What is the satellite based method to record volcanoes
InSAR which ,measures changes in the shape of the earth surface so magma movement can be observed
How can volcanoes ‘vitals’ be recorded
Bytaking gas measurements and monitoring seismic activity, changes in these my suggest magma is rising

Infrastructure investments in Ethiopia
Part of the belt and road initiative, hawassa industrial park expected to employ 100,000 locals.
What is being planned at corbetti
A geothermal plant, which has an expected energy yield of 10,000 MW
What has helped in Kenya
A geothermal plant which has meant that electricity has rises from 20% in 2019 to 60% of the population having electricity
What do the volcanoes also allow
Leisure and tourism via spas and resorts
