nice images of the Landers earthquake scarp at this link:

The best image

Note the vehicle, occasional people, a total station, and some 60" aerial photo targets in these pictures. The channel in the center is left laterally offset about 11 m along the Altyn Taugh Fault whose moletrack is the linear feature crossing the image from upper left to lower right.

Processing study on the best image

Here is an effort to explore the basic Adobe Photoshop processing steps one might do and their effect on the result. I am still not completely satisfied.
