What was the `shock wave` that we saw in the devastating Beirut explosion?

<p style=";text-align:left;direction:ltr"> <strong>Arab Weather</strong> - During the Beirut explosion on Tuesday 4 August 2020, we saw the shock wave that appeared before the &quot;mushroom cloud&quot; that formed after the explosion. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D8%A7%D9%86%D9%81%D8%AC%D8%A7%... huge Beirut explosion shows that the &quot;mushroom clouds&quot; are not only related to the nuclear explosions ... so what is a mushroom cloud or mushroom?</a> </p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> <strong>So what is a shock wave?</strong> </h2><p style=";text-align:left;direction:ltr"> A shock wave is a strong pressure wave that occurs in any flexible medium such as air, water, or solid matter, produced by supersonic aircraft, explosions, lightning strikes, or other phenomena that create violent changes in pressure. </p><p style=";text-align:left;direction:ltr"><img alt="" src="/sites/default/files/uploads-2017/shockwave.jpg" style="width: 800px; height: 450px;" /></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Does the shock wave resemble a sound wave?</strong> </h3><p style=";text-align:left;direction:ltr"> Shock waves differ from sound waves in that the wave front, in which pressure occurs, is a region of sudden and violent change in stress, intensity, and temperature. Because of this, shock waves propagate in a different way than normal sound waves. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Shock waves travel faster than sound, and their speed increases with increasing amplitude; But the intensity of the shock wave also decreases faster than the sound wave, because some of the shock wave energy goes into heating the medium in which it is traveling. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Shock waves change the mechanical, electrical and thermal properties of solid materials, and thus can be used to study the equation of state (relationship between pressure, temperature, and volume) for any substance <span>.</span> </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D9%86%D8%AA%D8%B1%D8%A7%D8%AA-... nitrate.
