Tsunami<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A tsunami signifies a natural calamity where a sequence of large ocean waves are generated, ordinarily having been occasioned by some submarine disturbance such as an earthquake, volcanic eruption, or landslide.<\/li>\n\n\n\n<li>These disturbances displace a huge quantity of water, disallowing waves to travel at speeds of more than 800 kilometers per hour in the open ocean.<\/li>\n\n\n\n<li>In the deep ocean, the tsunami waves usually go unnoticed due to their very low wave heights; they get HUGE somewhere along the coastline and hit to cause devastation.<\/li>\n\n\n\n<li>Inundation from tsunamis, wiping away infrastructure, and taking a good number of lives constitute the men&#8217;s unforeseen fury.<\/li>\n\n\n\n<li>Coastal communities are quite disproportionately affected, requiring preparedness at short notice and sometimes evacuation.<\/li>\n\n\n\n<li>The impact of a tsunami is evident from historic tsunamis such as the Indian Ocean tsunami of 2004, highlighting the imperative of implementing and strengthening an early warning system with disaster-related education for all.<\/li>\n\n\n\n<li>While tsunamis cannot be prevented, knowing about their characteristics will help reduce the damage they cause.<\/li>\n<\/ul>\n\n\n\n<h2

href=\"https:\/\/www.nextias.com\/blog\/volcanism\/\"><strong>volcanism<\/strong><\/a>, landslide, or meteorite impact in the ocean can move huge volumes of water and cause tsunamis.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>High Speed:<\/strong>\n<ul class=\"wp-block-list\">\n<li>The speed of tsunami waves in the deep sea is more than 800 kilometers per hour (500 miles per hour), almost like one of the fastest jet planes.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Long Wavelength:<\/strong>\n<ul class=\"wp-block-list\">\n<li>One special characteristic of tsunami waves is that they have very long wavelengths. They can vary from about 100 kilometers to 500 kilometers, whereas normal ocean waves measure very few meters of wavelength.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Low Wave Height in Deep Water:<\/strong>\n<ul class=\"wp-block-list\">\n<li>In the open ocean, tsunamis generally remain unnoticed with wave heights less than one meter.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Wave Amplification Near Shore:<\/strong>\n<ul class=\"wp-block-list\">\n<li>When the tsunami waves enter these territories of shallow waters near coasts, their velocity is decreased, yet their wave height increases, sometimes even more than 30 meters (100 feet).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Multiple Waves:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Most of the time, a tsunami will consist of a series of waves with the first wave not always being the largest or the most destructive.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Variable Timing:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Time lag between successive waves may be from just a few minutes to many hours-a factor that adds to the unpredictability.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Global Reach:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Across entire ocean basins, tsunamis travel and affect coasts that are away from the original disturbance.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Immense Destructive Power:<\/strong>\n<ul class=\"wp-block-list\">\n<li>The combined energy of tsunami waves can cause widespread devastation, flooding, and erosion upon landfall.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Warning Signs:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Receding ocean water, unusual sounds, and ground shaking near coastlines are natural warning signs of an impending tsunami.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Causes_of_Tsunamis\"><\/span><strong>Causes of Tsunamis<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Underwater Earthquakes:<\/strong>\n<ul class=\"wp-block-list\">\n<li>The most common cause for tsunami is underwater earthquake occuring at tectonic plate boundaries.
