Nonlinear acoustic waves in the viscous thermosphere and ionosphere above earthquake
(American Geophysical Union, 2016-12)
The nonlinear behavior of acoustic waves and their dissipation in the upper atmosphere is studied on the example of infrasound waves generated by vertical motion of the ground surface during the Mw 8.3 earthquake that ...
Estudo da geração de infrassom com diferentes tipos de transdutores
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia de Controle e AutomaçãoUTFPR, 2017-05-22)
A characteristic of infrasound is the induction of vibratory sensation. In this study, the sound pressure level at very low frequencies necessary to produce a vibratory sensation on a person was investigated. For this, ...

Dynamics of soap bubble bursting and its implications to volcano acoustics
(2010-04-14)
In order to assess the physical mechanisms at stake
when giant gas bubbles burst at the top of a
magma conduit, laboratory experiments have been
performed. An overpressurized gas cavity is initially
closed by a thin ...
The use of Digital Sound in Health
(Ios Press, 2013-01-01)
With the advent of computing and micro computing, several applications based on Digital Sound have emerged around the world. Much analog equipment and electronics have gained new functions due to evolution and the low cost ...
The Carancas meteorite impact crater, Peru: Geologic surveying and modeling of crater formation and atmospheric passage
(The Meteoritical SocietyUS, 2009-07)
The recent Carancas meteorite impact event caused a worldwide sensation. An H4–5 chondrite struck the Earth south of Lake Titicaca in Peru on September 15, 2007, and formed a crater 14.2 m across. It is the smallest, ...

Volcano hazard and surveillance in Costa Rica
(2021-11-01)
Costa Rica hosts ten volcanic complexes and is highly tectonically active due to its location at the interaction between the Cocos, Nazca, and Caribbean plates and the Panama microplate. Three of the five historically ...
