The Guatemala City Sinkhole
Guatemala has big problems with sinkholes that are caused by the country’s numerous volcanos. This is a picture of a sinkhole that opened up on May 30, 2010.
The sinkhole, which took mere seconds to form, is 18 meters (nearly 60 feet) wide and 100 meters (328 feet) deep.
It is also in the middle of Guatemala City. Unfortunately, the sinkhole caused serious damage, including one poor resident’s home being swallowed in addition to a three-story building.
Thor’s Well, America

Thor’s Well, or as some people like to call it, a ‘gate to hell’ is a mysterious sinkhole, which is located in the Cape Perpetua Scenic Area along the coast of Oregon. It seems that no matter how much water goes into the hole it can never be filled up.
This ‘drainpipe of the Pacific’ does present unpredictable dangers, but in 2017 only three incidents were reported. The people involved suffered only cuts and bruises after being hit by waves and pushed against sharp volcanic rock.
