Professional Career


 

Current Scientific Research

·  Paleoseismology Research

Paleoseismological studies in the central United States. The focus of this project is to identify and characterize specific features related to historic or prehistoric earthquakes near the southern terminus of the New Madrid Seismic Zone in eastern Arkansas.  The investigation is concentrate on accomplishing 3 main goals: (1) Landsat image analysis to locate areas potentially disturbed by severe ground shaking; (2) detailed aerial and land surveys to identify and locate features potentially related to historic or prehistoric earthquakes; and finally (3) to trench, log, and sample four additional sites that exhibit characteristics of seismic activity.  Recently conducted aerial and field surveys reveal the existence of liquefaction features (sand blows) and linear features as far as south of Marianna, Arkansas. This is more than 100 kilometers from the currently active segments of the New Madrid Seismic Zone.  These possible earthquake-related features are significant for the following reasons: (1) they are at considerable distance from present-day earthquake activity.  The implication of this is that they represent a new earthquake source region not previously recognized, or that they were caused by an earthquake(s) of very large magnitude in the source region of the New Madrid Seismic Zone.  (2) These features appear to have very large dimensions (some ~110 meters), resembling features in the immediate vicinity of the New Madrid Seismic Zone. The implication of this is that no matter where the source region is, the ground shaking was significantly severe in order to generate them.  (3) Potentially, detailed investigation of these features will have important implications for earthquake risk mapping in the central United States. (4) They may provide important constraints on the southern terminus of the New Madrid Seismic Zone and the magnitude of the characteristic earthquake in the region.
 

·  Terrestrial Geophysics

Research the effectiveness of the combined application of both seismic sounding and electric techniques in prospecting for subsurface water/ice on Mars.  The research is part of a multidiscipline project that includes computer engineering, robotic, and communication.  The research requires the collection of ground truth data for our analysis.  Electric measurements (resistivity/conductivity, electromagnetic) and seismic sections will be constructed for a number of well-controlled laboratory models and actual well-known earth structure.  Laboratory scaled models and the selected earth structure will simulate what is known of the Mars’s conditions.

·  Fluid Effects on Elastic Properties

Studying the effect of fluid-filled cracks and micro cracks in the upper crust on seismic velocities and attenuation of P and S waves. This project investigated the utilization of the lateral and/or three-dimensional velocity and attenuation variation, with other geophysical and geological constraints, as fluid indicators.

·  Array Data Analysis

Analysis of 3-component broadband data from small and large aperture arrays (in the U.S. and the former Soviet Union) to study near-surface station site effects on the high frequency waves recorded by these arrays. The project also investigates source characteristic and path effects on seismic waves. The project has expanded recently to include site amplification, shear wave splitting and anisotropy.

·  Potential Fields Analysis

Developing a new method of inverting gravity data to determine three-dimensional distribution of rock density to delineate deep and/or shallow earth structure. This method uses state of the art linear inversion techniques, which allow the user to handle a very large number of observations and unknown parameters.

·  Shallow Geophysics

Use of various geophysical methods (Ground Penetrating Radar, seismic, electric, gravity, and magnetic) to locate and map shallow subsurface structure. This project was initially developed to study the effectiveness of these methods to study soil liquefaction and site characterization in the New Madrid Seismic Zone and the Wabash Valley Seismic Zone. The work was in support of the National Earthquake Hazard Reduction Program to study the seismic risk in the Central United States.

Improve the technologies and develop new software to use Ground Penetrating Radar equipment (both short pulse and step frequency) and to interpret their data. Part of this research is to study the signature of different type of materials on the recorded radar waves. Both natural and man-made materials are used to study attenuation, reflection, and refraction of radar waves.

·  Automatic Signal Detection

Developing new techniques, such as the F-detector, the Lag-closure detector, and data covariance matrix, for automatic detection of seismic and infrasonic signal using multi- and single-channel processors. The new procedures are being tested for its capability of accurately determines the onset time of seismic and acoustic waves. This includes the use of the derivative of the F-statistic function of array data. This research is being conducted to support the United States Air Force to monitor a Comprehensive Nuclear Test Ban Treaty (CTBT).

·  DRWP Analysis

Develop a software package to automatically process and interpret Doppler Radar Wind Profiler data. This program is currently supported by NASA to improve its capabilities of producing real-time wind velocity profiles using frequency-domain Doppler shift data from different hardware systems. In addition to detecting severe weather and shear layers, NASA uses these profiles for the Shuttle and other space vehicles safety.

·  Hazard Mitigation

Development of the State of Arkansas Hazard Mitigation Plan. This project is currently supported by the Arkansas Department of Emergency Management to develop a working plan to mitigate natural and man-made hazards. The plan and its data, maps, figures, and results are currently produced in GIS ArcView format. A similar high-resolution plan is presently developed for Clay County, AR. This project is also supported by the Arkansas Department of Emergency Management to help the county's activities as being one of FEMA's Project Impact communities
 

Public Education

As a director for the Center For Earthquake Studies (ACEETT), University of Arkansas at Little Rock (UALR), I have the responsibility of supervising the process of educating the public about the risk and mitigation of natural phenomena such as earthquakes and flooding. The education is in the form of seminars, short courses, general lectures, public displays, publication and distribution of general educational materials, and development of Internet Websites. The ACCEETT staff and activities are supported by grants from the Federal Emergency Management Agency (FEMA), the State of Arkansas Department of Emergency Management (ADEM), and University of Arkansas at Little Rock (UALR). To increase public education, I have conducted several radio and television talk shows and interviews and published several newspaper articles.

Field Trips:

Most of the field trips are part of the student’s activities to fulfill part of the requirements to Applied Geophysics course. This course is designed to introduce the field techniques employed by geophysicists to explore the Earth’s interior. Students first learn the theory behind the basic principals of the Earth’s behavior in a series of lectures. The concepts of gravitational and magnetic force are discussed and the students are encouraged to piece together reasons for alterations in the Earth’s gravity and magnetic fields. The effects of shallow crustal features are also thoroughly explored.

Field Experiments

Gravity Studies- To measure variables in the Earth’s gravity field, students survey the lamproite intrusion at the Crater of Diamonds State Park near Murfreesboro, Arkansas. A Worden gravimeter is employed to determine the gravity anomalies across the intrusion and the surrounding native sedimentary rocks. Positive gravity anomalies, attractions higher than the theoretical values expected for the area, correlated well with the high-density rocks of the lamproite pipe. Models of the intrusion are constructed using the reduced data from the field readings. The resulting configuration shows a narrow intrusive pipe that widens abruptly as it reaches the surface. The structure of the pipe loosely resembles a stemmed wine glass.


 

Magnetic Studies- When electrons spin randomly the net result is that their magnetic fields cancel each other and the substance containing them does not display magnetic properties. However, when magnetic substances are subjected to a strong external magnetic field the electrons tend to spin in one direction. In this circumstance their internal fields become aligned and a strong, permanent, magnetic field is created. Different compounds have variable capacities for storing the magnetic field. Mafic rocks like those found at the Crater of Diamonds State Park near Murfreesboro, Arkansas contain small amounts of iron and magnesia which are weakly magnetic. Rocks such as magnetite and jacupirangite contain large amounts of iron and become strongly magnetic when exposed to external magnetic fields. The ring dyke intrusion at Magnet Cove, Arkansas has strongly magnetic signal. These two areas are surveyed by students using a Bison proton precision magnetometer. A model is constructed of the resulting magnetic anomalies. In both surveys a strong correlation is associated with the iron bearing rocks of the magmatic intrusions.


 

2-D Seismic Profiling-The students conduct this field study to determine the shallow subsurface structure of the UALR campus. A seismic profile is constructed using a series of 28 Hz geophones. A seismic signal is then generated using a strike plate and sledgehammer. A two layer over half layer model is suggested by the seismic data from this site. The first layer is indicative of a combination of a fill layer remnant from a time of construction and alluvium type materials. The eastern end of the profile clearly shows an abandoned stream channel. This is interpreted to represent an old flow path of Coleman Creek. The second layer is characteristic of a partially weathered bedrock surface. The half layer has a much high velocity and is representative of a non-weathered bedrock layer.


 

Ground Penetrating Radar (GPR) Profiling- Students conduct GPR studies using both a 900 MHz and 400 MHz antennas. The 900 MHz antennas provide excellent resolution of objects at shallow depths, 50 cm. This model is ideal for concrete and structural evaluations. For this portion of the survey the floor of room 101, The Arkansas Center for Earthquake Education and Technologies Transfer, was partitioned into three transects. The floor, which was concrete over compressed fill construction, contains rebar at a depth of 4-5 cm. One set of rebar is oriented in the east-west direction and a second set is oriented in the north-south direction. This rebar intersects at a 90° angle. When a traverse is taken at a 45° to the intersection points both layers of rebar maybe visualized in the same image.

The 400 MHz antennas provide visualization to a depth of up to 5 m under ideal conditions. For this reason an outdoor site is usually best for 400 MHz survey. The upper 3 m of geologic features as well as tree roots, zones of soil disruption, and buried utilities are easily identified along the transect that runs from the edge of faculty parking lot 1 to Campus Drive on the UALR campus.

The coarse is designed to accommodate students at both the undergraduate and graduate level. The wide variety of field experiences and large degree of student participation provides an excellent learning environment.
