Latest Data

The table below lists all monitored volcanoes. 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.
