(CTBTO)<\/strong> is hosting a workshop for scientists focused on <strong>infrasound research<\/strong> and its operational capabilities in global and regional networks.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What is Infrasound?\u00a0<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Infrasound refers to <strong>low-frequency sound waves<\/strong>, which are the opposite of ultrasound (high-frequency sound waves).<\/li>\n\n\n\n<li>These waves can be generated by natural phenomena like meteors, storms, auroras, volcanoes, earthquakes, and nuclear explosions.<\/li>\n\n\n\n<li><strong>Historical Observation:<\/strong>The first recorded infrasound observation occurred after the 1883 Krakatoa volcano eruption, where the waves circled the globe and caused widespread damage.<\/li>\n\n\n\n<li><strong>Applications<\/strong>: Infrasound can be used to check the structural health of buildings, dams, bridges, and aerospace applications like rocket stress detection and aircraft instability.\n<ul class=\"wp-block-list\">\n<li>It is also used in mining to check mine shaft integrity and for wildlife tracking, such as monitoring whale movements<\/li>\n\n\n\n<li>Infrasonic waves cause minute changes in atmospheric pressure, which can be measured by microbarometers.<\/li>\n\n\n\n<li>These waves travel long distances without losing energy, making them useful for detecting distant nuclear explosions.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Health Concerns:<\/strong>There are concerns about unknown effects of infrasound on human health, though this remains a topic of ongoing debate.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>About CTBTO\u2019s Mandate:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The CTBTO&#8217;s main goal is to get more countries, including India, to sign the <strong>Comprehensive Nuclear-Test-Ban Treaty (CTBT)<\/strong>.<\/li>\n\n\n\n<li>The organization shares its monitoring technologies, including infrasound, with industries.<\/li>\n\n\n\n<li>The CTBTO\u2019s International Monitoring System (IMS) is building the only global infrasound network, with 60 array stations planned across 35 countries.\n<ul class=\"wp-block-list\">\n<li>Each array consists of several elements, a meteorological station, a processing facility, and a communication system for data transmission.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>The CTBTO workshop aims to enhance understanding of infrasound, with the goal of making it as common in usage as ultrasound.<\/li>\n<\/ul>\n\n\n\n<p>Source : BL<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><strong>Legacy waste management project of the Swachh Bharat Mission
