The Academic Program

The Department of Geology and Geophysics (GG) is centered around the scientific study of the exterior and interior of the Earth and other planetary bodies. Sub-disciplines within GG are many, and offer rich opportunities for multidisciplinary study of problems of great intellectual and practical importance. Coastal geologists study processes such as sedimentation and beach erosion, reef growth and degradation, and sea level change. Hydrologists and Hydrogeochemists study the cycling of fresh water between the atmosphere, land, and ocean. Of particular emphasis is how climate change impacts this cycle; how fresh water supplies are impacted by human activities, including land-use practices and the introduction of contaminants into surface and groundwater; how climate, hydrologic, and terrestrial processes impact the ocean and its ecosystems by way of surface water and submarine groundwater discharge. Structural geologists study the physical features in rock units with respect to stress and deformation related to processes such as mountain building, rifting, and earthquakes. Engineering geologists provide geotechnical recommendations affecting the design, construction, and operation of engineering activities, based on geologic factors such as material properties, landslides and slope stability, erosion, and flooding. Mineralogists and petrologists examine the temperature, pressure, and environmental conditions that influence the formation of minerals and rocks. Geochemists specialize in the chemistry of earth materials for gaining knowledge about a huge range of aspects including the make-up of the deep earth, the formation of the seafloor, the origin of volcanoes, as well as past and present changes in Earth's climate, ocean environment, and life. Volcanologists study how gas, fluid, and magma interact to create different types of volcanic eruptions, and address hazard remediation. Geophysicists use seismology, potential fields, sonar, radar, and GPS for studying earthquakes, Earth's surface and internal structure, land deformation, and plate tectonics. They also use mathematics, continuum mechanics, and high performance computing for studying Earth and planetary processes. Planetary scientists examine how the Earth and Solar System formed, study active processes on planetary bodies, search for extrasolar planets, and explore planetary conditions needed for life.

Undergraduate and graduate students in GG are instructed and advised by world-class researchers in a variety of the above sub-disciplines. Students participate in a diverse course curriculum involving in-class instruction, laboratory activities, and field trips. They have access to state-of-the-art facilities including a number of different types of mass spectrometers, an electron microprobe, an X-ray fluorescence laboratory, and high-performance computing facilities. Field trips take students to volcanoes on Hawai'i and other islands, as well as geologic settings on the U.S. mainland and around the world. Students also participate on research cruises onboard one of several research vessels that are operated by SOEST. GG students who are involved in research projects regularly present their findings in scientific conferences and journal publications. These varied activities allow students to take full advantage of Hawaii's unique geographic location and its rich geologic and environmental setting.

Students graduate from the Department of Geology and Geophysics (GG) with an in-depth understanding of the relevance of the geosciences to society, especially Hawai'i and Pacific islands, as well as the ways human civilization impacts the Earth and environment. Students are able to use basic skills in math, physics, chemistry, and biology as well as technical knowledge in computer applications, laboratory methods, and field techniques for solving real-work problems in the geosciences. Graduates know how to ethically apply the scientific method, and can use basic principles in geoscience for explaining natural phenomenon. GG graduates develop proficiency in communicating their knowledge in oral presentations and in writing professional documents. As a result, GG majors are widely successful in obtaining jobs in fields within or closely related to the geosciences. These fields include environmental assessment and remediation; engineering; geotechnical consulting; oil, natural gas and mineral resources; water resource management; science education; as well as applied and basic research.


Students contemplating a major or minor in geology and geophysics should contact the Director of Student Services for SOEST in HIG 135 (tel. 956-8763). There are two undergraduate advisors who may be contacted through the department office (956-7640, ggdept@soest.hawaii.edu). Graduate students are appointed a faculty advisor upon admittance into the program.

Undergraduate Study

BA in Geology


The BA degree in geology is appropriate for students interested in Earth science but not necessarily intending to pursue graduate work or employment in traditional geological sciences. It is more flexible than the BS program and is suitable for students who are considering a double major or teaching.

The BA degree requires completion of 120 credit hours of coursework, the equivalent of four years of full-time study. The BA program requires 35 credits in the geology and geophysics curriculum. This includes one introductory level GG course with a lab, seven non-introductory GG courses, a two-credit research seminar, and at least five credits of approved upper division electives. With the advice and consent of an undergraduate advisor, courses in other natural sciences, mathematics, or engineering may be substituted as electives. A mainland summer field course is an elective that students are strongly encouraged to take. Required support classes include physics, chemistry, biological sciences, and one semester of college calculus; these total 23-24 credits and should be taken as early as possible. A minimum grade of C (not C-) must be achieved in all major and support classes.

Graduate Study

Admission Requirements

All applicants must take the GRE General Test. All students are urged to have completed a course in a computer programming language before entrance. U.S. applications are due by January 15 for admission in the fall semester or by September 1 for the spring semester. International applications are due January 1 and August 15, respectively.

Undergraduate deficiencies will be determined from the student's transcripts and intended field of study. Undergraduate course work deficiencies will be assessed at the preliminary conference. GG 611 is intended for students entering from a non-geoscience field to prepare them for graduate studies in the geosciences.

Masters in Geoscience for Professionals (MGeo)

The MGeo is a professional degree for individuals seeking advanced training for careers in geoscience-related industries or federal, state, and local agencies. Key courses are appropriately scheduled or administered for working professionals to obtain an MGeo in as little as two years of half-time study. Applicants must have a bachelor's degree in the natural sciences, mathematics, or engineering, and are normally expected to have completed at least one year each of college mathematics, geology, physics, and chemistry.


The MGeo degree requires a minimum of 30 credit hours, including a total of 6 credits of MGeo Professional Project. At least 12 credits will be in GG graduate courses (GG 600-740), excluding GG 699; and 12 credits may be taken from a list of upper-division undergraduate courses that emphasize applied geoscience.

MGeo Seminar is a 1-credit course that must be taken each year, up to three times. Students will participate in a professional work project as an employee, intern, or volunteer with a company or agency (gaining the credits in MGeo Professional Project), and present the outcome of the project in final oral presentation as well as a written report.

Master's Degree

Intended candidates will be accepted from undergraduate majors in the natural sciences, mathematics, and engineering, and they normally would be expected to have completed at least one year each of college mathematics, geology, physics, and chemistry. Adequacy of each applicant's additional preparation will depend on the particular branch of geology and geophysics being pursued. At the time of application the student should state the field in which he or she intends to study.


For MS students, the graduate studies committee of the department will determine suitability of Plan A (thesis) or Plan B (non-thesis) at the preliminary conference. Virtually all students are required to follow Plan A. Plan A requires a minimum of 30 credits, including 6 credits of GG 700 Thesis Research and at least 24 credits of course work (up to 6 course work credits may be in GG 699). Plan B requires a minimum of 30 credit hours of course work and a final exam.

Doctoral Degree


PhD candidates are accepted with either a BS or MS degree. Students without an MS must pass a qualifying examination given at the beginning of their second semester in residence. All PhD candidates must pass a comprehensive examination no later than at the end of the fourth semester of residence for students without an MS degree or at the end of the second semester of residence for students with an MS degree. The comprehensive exam includes oral and written parts that cover in-depth subjects in the student's field of interest and also relevant general information from this and other departments. A final examination in defense of the dissertation is required. Space and financial aid for the program are limited, so each student's progress will be reviewed annually.

Areas of Interest

The areas of interest listed below are active fields of research in the department. For each, a brief description and the required undergraduate preparation are listed. Students with backgrounds other than these may be accepted in a field if their records and recommendations are strong, but advancement to candidacy may be delayed. A complete statement of the courses and other work in each field necessary for the MS or to prepare for the PhD comprehensive examination will be given to the entering student.

The department can provide further information on research opportunities and financial aid in each of the areas of interest.

Geophysics and Tectonics. Studies in geophysics and tectonics at UH Manoa are interdisciplinary and include experimental and theoretical developments, field-based observations, and computer simulations. Together, they provide students with a background that combines both geology and geophysics for technical and professional work at industrial, governmental, and academic institutions. Subtopics include: (a) Plate Tectonics-rift propagation and plate break-up; initiation and evolution of continental margins and back-arc basins; relative and absolute motion of plates; thermo-mechanical properties of oceanic lithosphere; mantle convection and the driving forces of plate tectonics; and hot spot and intraplate volcanism; (b) Seismology-theory and analysis of seismic waves from active and passive sources; ocean-bottom geophysical instrumentation; multichannel seismic imaging of subduction zones, accretionary prisms, and submarine volcano flanks; (c) Geophysical Fluid Dynamics-mantle flow and plume-plate interaction; plate generation and rheology from mantle flow; ocean/shore dynamics and nonlinear waves; (d) Rock Fracture Mechanics-field, theoretical, and laboratory analyses of the mechanics of fault growth, rock fracture, dike propagation, landslides, and crustal deformation; these topics are relevant to plate tectonics, structural geology, and engineering geology.

Entrance may be through majors in geophysics, geology, mathematics, physics, or engineering. Students need a background in geology (which can be obtained in graduate school) together with supporting mathematics and physics.

Marine and Environmental Geology. The Marine and Environmental Geology (MEG). The Marine and Environmental Geology program is focused on the dynamic physical, biological, and chemical interactions that characterize Earth surface terrestrial and marine environments and also the history of these interactions over the course of geologic time. Researchers work on problems ranging from those of pure scientific curiosity of global phenomena to pragmatic problem-solving of environmental problems, and including everything in-between. Faculty and students of the MEG group travel to field sites all over the world to study processes and interactions between water, atmosphere, sediments, and living tissues, and their travel also includes several large-scale projects located within the Hawaiian Islands. Research also extends backward through deep time, integrating the biological and physical aspects of earth history through the study of rocks and fossils. Instruction is designed to provide students with hands-on exposure to the most exciting, contemporary issues in environmental science, particularly on topics where the fields of geology and oceanography overlap with other environmental sciences. Laboratories use the newest biogeochemical technologies and instrumentation in order to assess the health and integrity of coastal systems, to reconstruct past climates and life forms, to characterize the movement of precious water resources, and to understand the chemical cycling of both organic and inorganic components of the ocean. MEG research topics carry important implications and benefits for the sustainability of fresh water resources and reserves, agriculture, coastal and marine ecosystems, fisheries, Hawai'i's beaches and economy, and other topics of immediate societal concern.

Many research efforts in this program involve participation in oceanographic expeditions. Graduate students are encouraged to participate in these voyages as a part of their career training. The program is multidisciplinary with cooperating faculty and courses from several other departments including civil engineering, geography, oceanography, and soil sciences. The diverse research and teaching interests of the faculty make it possible to tailor graduate degree work to fit the needs and desires of the student. Requirements for admission typically include an undergraduate major in geology or one of the other natural sciences, along with basic courses in physics, chemistry, and mathematics. Students often study a combination of geology, geophysics, oceanography, biology, civil engineering, and/or geochemistry, as appropriate for his or her optimum intellectual development.

Volcanology, Geochemistry, and Petrology. UH Manoa is uniquely situated to study all major aspects of volcanic systems. Active Hawaiian volcanoes are natural laboratories of intraplate volcanism and hydrothermal activity; eroded fossil volcanic systems on other islands provide windows into deeper volcanic structures; and Hawai'i is at the center of the Pacific "Ring of Fire." Collectively, the VGP group has active field programs that are global in scope. The group studies submarine volcanoes with UH Manoa and other research vessels, and on terrestrial volcanoes around the world, and participates in remote monitoring of volcanoes on Earth and other planets using ground-based and space-borne observatories. Faculty of the VGP group operate a wide range of modern, well-equipped, state-of-the-art analytical laboratories that provide data on the chemical composition and physical properties of rocks and minerals. In addition, VGP covers basic courses in Hawaiian geology, geologic hazards, geochemistry, optical mineralogy, petrology, structural geology, volcanology, geological field methods, remote sensing and GIS techniques.

Specialized topics that members of the group study include (a) geometry and dynamics of mantle flow, melt generation and magma chamber processes at submarine volcanoes from petrologic, geochemical, and isotopic variations at mid-ocean ridges and back-arc basin spreading centers; active volcanism at submarine volcanoes; geochronology of submarine volcanism, and volcano interactions with the submarine environment; (b) physical processes at volcanoes giving rise to degassing, and fragmentation of magma in conduits; transport and deposition from volcanic plumes and pyroclastic density currents; flood basalts and the eruption and emplacement of lavas; caldera volcanoes and ignimbrites; volatile degassing and retention in magma chambers; environmental impact and social consequences of eruptions; and volcanic processes on extraterrestrial bodies. (c) geochemical and isotopic tracing of mantle composition and evolution; geochemical cycling; geosphere-hydrosphere exchanges; (d) petrologic, geochemical, isotopic, and geologic evolution of Hawaiian and other oceanic islands and seamounts; petrologic, seismic, and geodetic monitoring of magmatic systems at active Hawaiian volcanoes; satellite monitoring of volcanic hazards and eruption clouds; remote-sensing observation of extraterrestrial volcanoes.

Entrance through majors in geology or chemistry is most typical. Students need a background in geology (which can be obtained in graduate school) together with supporting mathematics and physics.

Planetary Geoscience and Remote Sensing. This program, centered in the Hawaiian Institute of Geophysics and Planetology (HIGP), studies the geology and composition of objects (planets, asteroids, moons, and meteorites) in the Solar System to understand their origin and evolution. It involves research in planetary and terrestrial geology, cosmochemistry, volcanology, planetary astronomy, and scientific instrumentation. Current research areas include: (a) research on extraterrestrial materials from asteroids, the Moon, and Mars as records of processes in the solar nebula; alteration processes; the effects of shock; igneous processes; and planetary crustal compositions and evolution; (b) remote sensing and petrology of the moon, Mars, and Mercury to understand planetary formation, differentiation, and weathering of planetary crusts, volcanic processes, and the mode of formation of impact craters. Faculty are science team members on multiple planetary missions (MESSENGER, Lunar Reconnaissance Orbiter, Mars Odyssey, and Mars Reconnaissance Orbiter); (c) terrestrial remote sensing using spacecraft (Landsat 7, EO-1, Terra, Aqua, GOES), aircraft, and ground observations to study the flux of magma through volcanic systems, eruption precursors, forest fires worldwide and the like. Data from the GOES geostationary satellite are made available on the HIGP website (goes.higp.hawaii.edu) and MODIS thermal alerts for the entire world are made available at modis.higp.hawaii.edu. Imaging radar remote sensing is also conducted within HIGP. This includes interferometric studies of volcano deformation using ENVISAT and ALOS data for understanding magma emplacement and volcano tectonics. HIGP is a major partner (with the College of Engineering) in the Hawai'i Space Flight Laboratory, which includes preparation for future UH-led space missions involving small satellites; (d) developing instruments for use in studying global and regional problems in Earth and planetary science, such as hyperspectral thermal infrared imagers for use in lithologic mapping, the analysis of temperature anomalies, the flux of sulfur dioxide from volcanoes, an infrasonics array for a global monitoring system for the detection of atmospheric disturbances, and lidar systems for the measurement of atmospheric aerosols and rock compositions.

Typically, an undergraduate major in geology, astronomy, physics, or engineering, along with basic courses in chemistry, physics, and mathematics, would be sufficient for entrance. The student should be prepared to commence or continue course work in whatever combination of geology, geophysics, geochemistry, planetary science, spectroscopy, radar science, or remote sensing is appropriate for optimum development in the field and to satisfy minimum requirements in the Geology and Geophysics department.
