Source inversion of W phase: speeding up seismic tsunami warning
S U M M A R Y W phase is a long period phase arriving before S wave. It can be interpreted as superposition of the fundamental, first, second and third overtones of spheroidal modes or Rayleigh waves and has a group velocity from 4.5 to 9 km s−1 over a period range of 100–1000 s. The amplitude of long period waves better represents the tsunami potential of an earthquake. Because of the fast gro...

متن کاملTsunami warning system using of IoT
Abstract Today, the world has reached a new nature with advances in science. The Internet of Things is a technology that can connect all objects in different fields through the Internet. Any unforeseen event that destroys economic, social and physical capabilities and inflicts human and financial losses is known as a natural disaster, such as a tsunami. IoT-based tsunami forecasting system ...
متن کاملProposed Use of the T Phase in Tsunami Warning Systems
A STRIKING correlation between the occurrence of a short-period earthquake phase (T phase) traveling through the ocean with the speed of sound in sea water and the occurrence of tsunamis has been observed. The characteristics of the T phase are described and the data upon which the correlation is based are presented. Although further study is needed, the evidence at hand warrants the inclusion ...
متن کاملInvestigation of the effect of different parameters on the phase inversion temperature O/W nanoemulsions
Objective(s): Nanoemulsions are a kind of emulsions that can be transparent, translucent (size range 50-200 nm) or “milky” (up to 500 nm). Nanoemulsions are adequatly effective for transfer of active component through skin which facilitate the entrance of the active component . The transparent nature of the system and lack of the thickener and fluidity are among advantages of nanoemulsion. Mate...
