Earth Sciences (also referred to as Geosciences), which deals with basic issues surrounding our planet, plays a vital role in the area of energy and raw materials supply.
Earth Sciences comprises subjects such as geology, geography, geological informatics, paleontology, mineralogy, petrography, crystallography, geophysics, geodesy, glaciology, cartography, photogrammetry, meteorology and seismology, early-warning systems, earthquake research and polar research.
Events rare, but scientists call for public awareness, warning system
A dozen major earthquakes of magnitude 7.0 or greater have occurred in the Caribbean near Puerto Rico, the U.S. Virgin Islands and the island of Hispaniola, shared by Haiti and the Dominican Republic, in the past 500 years, and several have generated tsunamis. The most recent major earthquake, a magnitude 8.1 in 1946, resulted in a tsunami that killed a reported 1,600 people.

On Tuesday 21th of December 2004 a European team involved in Epica (European Project for Ice Coring in Antarctica) reached the drilling depth of 3270.2, which is five meters above the bedrock at Dome C, on the central plateau of the east Antarctic ice sheet. The ice is melting at the bedrock and it has been decided to stop at this depth to avoid any danger of direct contamination of the basal water. The drilling operation has therefore been terminated.
The drilling has been very successfu
The immediate response by the European Commission’s Joint Research Centre has consisted of:
* Analysis of regional maps depicting Tsunami flooded zones, affected population and natural resources.
A preliminary estimate of the inundation zone was produced by calculating the area of less than 10m and 20m elevation contour lines within 5km of the coastline for the entire region. This information was cross-checked with global population density data to estimate the likely population
College and high school students can now see how Earths climate is changing without leaving their computers.
NASA and other organizations use NASAs global climate computer model (GCM) to see how Earths climate is changing. A GCM calculates many things, such as how much sunlight is reflected and absorbed by Earths atmosphere, the temperature of the air and oceans, the distribution of clouds, rainfall, and snow, and what may happen to the polar ice caps in th
People that live in Florida would expect the sands from the state beaches to blow into the air, and usually don’t think of the sands and dust from the Saharan Desert twirling around them. However, winds do carry the desert dust across the Atlantic Ocean, and scientists have been studying what they do to Florida Thunderstorms.
Scientists have discovered that these tiny particles of dust from the Saharan desert can affect thunderstorms in Florida in various ways. Dust affects
NASA scientists using data from the Indonesian earthquake calculated it affected Earths rotation, decreased the length of day, slightly changed the planets shape, and shifted the North Pole by centimeters. The earthquake that created the huge tsunami also changed the Earths rotation.
