Volcano Watch – What does the Volcano Alert Level and Activation Color Code mean?
The US Geological Survey Hawaiian Volcano Observatory sets the Volcano Alert Level and Aviation Color Code for volcanoes in Hawaiʻi and American Samoa. Currently, Kīlauea is erupting and is at WATCH/ORANGE, Mauna Loa is in elevated unrest and is at ADVISORY/YELLOW, and the remaining six monitored volcanoes are at NORMAL/GREEN.
Volcano Watch: Remembering Mauna Loa’s Eruption on July 5-6, 1975
Mauna Loa erupted forty-six years ago this week, on July 5–6, 1975, in a 20-hour event with vents confined to the summit region (the area above 3,660 m/12,000 ft) and lava flows descending to just below 3,170 m (10,400 ft). This was the first eruption in 25 years, at the time the longest quiet stretch since 1843 (we are currently in the longest stretch at 37 years and counting).
