Kenneth, classified at one stage as a category 4 cyclone, smashed into the northern parts of Mozambique on Thursday evening with wind speeds of up to 280 km/h. 

Cyclone Kenneth has killed at least one person and left a trail of destruction in northern Mozambique, destroying houses, ripping up trees and knocking out power, News24 reported.

Some 30,000 Mozambicans were evacuated in northern parts of the country in preparation of the deluge of rain and impending destruction, reported Al Jazeerra.

Six weeks earlier Cyclone Idai, classified as a category 3 cyclone for reaching wind speeds of between 178 - 209 km/h, devastated the central part of the country as well as parts of Madagascar, Malawi and Zimbabwe, leaving over a thousand dead and an estimated R11 billion in damages to buildings, infrastructure and agriculture, according to the UN. 


Put side by side, satellite images reveal the devastating scope of the cyclones.

In terms of size, cyclone Kenneth is larger than its predecessor, which stretched out for about 700km.


For scale, we also compared it to the land area of Gauteng.
