Crustal stretching Seismic Interpretation By: Donovan Durham Introduction The Caledonian orogeny happened during the late Silurian to early Devonian periods. This was due to the westward subduction of Baltican plate beneath the Laurentian margin. The continent to continent orogeny resulted in a over thickened crust. During the Palezoic orogeny several different processes were at work simultaneously‚ which included erosion‚ plate divergence‚ gravity driven collapse of the orogenic wedge‚ and

Formation of Volcanic Islands When people think of volcanoes‚ most would imagine a deadly explosion of liquid hot magma that ruthlessly obliterates anything in plain view. If volcanoes demolish everything in sight then how did life become what it is today? Volcanoes are not just a source of destruction and mayhem‚ long before civilization‚ while the earth was still being developed its apocalyptic surface consisted of nothing but molten rock and volcanic eruptions were a common occurrence; it was

Seismic hazards have many different impacts around the world. An earthquake took place in Haiti 2010 and it was measured 7 on the Richter scale. The main hazard was the seismic waves caused by shifting rocks in an earthquake. There are two main types of waves‚ P waves and S waves. P waves travel through solids and liquids around 6-7 km/h and parallel through the rocks. S ways travel side ways at 2.5-4km/h and can only get through solids. Both waves can have a big impact on the community‚ a lot of

is now known as the volcanic eruptions on the Greek island of Santorini‚ previously known as Thera‚ suggest that the estimated 1600 BC eruptions may be one of the most catastrophic natural disasters in human history.1 Conflicting beliefs of the timing of the event have been made. The debate of the traditional 1500 BC‚ and the earlier date emanate from the finding of an olive branch buried beneath lava‚ which radiocarbon dating has estimates is from 1627-1600 BC.2 The event produced widespread effects

Seismic waves‚ which are waves of energy that travel through the earth‚ and are a result of an earthquake‚ explosion‚ or a volcano that imparts low-frequency acoustic energy. There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When
