Related to diastrophism: volcanism, epeirogenic


The process of deformation by which the major features of the earth's crust, including continents, mountains, ocean beds, folds, and faults, are formed.

[From Greek diastrophē, distortion, from diastrephein, to distort : dia-, apart; see dia- + strephein, to twist; see streb(h)- in Indo-European roots.]

This is due to the possibility of continuous communication in the absence of sudden incidents, such as changes in sensor location or diastrophism, because the communication objective is a common goal and sensors are placed at fixed locations in WSN environments.
Additionally, under the action of anchoring force, the shearing strength between any two rock strata also increases, inhibiting the horizontal diastrophism between any two strata and forming a thick combined rock beam via anchoring within the anchorage range and finally significantly improving the stability of roadway roof [31].
Meanwhile, comparative analysis on specimens of 12 h, 24 h, 36 h, and 48 h shows that no segregation or diastrophism appears in layered surface of the destructive specimens and the specimens are integrated overall, which is obviously different from specimens under different filling times.
