It is used above all in Seismic Zoning studies and for designing anti-seismic buildings. The versatility of this surveying method is also exploited to obtain the resonance frequencies of a building, which is then compared to that of the land. The technique involves obtaining recordings of environmental noise using a digital tromometer, connected to a seismograph.<\/span><\/div>\n<p>[\/vc_column_text][vc_empty_space empty_h=&#8221;2&#8243;][vc_custom_heading heading_semantic=&#8221;h4&#8243; text_font=&#8221;font-377884&#8243; text_size=&#8221;h4&#8243; text_weight=&#8221;600&#8243; text_transform=&#8221;uppercase&#8221; css_animation=&#8221;curtain-words&#8221; uncode_shortcode_id=&#8221;139061&#8243;]fields of application:[\/vc_custom_heading][vc_row_inner][vc_column_inner column_width_percent=&#8221;100&#8243; gutter_size=&#8221;0&#8243; style=&#8221;dark&#8221; overlay_alpha=&#8221;50&#8243; shift_x=&#8221;0&#8243; shift_y=&#8221;0&#8243; shift_y_down=&#8221;0&#8243; z_index=&#8221;0&#8243; medium_width=&#8221;0&#8243; mobile_width=&#8221;0&#8243; css_animation=&#8221;right-t-left&#8221; width=&#8221;1\/1&#8243; uncode_shortcode_id=&#8221;111447&#8243;][vc_column_text border_color=&#8221;color-165788&#8243; border_style=&#8221;solid&#8221; uncode_shortcode_id=&#8221;179663&#8243; css=&#8221;.vc_custom_1637762470837{border-top-width: 0px !important;border-right-width: 0px !important;border-bottom-width: 2px !important;border-left-width: 0px !important;padding-top: 10px !important;padding-bottom: 10px !important;}&#8221; border_color_type=&#8221;uncode-palette&#8221;]Seismic Microzoning[\/vc_column_text][vc_column_text border_color=&#8221;color-165788&#8243; border_style=&#8221;solid&#8221; uncode_shortcode_id=&#8221;682253&#8243; css=&#8221;.vc_custom_1637278327195{border-top-width: 0px !important;border-right-width: 0px !important;border-bottom-width: 2px !important;border-left-width: 0px !important;padding-top: 10px !important;padding-bottom: 10px !important;}&#8221; border_color_type=&#8221;uncode-palette&#8221;]Identification of the site&#8217;s natural frequency[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row row_height_percent=&#8221;0&#8243; override_padding=&#8221;yes&#8221; h_padding=&#8221;2&#8243; top_padding=&#8221;3&#8243; bottom_padding=&#8221;4&#8243; back_color=&#8221;color-172302&#8243; back_image=&#8221;105201&#8243; back_position=&#8221;center bottom&#8221; overlay_alpha=&#8221;50&#8243; gutter_size=&#8221;3&#8243; column_width_percent=&#8221;100&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; uncode_shortcode_id=&#8221;152544&#8243; back_color_type=&#8221;uncode-palette&#8221;][vc_column column_width_percent=&#8221;100&#8243; position_vertical=&#8221;bottom&#8221; gutter_size=&#8221;2&#8243; [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":106491,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"inline_featured_image":false,"footnotes":""},"class_list":["post-106540","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/pages\/106540","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/comments?post=106540"}],"version-history":[{"count":9,"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/pages\/106540\/revisions"}],"predecessor-version":[{"id":107478,"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/pages\/106540\/revisions\/107478"}],"up":[{"embeddable":true,"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/pages\/106491"}],"wp:attachment":[{"href":"https:\/\/geosurveys.it\/en\/wp-json\/wp\/v2\/media?parent=106540"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
