This spreadsheet contains links to all static and streaming volcano webcams that I know of. It will be curated according to the same schedule as my Google Earth KMZ file.
Rows highlighted in BLUE represent either webcams that are new, or webcams that are returning to service after more than 6 months offline.
Rows highlighted in RED represent cameras that have been offline for more than 10 consecutive days.
This sheet includes links to tremor and quakes based on seismic station codes. Some links may lead to instruments that are offline. Such is the nature of being "on shaky ground". This sheet isn't on a regular curation schedule and is most likely to get updated when a new eruption begins.
Alaska Volcano Observatory seismographs each display a 24 hour period. Each instrument has today's 24 hour record, yesterday's 24 hour record, and the 24 hour record from two days ago. Also the location listed is the nearest associated volcano, though not all of these seismographs are currently published on the AVO website. I will try to curate this list at least quarterly.
