We propose a method to measure the energy distribution of low-energy flares (nanoflares) in range below 1023 erg. As an example, we measured spectrum nanoflares 1021–1026 erg for two Sun’s frames observed by SDO/AIA telescope 171 Å channel. Nanoflares are shown have power law 1022–1026 range. The spectral index is approximately constant, i.e. energy-independent. For energies 1022 erg, begins co...

a considerable amount of energy is released in the form of shock wave from explosive charge detonation. shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. the rest of the shock wave energy is transferred to rock mass as ground vibration. ground vibration is conveyed to the adjacent structures by body and surface waves. geological structures li...
