We believe that the trigger for a catastrophic explosion can be one of the earthquakes preceding the eruption, which resonates with self-oscillations in the peripheral chamber beneath the volcano. This greatly increases the power of the impulse and helps to overcome the energy barrier. It is ...
Every once in a while---after studying the latest behavior of our spinning earth, including the effect of natural phenomena like earthquakes and the gravitational pull on our oceans---a Paris-based organization called the International Earth Rotation and Reference Systems Service, or IERS, tells ...
Global warming, the phenomenon of increasing averageairtemperaturesnear the surface ofEarthover the past one to two centuries. Climate scientists have since the mid-20th century gathered detailed observations of variousweatherphenomena (such as temperatures,precipitation, and storms) and of related influen...
are all social-network phenomena that impact climate change. Finally, in addition to networks of people, society is built by another great network—the global economy (Schweitzer et al.2009) (See Fig.1). Fig. 1 Overview of topics related to climate change that have been studied by networks...
hydraulic shocks (fluid hammer) causing the excitation of the safety system. According to [9], hydraulic shocks are the phenomenon of strong pressure oscillations in a pipe operating under pressure, caused by rapid changes in the velocity of the fluid flow in a short time. The hydraulic shocks...

detectable meteorological phenomena but are a comparatively minor component in atmospheric motions. AnEarth tidediffers from oceanic and atmospheric ones in that the response to it is an elastic deformation rather than a flow. Observations of Earth tides contribute to knowledge of Earth’s internal ...
The causes of the nonuniqueness of the functions describing the frequency and amplitude of the resonant oscillations are analyzed; a generalized definition of the notion of instantaneous frequency is given which takes into account the character of the natural oscillations. Oscillatory systems with varying...
