Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Nyiragongo Unrest

Plume from Nyiragongo

Nyiragongo Volcano in the Democratic Republic of the Congo released a small plume on June 27, 2009, as the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite passed overhead.

NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) sensors detected hotspots on six different occasions between April 10 and May 4, 2009.  The plume observed by ALI in late June may be a continuation of the low-level activity.

Nyiragongo is a stratovolcano—a steep-sloped structure made of alternating layers of solidified ash, hardened lava, and rocks released by previous eruptions. In contrast to the low profile of neighboring Nyamuragira, Nyiragongo rises to a height of 3,470 meters (11,384 feet) above sea level. Lava flows from Nyiragongo caused substantial casualties in 1977 and 2002.  NASA image created by Jesse Allen, using EO-1 ALI data provided courtesy of the NASA EO-1 Team. Caption by Michon Scott.
