United States Search and Rescue Task Force Earthquakes One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible after effects. An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate tectonics have shaped the Earth as the huge plates that form the Earth's surface slowly move over, under, and past each other. Sometimes the movement is gradual. At other times, the plates are locked together, unable to release the accumulating energy. When the accumulated energy grows strong enough, the plates break free. If the earthquake occurs in a populated area, it may cause many deaths and injuries and extensive property damage. Today we are challenging the assumption that earthquakes must present an uncontrollable and unpredictable hazard to life and property. Scientists have begun to estimate the locations and likelihood's of future damaging earthquakes. Sites of greatest hazard are being identified, and definite progress is being made in designing structures that will withstand the effects of earthquakes. The scientific study of earthquakes is comparatively new. Until the 18th century, few factual descriptions of earthquakes were recorded, and the natural cause of earthquakes was little understood. Those who did look for natural causes often reached conclusions that seem fanciful today; one popular theory was that earthquakes were caused by air rushing out of caverns deep in the Earth's interior.

25. Earthquakes earthquakes. Vibrations of the Earth caused by the sudden release of energy, usually as a result of displacement of rock along faults. http://www.geo.ua.edu/intro03/quakes.html

Earthquakes Vibrations of the Earth caused by the sudden release of energy, usually as a result of displacement of rock along faults. An earthquake is always followed by a series of smaller earthquakes (aftershocks) which represent further adjustments of rock along the fault. Approximately 13 million people have died as the result of earthquakes during the past 4,000 years. There are currently no reliable methods for predicting when earthquakes will occur. Cause of Earthquakes Earthquakes are caused by the sudden release of energy along faults. Elastic-Rebound Hypothesis - The idea that strain builds up in rock until the elastic limit (strength) of the rock is exceeded. The rock then ruptures (fails) at a point, snapping back toward an unstrained position. releasing the elastic energy as seismic waves radiating outward from the break. The greater the stored strain, the greater the release of energy. Seismic and Volcanic Activity - The coincidence of many active volcanic belts with major belts of earthquake activity indicates that volcanoes and earthquakes may have a common cause. Plate interactions commonly cause both earthquakes and volcanoes. Seismology Seismology is the study of earthquakes, and is a subdiscipline within geophysics.

Earthquakes are the result of sudden movements of the Earth, caused by the release of strain that has accumulated over a long time. If the earthquake occurs in a populated area, it may cause deaths, injuries and extensive property damage. The Earth is formed of several layers that have different physical and chemical properties. The outer layer consists of several large, irregularly shaped plates that slide over, under and past each other on top of the partly molten inner layer. Sometimes the movement of the plates is gradual. If the plates are locked together, the energy accumulates until it grows strong enough and the plates break free.

[ TEXT ONLY ] Current Eqs Felt EQs Destructive Eqs Seismicity Hazards, Zoning Instruments HVO electronic technicians upgrading seismic network Earthquakes in Hawai`i are closely linked to volcanism. They are an important part of the island-building processes that have shaped the Island of Hawai`i and the other Hawaiian Islands. Thousands of earthquakes occur every year beneath the Island of Hawai`i. Eruptions and magma movement within the presently active volcanoes (Kilauea, Mauna Loa and Lo`ihi) are usually accompanied by numerous small earthquakes. They originate in regions of magma storage or along the paths that magma follows as it rises and moves prior to eruption. These are loosely termed volcanic earthquakes. Many other earthquakes, including the largest ones, occur in areas of structural weakness at the base of Hawai`i's volcanoes or deep within the Earth's crust beneath the island. These are referred to as tectonic earthquakes. In the past 150 years, several strong tectonic earthquakes (magnitude 6 to 8) caused extensive damage to roads, buildings, and homes, triggered local tsunami, and resulted in loss of life. The most destructive earthquake in Hawai`i's history occurred on April 2, 1868, when 81 people lost their lives. With a magnitude of 7.9 and a maximum intensity of XII, this destructive earthquake destroyed more than a hundred homes and generated a 15-m high tsunami along Kilauea's south coast.

Bridge replacements are needed but traffic flow must be maintained. Bridges must be built to last longer. Construction funds are limited. Accelerated bridge construction helps address these challenges. In her presentation "Successes in Accelerated Bridge Construction," Mary Lou Ralls (Principal, Ralls Newman, LLC) will discuss the nationwide initiative to accelerate bridge construction. She will describe examples of what various states are doing to minimize traffic disruption, improve workzone safety, reduce environmental impacts, and improve quality and constructability by using prefabricated bridge elements and systems for accelerated bridge construction.
