"La notizia delle gravissime conseguenze del sisma che ha colpito il nord-est del Giappone, provocando vittime e grandi distruzioni materiali, mi ha profondamente addolorato". Lo ha scritto il Presidente della Repubblica Giorgio Napolitano nel messaggio inviato all'Imperatore del Giappone, S.M. Akihito.
"In questo momento così drammatico - ha sottolineato il Capo dello Stato - l'Italia, unita al Suo Paese da saldi vincoli di profonda amicizia, si stringe al popolo giapponese.
Con questi sentimenti, desidero trasmetterLe a nome mio personale e di tutto il popolo italiano il più sentito cordoglio e le espressioni di umana solidarietà per le vittime".

Radiation risk
Japan earthquake shuts nuclear facilities but radiation risk unlikely | News | The Engineer
"The massive earthquake that struck off Japan’s northeast coast today has triggered the automatic shutdown of four nuclear power stations, with reports of a non-reactor fire in one and problems with the cooling system in another.
However, there has been no reported leakage of radiation from any of the reactors and based on previous experience of earthquakes at nuclear power plants experts say there is unlikely to be any."

Dedica al Giappone
A un paese che vive le ore peggiori della sua storia moderna dopo lo tsunami che ha causato distruzione e morte.

The United States Geological Survey (USGS) is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. http://www.usgs.gov/

Northern Honshu devastated
"Rescuers struggled to reach survivors on Saturday morning as Japan reeled after an earthquake and a tsunami struck in deadly tandem. The 8.9-magnitude earthquake set off a devastating tsunami that sent walls of water washing over coastal cities in the north. Concerns mounted over possible radiation leaks from two nuclear plants near the earthquake zone."

Karangetang
Just hours after the earthquake stuck Japan, triggering a powerful tsunami, a volcano has erupted in Indonesia. This is one of Indonesia’s most active volcanos, Mount Karangetang

NOAA-DART forecasting
DART (Deep-ocean Assessment and Reporting of Tsunamis) is a service for real-time monitoring the ocean waves. The network has sites positioned at strategic locations throughout the ocean and play a critical role in tsunami forecasting. http://nctr.pmel.noaa.gov/Dart/

"Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. The speed of tsunami waves depends on ocean depth rather than the distance from the source of the wave. Tsunami waves may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters. While tsunamis are often referred to as tidal waves, this name is discouraged by oceanographers because tides have little to do with these giant waves."http://oceanservice.noaa.gov/facts/tsunami.html
