earthquakesseismic chimneys/ A9130 Seismology A9145 TectonicsSome features of the global distribution of earthquakes are discussed, and symmetry in the global distribution of tectonic fractures is noted. A new notion of seismic chimneys is defined and their role in global tectonics is considered. Deep...

It has sent rescue teams to Nepal, Mozambique, Türkiye and other countries to carry out humanitarian operations following earthquakes and floods, and provided emergency supplies and technical support to Tonga and Madagascar, among other countries. 增强共建国家减贫能力。发展中国家仍面临粮食问题。中国积...
Plate Tectonics Plate tectonics theory explains the global distribution of mountains, earthquakes, volcanoes, ocean basins and rift valleys on the surface of the Earth. What is the theory of plate tectonics? Plate tectonics theory explains that several plates move on top of the soft mantle. Scienti...
Volcanic activity has long been recognized as a source of tsunamis, with volcanic earthquakes, gravitational and caldera collapses, pyroclastic flows, underwater explosions and volcanic blasts constituting the main triggers of volcanic tsunami waves3,4. Typically, most of these mechanisms do not displac...
Gaussian DistributionPlanck’s Length EnergyZero Point Fluctuation FrequenciesQuantum Geophysical EffectsThere has been protracted historical evidence of a relative paucity in the distribution frequency of global earthquakes within the M = 3.5 to 4.0 range. We observed a similar phenomenon for all recently...
The global variation in the space—time distribution of great shallow earthquakes is examined using the surface-wave magnitude M and the magnitude M ω obtained from the seismic moment. In the past several decades, the seismic activity was complementary in the regions of low latitude (<40° ) ...
The Gutenberg-Richter (GR) law is not only of fundamental importance in statistical seismology1 but also a cornerstone of non-linear geophysics2 and complex-systems science3. It simply states that, for a given region, the magnitudes of earthquakes follow an exponential probability distribution. As...

of the disasters we obtained from EM-DAT. In terms of type, droughts are at the lower end with 64% of the events being geocoded, while storms mirror the average at 89.5%. Floods and earthquakes are at the top of the list with shares of 92% and 97% respectively, indicating a skew ...
