Damage estimates released Thursday by the Hokkaido government show tsunami could kill 149,000 people in the event a major earthquake hits off Japan's northernmost main island, surpassing a central government prediction by around 12,000. But the report also said deaths could be significantly reduced if thorough evacuation measures are swiftly…
The Supreme Court apparently does not accept that the government has a responsibility to do everything possible to prevent a nuclear accident that could cause irreparable harm not only to human life and health but also to the environment.
We present the conjugated ionospheric total electron content (TEC) anomalies prior to the 2011 Mw9.0 Tohoku-oki earthquake, Japan, observed by the Global Navigation Satellite System (GNSS) stations in northern Australia. The onset time of the anomaly, determined by the Akaike’s information criterion, is 41.5 minutes before the earthquake in Australia, which is very close to the time observed in Japan. The positive TEC anomalies in Australia emerged on the same longitude as the land area of NE Japan. This supports the model that electric fields within the ionosphere redistributed the electrons immediately before large earthquakes. However, the observed anomaly is shifted equatorward by ~500 km reflecting the difference in physical mechanisms between the two hemispheres. We also found that the geomagnetic declination near the conjugate point simultaneously started to change ~40 minutes before the earthquake, but its physical implication is yet to be explored.
