Such a wave travels at well over 800 kilometres per hour (500 mph), but owing to the enormous wavelength the wave oscillation at any given point takes 20 or 30 minutes to complete a cycle and has an amplitude of only about 1 metre (3.3 ft).<sup id="cite_ref-58" class="reference"><a href="#cite_note-58"><span class="cite-bracket">[</span>58<span class="cite-bracket">]</span></a></sup> This makes tsunamis difficult to detect over deep water, where ships are unable to feel their passage. </p><p>The velocity of a tsunami can be calculated by obtaining the square root of the depth of the water in metres multiplied by the acceleration due to gravity (approximated to 10 m/s<sup>2</sup>). For example, if the Pacific Ocean is considered to have a depth of 5000 metres, the velocity of a tsunami would be <span class="nowrap">√<span style="border-top:1px solid; padding:0 0.1em;">5000 × 10</span></span> = <span class="nowrap">√<span style="border-top:1px solid; padding:0 0.1em;">50000</span></span> ≈ 224 metres per second (730 ft/s), which equates to a speed of about 806 kilometres per hour (501 mph).

Since the wave still has the same very long <a href="/wiki/Frequency" title="Frequency">period</a>, the tsunami may take minutes to reach full height.

In the case of a propagating wave like a tsunami, either may be the first to arrive. If the first part to arrive at the shore is the ridge, a massive breaking wave or sudden flooding will be the first effect noticed on land. However, if the first part to arrive is a trough, a drawback will occur as the shoreline recedes dramatically, exposing normally submerged areas. The drawback can exceed hundreds of metres, and people unaware of the danger sometimes remain near the shore to satisfy their curiosity or to collect fish from the exposed seabed. </p><p>A typical wave period for a damaging tsunami is about twelve minutes. Thus, the sea recedes in the drawback phase, with areas well below sea level exposed after three minutes. For the next six minutes, the wave trough builds into a ridge which may flood the coast, and destruction ensues. During the next six minutes, the wave changes from a ridge to a trough, and the flood waters recede in a second drawback. Victims and debris may be swept into the ocean. The process repeats with succeeding waves. </p> </section><div class="mw-heading mw-heading2 section-heading" onclick="mfTempOpenSection(6)"><span class="indicator mf-icon mf-icon-expand mf-icon--small"></span><h2 id="Scales_of_intensity_and_magnitude">Scales of intensity and magnitude</h2></div><section class="mf-section-6 collapsible-block" id="mf-section-6"> <p>As with earthquakes, several attempts have been made to set up scales of tsunami intensity or magnitude to allow comparison between different events.<sup id="cite_ref-Gusiakov_65-0" class="reference"><a href="#cite_note-Gusiakov-65"><span class="cite-bracket">[</span>65<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Intensity_scales">Intensity scales</h3></div> <p>The first scales used routinely to measure the intensity of tsunamis were the <i><a href="/wiki/August_Heinrich_Sieberg" title="August Heinrich Sieberg">Sieberg</a>-<a href="/wiki/Nicholas_Ambraseys" title="Nicholas Ambraseys">Ambraseys</a> scale</i> (1962), used in the <a href="/wiki/Mediterranean_Sea" title="Mediterranean Sea">Mediterranean Sea</a> and the <i>Imamura-Iida intensity scale</i> (1963), used in the Pacific Ocean.

However, there are some warning signs of an impending tsunami, and automated systems can provide warnings immediately after an earthquake in time to save lives. One of the most successful systems uses bottom pressure sensors, attached to buoys, which constantly monitor the pressure of the overlying water column. </p><p>Regions with a high tsunami risk typically use <a href="/wiki/Tsunami_warning_system" title="Tsunami warning system">tsunami warning systems</a> to warn the population before the wave reaches land. On the west coast of the United States, which is prone to tsunamis from the Pacific Ocean, warning signs indicate evacuation routes. In Japan, the populace is well-educated about earthquakes and tsunamis, and along Japanese shorelines, tsunami warning signs remind people of the natural hazards along with a network of warning sirens, typically at the top of the cliffs of surrounding hills.<sup id="cite_ref-Chanson_2010_76-0" class="reference"><a href="#cite_note-Chanson_2010-76"><span class="cite-bracket">[</span>76<span class="cite-bracket">]</span></a></sup> </p><p>The <a href="/wiki/Pacific_Tsunami_Warning_Center" title="Pacific Tsunami Warning Center">Pacific Tsunami Warning System</a> is based in <a href="/wiki/Honolulu" title="Honolulu">Honolulu</a>, <a href="/wiki/Hawaii" title="Hawaii">Hawaiʻi</a>.
