Volcanoes of the North Pacific and the Mariannas of interest to the Alaska Volcano Observatory.
A listing of archived data from previous days is available here.
The table below lists all monitored volcanoes. Every minute the distance is calculated from each volcano to each lightning flash detected by WWLLN over the previous hour. For each volcano, the total number of flashes detected within both an inner 20 km radius and outer 100km radius are determined and shown in the table. To view the detected lightning flashes, use Google Earth to open the corresponding KML file for that volcano.
