A UT Dallas researcher is working with geological scientists from
two other universities to study a gargantuan sinkhole that has swallowed a huge chunk of the East Texas town of Daisetta.

Professor Carlos Aiken of the School of Natural Sciences and Mathematics was to arrive Monday at the sinkhole site to conduct detailed
measurements with the aim of assessing whether the sinkhole is growing.
Dr. Aiken is working with researchers from Louisiana State University and the University of Idaho.
The team will work with a terrestrial laser scanner combined with Global Positioning System (GPS) and
high-resolution photography to image the surface expression of the sinkhole
to accuracies of a few millimeters.
The team will also use high-resolution GPS
measurements to assess vertical and horizontal motion in a broad area around
the sinkhole.
The sinkhole, about 60 miles northeast of Houston, has grown to more than 900 feet across and 300 feet deep.
With repeated measurements, the team will be able to monitor activity
and determine the sinkhole’s possible growth rate.
