Post updated continuously at the bottom (until I have time)
Hello everyone, I resume the blog with a story heard on the radio while I was having breakfast. This morning to 05:46:23 UTC (6:46 in Italy) an earthquake of magnitude Mw 8.6
Il calcolo del momento tensore effettuato tramite la rete GEOFON dell'Istituto di Posdam ha evidenziato il seguente meccanismo focale:
Tale meccanismo corrisponde ad una sorgente tipo Thrust completamente coerente con la tettonica dell'area.
La profondità dell'evento risulta superficiale e compresa tra 15 Km (Postdam rete GEOFON) e 24 Km (INGV rete MEDNET)

Come generalmente (e direi quasi normalmente) avviene per tutti i terremoti di tipo tettonico, there was a seismic sequence that preceded the main event and a subsequent ongoing. In fact, the main event (main shock) was preceded by a quake of magnitude 7.2 and later by 21 aftershocks of magnitude> 5 (Fore-shocks) and is currently followed by another swarm of adjustment "(After- shocks) of 30 events with magnitude> 5 with at least 13 events up to magnitude greater than 6.
Following the events recorded by the USGS network, for more info (updated), go HERE .

Per i profani della materia, ricordo che i terremoti si possono misurare:
- tramite la stima dei danni (scala Mercalli-Cancani-Sieberg o la scala giapponese JMA) che è fortemente influenzata dalla tipologia delle costruzioni (antisismiche o non) oppure dalla densità delle abitazioni (un forte terremoto nel deserto avrebbe una intensità pari a zero)
Scala Mercalli-Cancani-Sieberg
Scala JMA
- tramite il calcolo della magnitudo (Richter, Momento sismico, Onde volume, Onde L ecc., ovvero il calcolo dell'energia liberata), che è una scala logaritmica e per questo un terremoto è circa trenta volte più energetico per ogni unità di magnitudo (ad esempio un terremoto di magnitudo 5 ha circa trenta volte l'energia di uno di magnitudo 4, un terremoto di magnitudo 6 libera circa mille volte l'energia di uno di magnitudo 4 e così via)

areas nearest the epicenter, the site USGS are Sendai, Iwaki, Koriyama, Mörike, Fukushima, Yamagata.

The quake was strongly also felt in Tokyo where the skyscrapers and ranged where there seems to be a victim (Source Repubblica.it ). At the moment seems to be with an unknown number of wounded.
Also in Tokyo were stopped all the metro lines, railways directed to the north of the country, was interrupted air traffic at the airport, and were stopped nuclear power plants. From the website of the Republic a video of the quake:
authorities and international agencies have now launched the ' tsunami warning in Russian Siberia and the Mariana Islands. Alerted to the island of Guam, the Marshall Islands, Indonesia, Papua New Guinea, Narau, Micronesia and Hawaii. And in fact the tsunami hit, in some areas up to 10 meters high waves crashed onto the shores of the city of Sendai as always to the north island of Honshu, they would have had waves even higher. Here the site of the Republic images and then the video:
Stay tuned for updates (weather permitting)

AGGIORNAMENTO 11/03/2011 alle 11.45
A 4 ore dal sisma ( dal sito di Repubblica ): - Il bilancio del terremoto stilato dai media giapponesi, è di 32 morti
- Lo tsunami (con onde alte fino a 10m) si è spinto fino a 5 chilometri all'interno della prefettura di Fukushima, e c'è la possibilità (ci vorranno ancora diverse ore prima di saperlo) che un'onda anomala potrebbe raggiungere le coste del Cile, infatti il punto più lontano che potrebbe toccare lo tsunami,è fra 23 ore,
- Un inizio di incendio è stato segnalato in un edificio che ospita una turbina Nuclear Power in Onagawa, Miyagi Prefecture
- In Tokyo are burning gas plants.
Let's hope so ......
UPDATE 11/03/2011 at 12.15
And as the mother of idiots is always pregnant ......... could be missing? Cerrrrrto not!!
and in fact sewer on site, it appeared the magic Ron (a Boeotian) supported by the brave komandanten:
The ever-mythical correlation between earthquakes and HARRP .......... In short, the festival of ignorance!
I would point out to everyone that as already in his time sbufalato
- in the post "The illiteracy scientific and geophysical loryyy69 said" the Slave "by Straker "
- and post " Straker ... . increasing scientific illiteracy "
Cheers again
Update 13:30
So
- the dead would be 40 and wounded 39 in the final but I do not think a ship as a with 100 passengers would have been hit by the wave of the tsunami
- E 'was declared the emergency and nuclear power plants were off 4. Government sources seem to have ensured that there were no radioactive leaks.
From the CNN website some very impressive video of the Tsunami:
More from the CNN website some pictures of the earthquake:
Greetings
Update 15:00
Also from the site of the Republic:
- Forty-eight people, including 23 students, are missing after the tsunami arrival at the port of Ofunato, in northeastern Japan.
- Between 200 and 300 bodies were found on a beach in Sendai, on the island of Honshu in the north-eastern Japan, tsunami.
- A train service in the coastal area of \u200b\u200bMiyagi prefecture in northeastern Japan, is currently missing after the tsunami, was in service on the line connecting the cities of Sendai and Ishinomaki.
- The threat has triggered the tsunami warning from Chile to California. and in Hawaii (where it is already there)
- Allo stato attuale sembra che non ci siano fughe radioattive dalle centrali nucleari.
Sul sito ciofeca intanto la sagra dell'idiozia e dell'ignoranza continua la cui chicca è questa :
Si commenta da solo....... (sono proprio bipedi piccoli piccoli)!!
