Activity Summary for past 24 hours
- No molten lava visible at Kilauea volcano surface
- DI deflation continues
- Lava lake crusted over very deep within the summit vent
- Summit seismicity slightly elevated
- SO2 emissions and ERZ seismicity are low at summit and East Rift ZoneS
- Sulfur dioxide emission rate about 200 tons per day ((preliminary reading on March 22, 2011)
[NOTE: DI stands for ‘deflation-inflation’ and denotes a volcanic event of uncertain significance.]

“In the image—which depicts mostly infrared wavelengths of light—vegetation is green, older lava flows are brown to black, and “hot” areas are red. In this case, the scorched land and fresh lava in the burn scar appears slightly red and brown, while the still-burning forest fire appears bright red. In the 2010 image, lava stands out within and near Pu’u ‘O’o.” Source: NASA-EO.
On March 5, 2011, a new fissure appeared on Kilauea, the world’s most active volcano. Fresh lava from Kamoamoa fissure spewed to a height of about 50 meters above ground, setting off a forest fire which has since consumed about 2,000 acres.
Kamoamoa fissure is located about 13km east of the volcano summit, lying along the rift zone between Pu’u ‘O’o and Napau Crater .
The above false-color images of of the are were taken by ALI on the NASA’s EO-1 satellite captureda (top) on March 18, 2011, bottom on 16, 2010 (included for comparison).
Kilauea’s latest episode of ongoing activity began in 1983.
