The shaking of the earth's crust at any point causes vibrations that are transmitted across the globe. This movement has the effect of inducing in the soil and in the works of rapidly varying inertial forces over time. Its action is exerted essentially dynamic way, but it takes on different aspects in structures, soil. Is recorded structural damage equipment and manpower.
South Kivu province, mainly the city of Bukavu and the neighboring countries were shaken by a violent earthquake, among the rarest recorded in the region, to Sunday 03/02/2008 9:34 local time (7:34 'GMT) . The 6.3 magnitude earthquake on the scale of RICTHER had its epicenter, according to the seismological observatories NSRF / Lwiro, around Birava in the same province, 20 km north of Bukavu, whose home was 33 km deep, according to still the same source (shallow earthquake: less than 60Km). It lasted about 20 seconds. This tectonic phenomenon has generated much of the damage as well geomorphological, material as humans.

The present work proposes the determination of the rainy thermical rhythm in three parts in Luhwindja based on the North, Center and South which has not been known for a long time.
The south area of Luhwindja is better watered to some extent with 1753mm of water a year and the more less hot has got the everage yearly temperature of 17.4 degree centigrade. As the matter of fact three is not any month which is dry and scows can be transcorried the whole year; the monthly "ETP" being inferior to precipitations of all the twelve months of a year.
The North's area of Luhwindja with a yearly rainy thermical of 1553mm the everage temperature is 19.2 degree centigrade. It is the part less watered with three months which are affected by atmospherically drought during (June, July and August) are affected by pedological drougth; the "ETP" being superior to precipitations for the three dry months.
The Center receives on the one hand, precipitations coming from the North and on the other hand those of the South. It realizes 1611mmof water per a year and an everage temperature of 20.5 degree centigrade with three months affectedby atmospherically drought (June, July and August).
On average the whole Collectivity of Luhwindja receives 1639mm of water per year and a temperature of 19, 03 degree centigrade.
