Every California Earthquake of the Last 30 Years

A new video from the Pacific Tsunami Warning Center maps every earthquake recorded in California in the last 30 years.  Check it out below.

The video starts in August 1989 and ends July 5, 2019 with the magnitude 7.1 quake in Ridgecrest.  The largest earthquake in the last 30 years was the magnitude 7.3 quake in the small Mojave Desert town of Landers in June 1992.

There is a composite image at the end of the video of all earthquakes, and really there are only a few areas in California that are earthquake free!

2019 StoryMapper of the Year Contest

To give you the opportunity to demonstrate your skills using this next generation story builder, ESRI invites you to enter the 2019 StoryMapper of the Year Contest. The contest will also give you the chance to give back to your community at the same time!

The StoryMapper of the Year Contest started July 8, 2019, and the deadline for submission is 5:00 p.m. (PDT), September 30, 2019.  The contest submissions must be created using ArcGIS StoryMaps, not classic ESRI Story Maps apps.

The 2019 contest will work differently than contests in years past. To up the ante, ESRI added a monetary prize and community element.  When participants submit their entries, they will also describe how they would use a $5,000 donation from ESRI to make a positive impact on their communities through storytelling.

The winners will be announced by ESRI president Jack Dangermond on November 13, 2019, which is GIS Day.  Good Luck!

The Transcontinental Railroad

150 years ago the completion of the transcontinental railroad on May 10, 1869 marked an important milestone in the history of the United States with the joining of the populated east with the growing cities and towns of the west. Stanford University, with its connection to Leland Stanford and Timothy Hopkins, holds in its libraries an impressive array of materials related to this monumental achievement including the often overlooked contributions of the Chinese railroad workers. A new Spotlight exhibit, Transcontinental Railroad, pulls together this material to give an overview of the people and places that played a role in transforming the west.  There are maps too!  Check it out.
