Q

Introduction- Events

A

-On January 17th 2002, after several months of increased seismic and fumarolic activity, the volcano erupted on a large scale.
-A 13km large fissure opened, allowing magma to rise through the volcano and out onto the steep hillsides as voluminous lava flows, where they gathered pace, travelling at up to 40 miles per hour, towards the provincial capital of Goma.
-Lava streamed through the town towards lake Kiyu, prompting fears of contaminants and toxins within the lava irreversibly damaging the ecosystem which the locals wrote so reliant on as a source of income.

Q

Government responses

A

-Notably, the management of the disaster was very poor, little advanced warnings or emergency protocols were in place, and as many LICs, few people were educated on the dangers of toxic gases.
-Many locals had to work themselves to fund reconstruction efforts, as the government was notoriously corrupt, so little aid was actually available.
