Goats can get two kinds of lice: sucking lice and biting lice. Biting lice eat dead skin cells on the goats and make them itch. Sucking lice are more serious â they not only cause itching, but they suck the goats' blood, which can lead to anemia.
South-west China lies in an area that is prone to earthquakes. An earthquake in Sichuan in 2008 killed tens of thousands of people. And in 1970, a magnitude 7.7 quake in Yunnan killed at least 15,000 people.
The Worldâs largest earthquake with an instrumentally documented magnitude occurred on May 22, 1960 near Valdivia, in southern Chile. It was assigned a magnitude of 9.5 by the United States Geological Survey. It is referred to as the Great Chilean Earthquake and the 1960 Valdivia Earthquake. The United States Geological Survey reports this event as the largest earthquake of the 20th Century. Other earthquakes in recorded history may have been larger, however this is the largest earthquake that has occurred since accurate estimates of magnitude became possible in the earnly 1900's.
