Secondo test nucleare

[Lorenzo]

Sembra che poche ore or sono la Corea del Nord abbia testato un secondo ordigno nucleare, lo riporta un'agenzia di stampa giapponese:

TOKYO North Korea appeared to have conducted another nuclear test, Japanese broadcaster NHK, a day after China joined other powers calling for a tough response to the communist state's announcement of a first.
Japanese government sources had information that there was a tremor in North Korea and they were checking on the possibility of a nuclear test, NHK said.

Le certezze sul primo test sono ancora davvero poche, alla prima voce che parlava di un'esplosione da 0.5 Kt, se ne sono susseguite altre che parlavano di 4 o 15 Kt.

Se confermata la notizia del secondo test aggraverebbe pesantemente la posizione di Pyonyang.

C'è chi inizia a pensare che siano esplosioni di tritolo. Non capisco perchè la corea non mostri dei video se vuole farsi pubblicità...

La prima esplosione si diceva fosse sotterranea...

Ovviamente. Comunque lo smottamento del terreno è stato filmato, è stato trasmesso persino dalla RAI. Il fetto è che si può simulare una esplosione da 0.5 Kt, ma una da 4 od addirittura 15 Kt diventa impossibile!!

Allarme rientrato si trattava di un terremoto.

A suspected second North Korean nuclear test was reported by the Japanese broadcaster NHK the next day on October 11, 2006. While the Japanese government confirmed there was a tremor, it claimed no knowledge of whether it was due to a nuclear test. The second tremor was a magnitude 5.8, which is larger than the earthquake caused by the first possible nuclear explosion. United States and Republic of Korea sources stated it was unlikely the event was due to a nuclear test.The earthquake did not occur in North Korea but east of Japan in a seismically active area of the Western Pacific ocean.

Un'analisi sulla potenza della deflagrazione:

SYDNEY (Reuters) - North Korea's nuclear test on Monday might have been a "mini-nuke" explosion possibly as low as one kiloton, comparable to some small tests by India and Pakistan in 1998, scientists said on Monday.

The U.S. Geological Survey said it had detected a 4.2 magnitude quake in North Korea at 105 local time (0135 GMT) on Monday, confirming a similar report from South Korea.

Gary Gibson, senior seismologist at Australia's Seismology Research Center, said a 4.2 magnitude quake would be the result of a one kiloton explosion.

"It depends on how the thing is set off. There is not a perfect correlation between magnitude and the yield and depends to some extent on the rock type they set it off in," he said.

"It is a relatively small nuclear test."

The nuclear weapon the United States exploded over Hiroshima in 1945 produced a 12 kiloton yield.

In 1998, India carried out five underground nuclear tests at Pokharan in the western desert state of Rajasthan and declared itself a nuclear weapons state.

The total yield of the first round of blasts measured near 60 kilotons. Two days later, it exploded sub-kiloton devices that scientists said made it capable of conducting computer tests not covered by the Comprehensive Test Ban Treaty.

The United States has said it is interested in developing so-called "mini nukes" -- nuclear weapons with a yield of less of than five kilotons.

Indian nuclear scientists said they thought the North Korean test was an indication that the country was going for smaller devices to ensure effective delivery.

"They are concentrating more on the small devices because of reliability of launching and effectiveness," said A.N. Prasad, former chief of the Bhabha Atomic Research Center, India's top nuclear research facility.

"If the situation demands, they can scale it up, which is not difficult. This is the best approach now."

È sciocco fare delle previsioni, non ci sono abbastanza dati.

Ci sono i dati sismici che possono essere analizzati in base all'analisi della crosta terrestre in quel punto.
