An anniversary is for the Gorkha (Nepal) Earthquake from 1 year ago. I have several Earthquake Reports listed below. These include a variety of observations and comparisons with historic and prehistoric earthquakes that I compiled.

\nHere is the map that I put together. I have placed the USGS epicenters with two color schemes. The size of the yellow dots represents earthquake magnitude. The degree of redness designates the time (earlier-April = pink & later-May = red). Note how there are some pink colored epicenters in the region of the M 7.3 earthquake. These pink colored earthquakes all occurred in April. The red ones are from May. These epicenters may not be plotted with the greatest certainty, though any uncertainty is possibly shared between them. So, there relative positions are possibly good.

\nHere is an updated regional map that incorporates Hough and Bilham (2008 ) and today’s seismicity. The historic and prehistoric earthquake slip patches are also shown. The three other data sets now include Bilham (2004), Bettinelli et al (2006), and Berryman et al. (2009). I provide information about how I compiled these data sets on this page<\/a>.

\nHere is the updated DYFI map. Note how broadly this earthquake was felt.

\nHere are two visualizations of the seismic waves as they propagate through the Earth. These are records from the USArray Transportable Array<\/a>. Your tax dollars at work, unless congress defunds these projects. This first video shows vertical motion as red and blue.

\nThis second video shows horizontal motion with magnitude and direction.
