Webicorders for each station are available using the MetaData Aggregator, for example for station RED, here is a sample webicorder plot for channel EHZ: RED.AV..EHZ

For station NCT, channel EHZ here is a sample: NCT.AV..EHZ

Mt Redoubt is close to Anchorage, so when there is an eruption then it can be a big problem for flight traffic. The volcano requires close monitoring by the USGS. Redoubt Volcano Eruption Information.
