Rusia invade Ucrania. Hilo general vol. 2

#16808 Estaria guay que alguien que sepa de física explicara como un arma que libera mucha, pero mucha menos energía que un terremoto típico puede causar un maremoto que destruya un país.

#16813
Es por la cantidad de agua que desplazas.

Hay muchos terremotos que pasan en el mar y no provocan un tsunami, porque no desplazan grandes cantidades de agua al producirse.

Vease cuando una falla por subduccion cede, dependiendo de la fuerza con la que haya desplazado el agua, pues tendras un tsunami top, o unas olitas que ni te das cuenta.

#16815 Entonces tendriamos que suponer que los rusos no solo saben diseñar un arma así, sino que tambien saben donde lanzarla exactamente para provocar un tsunami catastrófico y que la OTAN no es capaz de mantener vigiladas esas zonas. Eso sin mencionar que el MAD sigue ahí.

No me preocupa mucho la verdad y me da que si a la OTAN le preocupase se callarian en vez de denunciarlo.

Como de los articulos de noticias ni con un palo y no creo que haya papers de este tema copio un post de alguien que parece bastante instruido en el tema:

Claim ‘It really can cause 500m tall tsunami waves which can flood the whole of the UK’

Let me explain to you why that is a pile of BS.

Tsunamis are large waves caused by gigantic disturbances to huge layers of water. They are commonly caused by earthquakes, although the biggest can be caused by meteorites and landslides.

The Russian underwater phallus by the name Status-6, or Poseidon, has a nuclear warhead estimated at 2–100 Mt of TNT. If we take the upper bound, then that means that a detonation of Status-6 is like 2 Tsar Bombas exploding.

Alas, even that sort of monstrous energy, which is enough to completely vapourise a massive volume of water, is not anywhere near enough to cause a 500m tall tsunami. Heck, it cannot even cause a tsunami of normal magnitude!

The 2004 Indian ocean earthquake caused a tsunami which led to the deaths of 227,898 people. The maximum wave height during the tsunami was seen in Indonesia, right by the epicenter, with waves reaching 30 meters tall with a biggest run-up height of 51 meters. 1,700km away, the waves had a height of 9 meters. The energy released by this earthquake has been calculated to be 0.8 gigatons of TNT, or the equivalent of 8 upper-bound Poseidons exploding at once.

Poseidon simply cannot release enough energy to disturb enough water to cause such a tsunami. It cannot cause 30m waves, let alone 500m waves. In order to cause a wave on the order of half a kilometer in height, you will need an asteroid. The Chicxulub impact is thought to have been able to cause tsunamis several kilometers high if it struck the deep ocean. The impact generated 100 teratons of TNT equivalent in energy. In order for Russia to be able to cause such a wave, it would need to detonate a million Poseidons at once.

But this equivalence is a crude estimate assuming that all the energy in both earthquake and explosion goes into disturbing water. Whilst a 100Mt warhead at the depth may cause huge disturbances of water, it is unlikely to trigger anything beyond a meteotsunami, and this is assuming it dives to the seafloor. The maximum depth of Status-6 is 1,000 meters, not enough to reach the seafloor in the deep Atlantic ocean. Whilst it can reach the bottom of the North Sea, it simply does not have enough energy to cause a 30m high tsunami by itself.

If the device is detonated by the coast, as some Russian outlets seem to claim, the effect of the detonation will be even more useless. The United States detonated a 15 Mt device underwater in shallow waters, which caused a tiny tsunami, which rapidly dissipated.

If Russia orders 30 as it plans, unlikely with sanctions, it still won’t be able to do much beyond triggering tsunamis of the scale seen in the Indian ocean. To me that is an immense waste of resources and precious warheads. Yes it will kill people, but it also won’t kill anyone several miles from the coast, and the death toll is going to be enormously smaller than the result of a single US warhead detonating in Moscow.

What concerns the sci-fi descriptions of a 500m wave hundreds of kilometers from the epicenter contaminating everything with radiation- that is the stuff of myth, sort of like zigzagging Russian hypersonic weapons dodging missiles every few meters. Moreover, a tsunami caused by this device will not be radioactive.

Besides, if a tsunami is detected, there is infrastructure in place to detect it and start an evacuation

As for detecting the device, yes it can readily be detected, and I suspect given its size and lack of acoustic damping the US and NATO will be able to easily hunt down and destroy these torpedoes. The US estimates that it can be detected at speed 40km away. 40km from the coast, unless it happens on the West Coast, will not cause a high tsunami at all. And if it does happen on the West Coast, everyone will be evacuated before the wave hits.

Pregunto opiniones ya que ninguno sabemos que pasará, pero veis real que Rusia vaya a tirar de nucleares?por un lado está hablando mucho a ver si infunde miedo, mi opinión es que si sigue perdiendo territorio así podría usarla, lo que me cuesta creer es que EEUU vaya a responder, no soy ningún experto pero escuchando podcast etc si que veo posible que tire de nukes
