Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. For an explosion to occur, there must be a rapid, forceful expansion of matter.

The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982.

May 7, 2004 · Current understanding of the size and frequency of the Earth’s largest explosive eruptions is limited. Despite the potential impact of such events, only a handful of these eruptions have been studied in any detail. There have been few attempts to develop a systematic dataset to allow comparison between, and analysis of such events.

May 10, 2024 · We demonstrate that their size, frequency, and composition can be explained by processes in long-lived, high-crystallinity source reservoirs that control the episodic creation of large volumes of eruptible silicic magma and its delivery to the subvolcanic chamber where it is stored before eruption.

The Cambrian explosion (also known as Cambrian radiation[1] or Cambrian diversification) is an interval of time beginning approximately 538.8 million years ago in the Cambrian period of the early Paleozoic, when a sudden radiation of complex life occurred and practically all major animal phyla started appearing in the fossil record. [2][3][4] It...

May 1, 2005 · An analysis of the size and frequency of the largest known explosive eruptions on Earth reveals 42 known eruptions with erupted masses in excess of 1015 kg (magnitude 8 or larger) in the past 40...

Explozia (din fr. explosion, lat. explosio) este un proces fizico-chimic de ardere cu descompunere foarte rapidă, violentă, a substanțelor explozive și de transformare a lor în alți compuși, mai simpli, ea fiind însoțită de efecte intense mecanice, sonore, termice și luminoase.

Sep 13, 2024 · Cum funcționează o explozie nucleară: puterea atomului dezlănțuită. O explozie nucleară apare în urma eliberării bruşte a unei cantități uriașe de energie din reacții nucleare, fie prin fisiunea atomilor, fie prin fuziunea lor.

Explozia este o reacție chimică sau fizică foarte rapidă, violentă, însoțită de efecte mecanice, sonore, termice, luminoase, provocate de descompunerea substanțelor explozive pe care le conține un dispozitiv de distrugere; explodare, detonație, fulminație.
