1994 Volcanic Activity in Alaska: Summary of Events and Response of the Alaska Volcano Observatory [open pdf - 2MB]
"During 1994, the Alaska Volcano Observatory (AVO) responded to eruptions, possible eruptions, or false alarms at nine volcanic centers--Mount Sanford, Iliamna, the Katmai group, Kupreanof, Mount Veniaminof, Shishaldin, Makushin, Mount Cleveland and Kanaga (table 1). Of these volcanoes, AVO has a real time, continuously recording seismic network only at Iliamna, which is located in the Cook Inlet area of south-central Alaska (fig. 1). AVO has dialup access to seismic data from a 5-station network in the general region of the Katmai group of volcanoes. The remaining unmonitored volcanoes are located in sparsely populated areas of the Wrangell Mountains, the Alaska Peninsula, and the Aleutian Islands (fig. 1). For these volcanoes, the AVO monitoring program relies chiefly on receipt of pilot reports, observations of local residents and analysis of satellite imagery. This report presents a summary of volcanic activity in Alaska during 1994 and documents the AVO response. In this compilation, only those reports or inquiries which resulted in a 'significant' investment of staff time and energy (here defined as an hour or more for reaction, tracking, and follow-up) are included. Typically, AVO receives many dozens of phone calls throughout the year reporting steaming, unusual cloud sightings, or eruption rumors. Most of these are dealt with very quickly and are not tabulated here as part of the 1994 response record."
