Limnic eruptions are a rare, but potentially deadly class of natural disaster, in which toxic gases are rapidly expelled from a saturated lake.he resulting cloud killed 37 people who were living near the lake. At Lake Nyos, in 1986, a similar disaster occurred, in this case killing between 1,700 and 1,800 people, and uncounted numbers of livestock and other animals.
The other bone in the lower leg is the fibula, to which the hamstring, soleus and peroneus muscles attach. Like the tibia, the fibula is also an attachment site for the muscles that flex and extend the foot. The femur, the bone in the upper leg, is the attachment site for numerous muscles.
All three begin at one common tendon attached to the ischial tuberosity of the pelvis (sit bones). The semimembranosus and semitendinosus connect to the tibia on the inside of the leg, and the biceps femoris connects to the top of the fibula on the outside of the leg. These muscles flex, or bend, the knee.his tendon continues below the patella to connect to the tibia. These muscles extend, or straighten, the knee. The hamstrings are the muscles on the back of the thigh. This muscle group is composed of the biceps femoris (outside), the semimembranosus, and the semitendinosus (inside).
