My First-Hand Experience with the Waldo Canyon Wildfire and GPS

July 10, 2012By

Tuesday, the 26th of June, started off as a beautiful day in Colorado Springs, if you ignored the towering plume of smoke to the west from the Waldo Canyon Wildfire. The wildfire started three days before in the popular Waldo Canyon hiking area in the Rocky Mountains just off Highway 24. While people in the Colorado Springs area were concerned, there were currently eight other wildfires raging in the state of Colorado and over the past month arsonist(s) were suspected of starting up to 20+ wildfires. So many had become inured to the sight and smell of smoke. Only one serious wildfire was known to be currently out of control in Colorado at the time, so concerns in the Colorado Springs community could be described as moderate. Then at 1630, that’s 4:30 P.M. for my non-military readers, the wildfire displayed its true personality. read more

On the Edge: Sensing the Rivers

July 1, 2012By

A fleet of 100 robots equipped with GPS and sensors were released May 9 into California rivers to measure water flow, salinty levels, and pollution. The Floating Sensor Network is a project by the University of California, Berkeley, to improve the way water quality and flows are monitored. About two-thirds of California’s fresh water is in the Sacramento-San Joaquin river system where the test took place. This water supplies about two-thirds of the state’s population with drinking water and irrigation. The initiative is led by associate professor Alexandre Bayen at the Center for Informatin Technology Research in the Interest of Society (CITRIS). read more

On the Edge: Southwest Shakes

March 1, 2012By
Researchers used data from 25 continuous GPS stations installed as part of the EarthScope Rio Grande Rift GPS experiment, supplemented by data from other GPS monuments in the southwestern U.S., resulting in a data set of daily position estimates of 284 GPS monuments for the years 2006 through 2010.

Using a large network of GPS stations, a team of researchers has found that the Rio Valley Rift in the Southwest United States — previously suspected to be dead — is slowly expanding, at a rate of about 0.1 millimeter per year. The Rio Grande Rift extends from Colorado’s central Rocky Mountains to Mexico. read more

On the Edge: Tracking Slips and Creeps: Earthquake Monitoring Gets Substantial Boost from GPS

July 1, 2011By
Arrow on a Velocity Field Map of Oregon and Washington represent ground motion as measured by GPS at each particular location. The grey circles are 2 sigma error ellipses (click to enlarge.)

The Earth’s surface is constantly shifting, being deformed as earthquake faults accumulate strain, and slip or slowly creep over time. Not long ago, scientists relied solely on seismometers to monitor the earth’s movements. Today, GPS has taken prominence as an indispensible tool. PANGA, the monitoring network covering the Pacific Northwest, uses GPS to monitor this movement by measuring the precise position (within 5 millimeters or less) of stations near active faults relative to each other. By determining how the stations have moved, ground deformation can be determined. read more
