I have several reports from previous years that have reviews of the earthquake and tsunami.<\/p>\n
- \n
- This is the primary page where I present a comprehensive summary<\/a> of our findings as of a few years ago.<\/li>\n<\/ul>\n
I focus mostly on new material I prepared for the following report.<\/p>\n
Updated Interpretive Poster <\/font><\/h3>\n
- \n
- I plot the seismicity from the year after the M 9.1, as well as large events from the past century, with diameter representing magnitude (see legend). <\/li>\n
- I plot the USGS fault plane solutions (moment tensors in blue and focal mechanisms in orange), possibly in addition to some relevant historic earthquakes. <\/li>\n
- A review of the basic base map variations and data that I use for the interpretive posters can be found on the Earthquake Reports page<\/a>. I have improved these posters over time and some of this background information applies to the older posters.<\/li>\n
- Some basic fundamentals of earthquake geology and plate tectonics can be found on the Earthquake Plate Tectonic Fundamentals page<\/a>.<\/li>\n<\/ul>\n

- In the upper left corner is a small scale plate tectonic map showing the plate boundary faults with the magnetic anomalies overlain in transparency. There is an inset low angle oblique illustrative map showing how these plates interact in the subsurface (Lin et al., 2016).<\/li>\n
- In the lower right corner is a map that shows a comparison between the USGS modeled earthquake intensity and the USGS Did You Feel It? observations. These data are also included in a web map lower down in this update.<\/li>\n
- To the left of the intensity map are two tide gage plots that show a tsunami record. The upper plot is from Crescent City, California. The lower plot is from Naha, a location southwest of the earthquake, labeled on tectonic map. These and other tide gage records are viewable in the tide gage web map below.<\/li>\n
- In the upper right corner are two maps displaying the results from ground failure models from the USGS. The map on the left shows the potential for landslides triggered by the M 9.1 earthquake. The map on the right shows the chance that an area may have experienced liquefaction. These are included in a web map below.<\/li>\n<\/ul>\n

- Here is the map with a year’s and century’s seismicity plotted.<\/li>\n

Web Map<\/strong><\/h3>\n
Use this map to see the magnitudes of different earthquakes experienced in Japan. The map shows earthquake epicenters for large-magnitude historic events of the past century. It also includes epicenters for all aftershocks and triggered earthquakes for a year after the M 9.1 earthquake, and an outline of the aftershocks, which illustrates the area of the fault that slipped during the M 9.1 earthquake.<\/p>\n
