in its most generic sense, the word earthquake is used to describe any seismic event—whether a natural phenomenon or an event caused by humans—that generates seismic waves. earthquakes are caused mostly by rupture(破裂, 裂开) of geological faults(断层), but also by volcanic activity, landslide...
In January, the USGS estimated that nearly 75% of the U.S. could experience a damaging earthquake in the next century. The prediction is based on research done by dozens of scientists and engineers using seismic studies, historical geological data and new information to identify nearly 500 addit...
Today’s GIS has become ubiquitous. Open-source GIS data from the United States Geological Survey (USGS) and other agencies, and GIS applications (such as QGIS) and their tutorials are easily accessible. Outside of government and academic settings, GIS is used to track packages, route trips ...

One of the most debated questions in geological sciences is: what is the age? The age of a particular event, the age of a remarkable discovery, the age of aStratigraphy, Quaternary
as color, height of a digital innovation model, and several variables is attached to every grid cell. Examples include thematic maps, digital elevation model/ digital surface model (DEM/DSM), remote sensing (RS) images, photogrammetric photos, scanned maps, geophysical images, and geological maps...
Examples include thematic maps, digital elevation model/ digital surface model (DEM/DSM), remote sensing (RS) images, photogrammetric photos, scanned maps, geophysical images, and geological maps. Raster data types are large and have a very different data structure compared to vector data types. ...
Geological extinction Genetic diversity Species age Endemism Remnant Introduction Why does phylogenetic diversity (or evolutionary distinctiveness) dramatically matter for biodiversity conservation? The answer to this question first posed by Vane-Wright et al. (1991) and Faith (1992) is often illustrated ...
Deeper in time, a mass extinction event that ended the Devonian Period, a geological erawhen life thrived on landfor the first time, was also attributed to a hyperthermal eventlikely triggered by volcanic activity 359 million years ago, according to Benton’s book. ...
