UNIVERSITY OF PAPUA NEW GUINEA Courses in the Division of Geosciences center on geology, the study of the earth. Geologists investigate the origin of the earth and planets, the earth’s evolution, and the processes that shape the earth. The earth formed about five billion years ago, and our planet's history since then has been dominated by two driving mechanisms. Internal heat from radioactive decay melts rocks, causes volcanoes, and builds mountains. External heat from the sun drives the atmosphere and oceans, destroys rocks through weathering, and creates sediment. Mountain building and most volcanoes are caused by the movement of large plates that form the outer shell of the Earth, and whose motions are driven by the earth's heat. The plates are about one hundred kilometres thick and "float" on a layer of plastic-like material, which deforms like modelling clay. Geologists study the earth both as an intellectual challenge to understand the processes that form and shape our environment and as a tool to improve life. Geologists have discovered the great antiquity of the earth, have demonstrated biological evolution and the origins of the human species through the fossil record, and have documented the waxing and waning of great ice sheets. Thick glaciers, similar to those now in Antarctica, covered much of the continents as recently as 20,000 years ago. Geologists have shown that the earth is dynamic and continually changing. Geologists also have determined that large meteorites have collided with the earth on occasion. A meteorite impact is argued by some to have caused the extinction of many dinosaur species.

Geo-Hazard Index Technology Page Geology Home Erosional Landforms WWU Network Path The Hydrologic System The hydrologic system, which includes all possible paths of motion of Earth's near-surface fluids including air and water, is largely responsible for the variety of landforms found on the continents. Heat from the sun evaporates water from oceans, lakes, and streams. Although most of the water returns directly as precipitation to the oceans, some of the water is precipitated over land as rain or snow. If it is precipitated over land, it then begins its journey back to the sea as "runoff." The relentless action of surface runoff, streams and rivers, glaciers, and waves sculpts the rock into intriguing and bizarre shapes. Water Erosion of Horizontal Strata in Semiarid Lands After the horizontal strata in today's semiarid landscapes were deposited, they were uplifted, twisted and cracked, forming joints-parallel fractures in the brittle rock. These joint systems are made vulnerable to weathering and frost wedging by the erosion of the overlying resistant layers. As the joints and fractures widen, rock fins are produced. In addition to fins, large flat areas called plateaus may be eroded along joints into smaller flat topped mesas and still smaller buttes. Buttes are further eroded into pillars and pinnacles. Slabs of rock may break away between two joints in a fin so that an alcove (a recess) forms. As the alcove enlarges, a small window may be produced in the cliff face. Weathering then proceeds inward from all surfaces, and as weathering removes the rock surface, pressures locked within the formation itself are released, breaking off more rock flakes. Rock falls from the ceiling of the opening, and the span thins and elongates. These erosive forces-dissolution, frost action, and release of compression-eventually enlarge the window in the fin, and creates an arch. Variability in the cementing materials and the rock structure in the arch floor, buttresses or ceiling determines the size, shape, and age of the arch. The shape and size of the arches changes over time, and the forces that created an arch finally destroy it leaving goblin-like columns.

Geo-Hazard Index Technology Page Geology Home Eruption of Mt. St. Helens, 5/18/1980 WWU Network Path THE ERUPTION OF MOUNT SAINT HELENS, MAY 18, 1980 The May 18, 1980, eruption of Mount Saint Helens was the most destructive in the history of the United States. Mount Saint Helens is located in southwest Washington in the Cascade Range, a mountain range dominated by periodically active volcanic peaks (see map). Geologists and volcanologists had been studying Mount Saint Helens in the 1970s and had predicted an eruption before the end of the century. The mountain had been recognized as a dormant volcano that had erupted intermittently from 1831 to 1857. The Klickitat Indians of the Pacific Northwest called Mount Saint Helens "Louwala-Clough" or smoking mountain. However, the beautiful snow-covered peak looked serene to the casual observer just days before the start of eruptive activity. On March 20, 1980, seismographs in Washington and Oregon began recording earthquakes and a rhythmic ground shaking known as harmonic tremor (an indicator of the subsurface motion of gases or magma). A series of phreatic (steam) eruptions began on March 27. Shortly after the start of eruptive activity geologists noticed another sinister indicator of impending disaster. The north flank of the mountain had begun to swell. Aerial photographs indicated that the "bulge" increased the height of some areas of the north side of the mountain by more than 450 feet. On May 18th the bulge collapsed, triggering the eruption.

33. TSUNAMIS tsunamis can be generated quotby any largescale, short-duration disturbance of earthmovement, subsidence, or volcanic eruption (Glossary of geology, 1980). http://www.johnmartin.com/earthquakes/eqpapers/00000051.htm

from California Geology, March 1981, Vol. 34, No. 3. TSUNAMIS By DIANE PIERZINSKI Environmental Planner Department of Conservation INTRODUCTION The earliest efforts to explain great sea waves were made in legend and story by people who lived on land that bordered the ocean. Early Greek philosophers tried to explain the huge sea waves in various ways. The Greek historian Thucydides (fifth century B. C.) attributed the waves to earthquake forces. Aristotle believed the "air element" of Greek cosmology caused earthquakes which created the huge waves. Strabo, who contributed one of the last Greek explanations, came closest to modern theory when he wrote: "For the floor [of the sea] that is saturated with water is far more easily moved and is liable to undergo more sudden changes. . . . Deluges, as we have seen, are caused by upheavals of the bed of the sea; and earthquakes, volcanic eruptions, and upheavals of the submarine floor raises the sea, whereas the settling of the sea lowers the sea . . ." (Ambraseys, 1962). At this point inquiry stopped. The origin of the great sea waves was considered again in the late Renaissance period and has been of interest and concern to scientists to the present day.

Natural hazards such as storms, hurricanes, and tsunamis are driving forces in coastal processes and landforms. When combined with increasing sea levels, these events may have tremendous impacts on our coastal environments and beaches. Coastal communities must be aware of natural hazards and take steps to prevent the loss of life and property caused by these events. Pre- and post-storm management plans must be developed and used to ensure the safety and protection of coastal populations and natural resources. Storms provide much of the sediment to fragile, shallow marine and estuarine ecosystems. Many wetland environments depend on storm activities for sediment build-up and survival when faced with rising sea levels. Select a hazard from the choices to the left. Rip Currents Rip currents are strong and swift, moving 1 to 2 meters per second, which is faster that an average person can swim! These currents are created due to set-up near the shoreline. Set-up is a slight (~ cm) increase in water levels compared to those found seaward of the surf zone. Set-up creates unstable conditions that are eventually relieved through the formation of rip currents. These dangerous currents generally form at a low point or saddle in a sandbar. Because rip currents tend to be narrow, swimmers caught in a rip current should swim parallel to the shore to escape being taken out to sea. Swimmers should be especially cautious during storm events, which may increase the frequency and strength of rip currents.

IMPACT GEOLOGY, CHEMISTRY AND PHYSICS Contents Introduction The Physics of Impacts The Chemistry of Impacts The Geology of Impacts ... Some Interesting Websites Introduction When the Shoemaker-Levy 9 comet hit the planet Jupiter in 1994 the heat released could be detected by astronomers on Earth. It is thought that throughout Earth's history, there have been similar impacts by various comets and asteroids . The best documented case of recent years occured in 1908, when the Tunguska comet exploded just prior to an impact in Siberia, causing destruction over an area approximately 30km in diameter. In photographs of the moon it is often quite easy to pick out the circular depressions which are thought to be a result of impacts. On Earth, such craters are more difficult to identify due to the effects of erosion and weathering, cover by vegetation or younger rocks and the destructive effect of plate tectonics . However, impact craters can be identified by consideration of not only their shape, but also by unique geological, chemical and physical characteristics. To date, approximately 150 impact structures have been identified on Earth's surface. These have often been identified using
