Pangea, supercontinent that incorporated almost all of Earth’s landmasses in early geologic time. Fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago), it began to break apart about 200 million years ago, eventual
a map that portrays the structure of the earth’s crust and, usually, reflects the primary phases in development of the crust within particular regions or for the earth as a whole. Such maps are made on the basis of geologic maps through the use of geophysical and other data. ...
The increase in the number of Earth observation (EO) satellites and shorter revisit periods have facilitated this approach. It is also possible to fetch the archived pre-event satellite images from the past and compare it with the post-event images. However, mapping is a challenging task as ...
earth curvature, and terrain fluctuation. An orthophotograph is a satellite imagery geometrically corrected.Image Interpretation Based on the color and shape reflected on the image, the specific difference of the target electromagnetic wave is inferred, and then the target is qualitatively recognized. Th...
The analysis of on-fault seismicity can enlighten the current stress state on the fault itself. Its definition is relevant to individuate fault patches that have not released all the accumulated stress even after the occurrence of a high magnitude earthq
The map mainly shows 6 parts; distribution of rock and soil mass and their basic engineering geological characteristics; regional stability of earth crust; distribution of major exodynamic geological phenomena; hydrogeological setting; geomorphological conditions; and the main anthropogenic engineering ...
