The exact cause of the crack in the earth still unknown. Peru’s geophysical institute ruled out the occurrence of an earthquake in the region, but what is clear is that the ground opened up and large blocks of earth can be observed scattered throughout the area.
The event, recorded Wednesday morning, caused the collapse of one house located in the rural community of Llorohoco. Four people managed to escape, but the youngest in the family, five-year-old Jean Carlos Vilcanqui Acero, is missing.
Geological engineers from the regional committee for civil defense have arrived in the area to investigate the phenomenon and determine its causes, said Javier Pampamallco, Puno’s civil defense chief.

Humongous sinkhole opens up in Germany
A giant sinkhole opened up in a residential area of the town of Schmalkalden, Germany, Monday, causing no injuries but forcing the evacuation of 25 people.
Firemen secure the perimeter of a sinkhole that has left a huge crater in the middle of a residential area in Schmalkalden, Germany, Monday.

The circular hole, which is about 98 feet across and 65 feet deep, appeared at around 3a.m. in a residential area, reports Der Spiegel, forcing the evacuation of 25 people. Experts are pointing to natural causes for the hole, but they have yet to determine the exact cause.
Sinkholes are often caused by the underground erosion of salt beds or soluble sedimentary rocks, such as limestone or dolomite. Groundwater flows through these rocks, creating subterranean caverns that can suddenly collapse.
In the past year, large sinkholes have appeared in Guatemala City, Tampa, Fla., Quebec, andMilwaukee, Wisc.
Officials from Schmalkalden, a town of 20,000 that was formerly part of East Germany say that they plan to fill the hole with gravel.

Giant crack in Africa formed in just days
- 22:17 04 November 2009 by MacGregor Campbell
A crack in the Earth's crust – which could be the forerunner to a new ocean – ripped open in just days in 2005, a new study suggests. The opening, located in the Afar region of Ethiopia, presents a unique opportunity for geologists to study how mid-ocean ridges form.
The crack is the surface component of a continental rift
forming as the Arabian and African plates drift away from one another. It began to open up in September 2005, when a volcano at the northern end of the rift, called Dabbahu, erupted.
forming as the Arabian and African plates drift away from one another. It began to open up in September 2005, when a volcano at the northern end of the rift, called Dabbahu, erupted.The magma inside the volcano did not reach the surface and erupt as a fountain of lava – instead, it was diverted into the continental rift underground. The magma cooled into a wedge-shaped "dike" that was then uplifted, rupturing the surface and creating a 500-metre-long, 60-metre-deep crack.
Using sensor data collected by universities in the region, researchers led by Atalay Ayele of Addis Ababa University in Ethiopia reconstructed the sequence of seismic events that led to the crack's formation. They found that a 60-kilometre-long, 8-metre-wide dike of solidified magma formed in the rift, causing the crack, in a matter of days.
