There are several methods (empirical, statistical, and machine learning tools) to calculate blast-induced ground vibration. Still, due to complications in the blasting procedure, under varying

Ground vibration is an integral part of the rock blasting process in surface mines, which may cause severe damages to structures and plants in the nearby environment.

The first Atlas D model flight test missile (3D) had to be destroyed 36 seconds into flight due to a severe engine malfunction and explosions. In addition to other changes, the D series replaced the MA-1 engine package with the Rocketdyne MA-2. The booster engines in the MA-2 produced 309,000 pounds of thrust versus 300,000 pounds for the MA-1.

There were 7 300 fatalities on Turkish roads in , according to the "Global status report on road safety " by the World Health Organization (WHO). Although road deaths in Turkey have decreased steadily to 8.9 per 100 000 of the population in the last ten years, this figure is more than twice as high as in Central European countries.

Coral reefs are coastal resources and very useful for marine ecosystems. Nowadays, the existence of coral reefs is seriously threatened due to the activities of blast fishing, coral mining, marine sedimentation, pollution, and global climate change. To determine the existence of coral reefs, it is necessary to study them comprehensively. One method to study a coral reef by using

Human activity has altered the Earth's vibration wavefield, for example, by generating moderate‐magnitude‐induced earthquakes at frequent intervals [Keranen et al., ], air and ground pressure waves from blasting or aircraft overflights [Hanson et al., 1991], or persistent background vibration from transit sources [Hanson et al., 2006].
