Answer: 10, 100
Explanation:
Magnitudes are based on a logarithmic scale (base 10). For each whole number you go up, the amplitude of the ground motion recorded by a seismograph goes up ten times. Using this scale, a magnitude 5 earthquake would result in ten times the level of ground shaking as a magnitude 4 earthquake (and 32 times as much energy would be released). 
1 unit increase corresponds to 10 fold increase in magnitude.
 
        
             
        
        
        
 
Human environment interaction
In east africa the weather is mainly pleasant. It is usually warm, dry, and sunny. But there are a few different weather patterns that affect it differently. around mid-march to may, there is an especially rainy season were heavy rains occur. This is called masika . There is also a much shorter rainy season called vuli, and it happens during November and December. Right now we are in Vuli, and the heavy rains in South Sudan have caused floods that have killed over 50 people. The storms are getting much worse on account of how unpredictable the waters around East Africa are getting, and around 420,000 have run away from their homes because they are flooding at an alarming rate. And because of dead animals and garbage in the water, it could hold many diseases.
