Q

What were the Economic impacts of the eruption?

A

80% of Goma’s infrastructure destroyed e.g. schools, hospitals, homes, power plants

Electricity took 1 month to restore

Acid rain damaged from volcanic gases (sulfur dioxide) damaged crops and harmed cattle limiting agricultural output

However informal sector reappeared within 5 months, establishing stands on lava to sell cigarettes showing community resilience

14 villages obliterated by lava

Many couldn’t afford to rebuild; informal settlements left on dangerous land.

Goma’s economy relies on trade, tourism, and informal jobs, all disrupted
