Sanborn maps of Nevada

Sanborn maps of Nevada

The University of Nevada, Reno (UNR), as part of its Nevada in Maps collection, has made Sanborn maps of 29 Nevada towns available online for free. The dates of the maps range from 1879 through 1923. From the site: "Nevada's early western settlement history was one of tenuous existence. Settlements, hardly towns much less cities, came and went usually as mining sites were exploited and declined. Few maps exist to document the existence and changes to these towns . . . This project is an effort to present online a full-color set of Nevada SanbornŽ and other Nevada town maps. There is no full set in any format available at any location in the state."

The site also features a very useful set of links that include information about Sanborn maps, information about the UNR map project, an inventory of various formats of Nevada town maps online, and a site that details the coordination between Sanborn maps and historic photographs of specific buildings in Nevada.

Recent earthquakes in California

Recent Earth quakes in California and Nevada 1/30/09

There hasn't been an earthquake around the Bay Area for awhile, right? Well, not really.

The USGS makes up-to-the-hour earthquake information for California and Nevada available as part of their Real-Time Earthquake Maps site. From the site's FAQ: "[The site] currently combines data from the Northern and Southern California and Nevada seismograph networks and will expand to include others. It is mirrored on multiple sites for robust service during earthquake sequences and network problems. It offers complete coverage with no gaps because of an overlapping system of maps. It provides text information on each earthquake and auxiliary information on some of them."

Other maps from this program include shake maps for northern and southern California, and special maps for Long Valley, Los Angeles, San Francisco, and Parkfield.

A great resource for local and international earthquake information can be found on the Berkeley Seismological Laboratory site. This site features a robust collection of earthquake information including: felt reports, CISN earthquake reports, earthquake maps and lists, and seismocams, and a blog, among other resources.
