It is a coupled system accounting for both water compressibility and viscoelasticity of the earth. Adding these latter physical effects is responsible for the closest-to-reality time arrival predictions (among existing models), capturing the negative peak before the main wave hump, and the exhibition of the negative dispersion phenomena. This comes in remarkable agreement with previous experiments and studies on the topic. The system is also delivered in a relatively simple mathematical structure of equations that is easy to solve numerically.\u00a0Further well posedness results are also investigated.<\/p>\n<p><strong>Venue:<\/strong> Online via Zoom \/ Sala de Seminarios, 5th floor, Beauchef 851<br \/>\n<strong>Chair:<\/strong>\u00a0Rayssa Caju<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Khawla Msheik (Universit\u00e9 Lyon 1)<\/p>\n","protected":false},"author":85,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[5],"tags":[],"class_list":["post-463","post","type-post","status-publish","format-standard","hentry","category-past-seminar"],"_links":{"self":[{"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/posts\/463","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/users\/85"}],"replies":[{"embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/comments?post=463"}],"version-history":[{"count":2,"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/posts\/463\/revisions"}],"predecessor-version":[{"id":465,"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/posts\/463\/revisions\/465"}],"wp:attachment":[{"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/media?parent=463"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/categories?post=463"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/pdeseminar\/wp-json\/wp\/v2\/tags?post=463"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
