Software

USGS Processing Routines in IDL for Spectroscopic Meausres (PRISM) software provides a framework to conduct spectroscopy analysis of measurements made by spectrometers. PRISM functions allows users to compare spectra of materials of unknown composition with reference spectra of known materials.

FLASH (Flow-Log Analysis of Single Holes) is a computer program for the analysis of borehole vertical flow logs.

Conduit Flow Process (CFP) allows simulation of laminar and turbulent flow within a standard MODFLOW layer and/or simulation of a hybrid model (one-dimensional pipe network coupled to MODFLOW).

@USGSted (USGS Twitter Earthquake Dispatch) distributes Twitter alerts for earthquakes worldwide with magnitudes of 5.5 and above. When citizens feel shaking activity, they often use the popular social media application, Twitter, to "tweet" what they are experiencing.

This web application can be used to calculate risk-targeted ground motion values in accordance with “Method 2” of 2010 ASCE 7 Standard Section 21.2.1.2.

Overview The highway-runoff database (HRDB) was developed to serve as a data warehouse for current and future highway-runoff data sets. The database can be used by transportation agencies and researchers as a data warehouse to document information about a data set, monitoring site(s), highway-runoff data (including precipitation, runoff, and event mean concentrations).
