2011 Japan Earthquake and Tsunami


Compiled by Monica Bruckner, SERC.
On March 11, 2011, a magnitude 8.9-9 megathrust earthquake off the north eastern coast of Japan triggered a large tsunami, with wave heights reaching up to 10m. These two events caused widespread devastation and destruction in Japan, including washing away entire cities as well as damaging the country's nuclear power plants, thus causing potential meltdowns.

Visualizations

Ishinomaki Japan Tsunami Before and After Urban 3D Model (more info) This is an urban 3D Model animation showing Ishinomaki, Japan before and after the 2011 tsunami caused severe damage. The before model was created from archival scanned film aerials. The after model was created from Pictometry imagery collected by KKC.

Tsunami Event - March 11, 2011 NOAA Modeling Animations (more info) This website, from NOAA, hosts a collection of links to images, animations, and videos related to the 2011 tsunami in Japan. The graphics display forecast results, showing qualitative and quantitative information about the tsunami, including tsunami wave interaction with ocean floor bathymetric features, and neighboring coastlines. Tsunami model amplitude information is shown color-coded according the scale bar.

How Shifting Plates Caused the Earthquake and Tsunami in Japan (more info) This page features USGS visualizations including a slide show of the sudden movement of the Pacific tectonic plate under the North American plate caused a massive earthquake and a tsunami. It also contains maps of the magnitude of shaking and predicted tsunami wave heights from the March 11, 2011 earthquake and tsunami in Japan.

Honshu Mw=9 Earthquake 11 March 2011 (more info) This web page, from CIRES, provides information, diagrams, and movies related to the March 2011 Japan earthquake and tsunami. These visualizations include mechanisms behind the earthquake and tsunami as well as information about the aftermath of these events. A section on Japan's nuclear power stations and earthquakes is also included.

PPP Kinamatic Solution for the Great Tohoku Earthquake, M9.0 (more info) This website features animations that show coordinate variations every 1 sec. relative to the pre-earthquake a priori coordinates from the March 2011 Japan earthquake. There are four animation movie files available: The top animation shows the co-seismic deformation in a fixed color scale for the entire event and north, east, height components are scaled identically. The deformation is shown in real-time - meaning that every 1-second frame is shown for 1 second. The second animation from the top shows the same but is sped up by a factor of 24. The bottom two animations have an adjusted color scale to emphasize the spatial variability of the seismic waves. Units for the motion are in cm.


The Science Behind the News: Tsunamis (more info) This article, from the Why Files, uses images, diagrams, and video to explain the causes of tsunamis and how we might lessen their cataclysmic potential. It includes information and video of the 2011 Japan tsunami.

Satellite Photos of Japan, Before and After the Quake and Tsunami (more info) Satellite images, taken by GeoEye, from before and after the March 2011 earthquake and tsunami.

Earthquake early warning videos (more info) This web page features videos of the early warning system in action, images of some professional poster presentations, and a description of an in-class kinesthetic activity about how the early warning system works. It also addresses some of the affective aspects of natural disasters.

Post-Earthquake Images of Japan (more info) This web page from Google offers high-resolution imagery, courtesy of their partners at GeoEye, which can be accessed by download a KML file provided on the site and explored in Google Earth. Imagery can also be viewed with Google Maps, or via a link to a Picasa album of before-and-after shots.

Expected wave heights (more info) A map of the expected tsunami waveheights from the Japan earthquake 11 March 2011

Maps of epicenter location, aftershocks, historical seismicity, and more (more info) Maps of epicenter location, aftershocks, historical seismicity, and more related to the 11 March 2011 earthquake off the coast of Japan.

US Groundmotion Video of the Earthquake Event Near the East Coast of Japan (more info) This site, from EarthScope, features a groundmotion movie (Quicktime) of North American crust nearly 6 minutes after the terrible Japan earthquake.

IRIS: Recent Earthquake Teachable Moments (more info) Powerpoint presentations, animations and other visualizations for anyone who wants to teach about the most recent earthquake in the news.

Google Earth Science Seismic Zones (more info) This selection of Google Earth and SketchUp files illustrate and model seismic zones using block models and cross-sections. Regions include Japan, Seattle, the Rockies, San Francisco, Iceland, the New Madrid fault, and I-64 (east coast of US), among others.
