IceWeb is a web-based near-real-time seismic monitoring system for Alaskan volcanoes that I developed during my AVO postdoc from March 1998 to January 2000, and then overhauled while working for AVO again between November 2008 and September 2012. These two operational versions are very different. A 2013 snapshot of the MATLAB and PhP code is included in the main folder. A snapshot of the the legacy version of the MATLAB and Perl-CGI code from January 2000, along with response data, wind data, and computed reduced displacement data, as well as a snapshot of web server files and log files is included under the legacy_iceweb folder.
