This blogpost is a round-up of potentially useful weblinks to information about the Sendai, Japan earthquake of 11 March 2011. This post is a summary of what is out there as a resource, not European Geosciences Union endorsed links.
There is a Supersite for the Sendai Earthquake which is a collection of preliminary data and research. This has a lot of information contained within the page and links to other pages.
This includes the USGS event homepage, which has maps of seismic activity and a summary of the event. The USGS also has a map and list of Earthquakes in the Asia region which shows aftershocks.The Japanese Meterology Institute’s page on the Earthquake now has more information. A preliminary model of the faults that were involved in the earthquake can be found at the USGS site .
The Global Disaster Alert and Coordination System has various models related to the earthquake and tsunami.
Various sites have satellite imagery to show the impacts of the Geohazards. NASA’s Earth Observatory has collected it’s images together.
A good summary of the situation at the nuclear power plants can be found at the New York Times webpage.
The Geoblogosphere has covered the events in detail. A clear, brief guide can be found at Scientific American. The AGU blogs cover different aspects of the event: Dave Petley’s Landslide Blog, Callan Bentley’s Mountain Beltway Blog, and Dan Satterfield’s Wild, Wild Science. The Geographile Blog has a video of liquefaction. Interesting information is also to be found on the Berkeley Seismoblog.
[16th March updates]
The International Atomic Energy Agency (IAEA) has updates on the situation at the Nuclear Power Plants. There are live news updates available from many sources including the BBC, the Japan Broadcasting Corporation’s English Pages have several news stories and videos.
SERC has a specific 2011 japan Earthquake adn Tsunami page with teaching resources (visualisations, lesson plans, imagery). Seismograms from the main earthquake and subsequent aftershocks can be seen at Rapid Earthquake Viewer. The Natural Hazards Focus Group at AGU has a Resources Page related to the event (with similar links to this page).
Concerning the Tsunami, the Japanese Meterology Institute issued a major Tsunami warning (with evacuation) only 3 minutes after the earthquake, and provided the estimated time of arrival of the Tsunami at the coast, and its expected height (4 m) after the earthquake. The JMA’s Tsunami forecasting is based on observational network and on efficient models.
At the Sendai Supersite, there are earth observation maps, including several maps of GPS data showing seismic shifting, one map was constructed using 20Hz GPS data of a DLR station (German space agency). Other images that show the impact of earthquake and tsunami include: Flooding along the Kitakami River, Japan, Tsunami Damage near Ishinomaki, Japan, Flooding from Tsunami near Sendai, Japan and Earthquake and Tsunami near Sendai, Japan.
[31 March Update]
Earthquake Reports covers the socio-economic losses, human impacts and general news and analysis of the quake in a series of reports.
