Causes of the formation of ground holes in Guatemala 5

It may be that the crustal rock layer itself in this area is relatively weak and not thick enough, coupled with the serious groundwater exploitation in recent years, the original groundwater has been evacuated, forming a huge underground cavity, the underground is close to a vacuum, there is a huge pressure difference between the surface and the underground, the atmospheric pressure formed by tropical storms increases the pressure difference, coupled with precipitation and gravity, the three together lead to ground subsidence.

In fact, the problem of ground subsidence also exists in China, especially in areas where the earth's crust is weak and groundwater is seriously overexploited, in China, in some places, the groundwater level has dropped by more than 100 meters, forming a huge underground cavity, and a slight external force in such a place is easy to cause ground subsidence.

I don't think a tropical storm can make such a hole.

Attentive people will find out:

1. There are no debris fragments around the ground movement.

If it was really a hurricane. The power should be from the bottom up, and why there are no debris or debris from the collapsed area around the cavern, so it can be inferred that the source of power is from the center of the earth and not from the surface.

2. The cave wall is regular and round. The possibility of surface collapse caused by the pressure difference between the inside and outside of the formation is ruled out.

3. He is in the shape of a trumpet from the center of the earth like the ground.

Once again, it is proved that the power comes from the center of the earth and that the power is strong, and this layer of the earth's crust is directly inhaled.

If I'm not mistaken, if I think of this ground as a cone, then finding the cone at the very top of the cone will give you the answer.

It's just that this power is too sensational, and I hope that scientists can give us more correct answers through field investigations.

Tropical storms have more rain and greater groundwater flows, which will first wash away small soil particles to form larger channels, and then large soil particles to form many channels in the soil. This is called pipe surge, which is a kind of disaster in geotechnical engineering.

Many scholars in the world study Mayan culture, and the more recognized historical periodization of Mayan civilization is: from 1500 BC to 317 AD is the pre-classical period of the development of Mayan civilization, from 317 AD to 889 AD is the classical period, and from 889 AD to 1697 AD is the post-classical period. It is also referred to as the early, middle, and late stages.

Pre-classical civilizations emerged in Guatemala's Pacific coast and highlands. At this time, the main feature of the Mayan culture was the erection of many large stone monuments in the city squares that appeared, carved with images of the rulers of the past dynasties. Because hieroglyphs appeared in the 1st and 2th centuries AD, the stele contains a text describing the history of the ruler.

In addition, large stone structures (such as pyramids and the city's acropolis) appeared in the city. The large stone-paved plazas and causeways reflect the scale and level of architecture at this time. The centers of civilization in the pre-classical period were Nakbe and Elmirador in Central America.

During the classical period, the center of civilization was in the regions of Tikal, Palenque, Bonampak and Copán in Guatemala. The cultural characteristics of this time are mainly reflected in architecture, sculpture and painting. Bonampak murals are a world-famous treasure trove of art.

The center of the Mayan classical civilization in Mesoamerica declined for unknown reasons in the 9th century. After that, the Mayan culture moved north to the Yucatan Peninsula in the United Mexican States, where it entered the post-classical civilization period. The post-classical Mayan civilization had three major centers: Chichenitza, Uxmal, and Mayapan.

I think this should be similar to the principle of the Great Blue Hole in Belize.

The greatest blue hole is the largest underwater cave in the world, located about 60 miles (km) off the coast of Belize, near Lighthouse Reef, at N17 degrees 18 minutes 54 seconds and W87 degrees 32 minutes 6 seconds. The appearance of the Great Blue Grotto is round, and the Great Blue Grotto of Belize is round

The Great Blue Grotto, Belize.

It is about 1,000 feet (304 meters) in diameter and 400 feet (122 meters) deep. The Great Blue Cave is a limestone cave that was formed during the ice age when the sea level was low, and later became an underwater cave when the roof of the cave collapsed due to the rise of the sea.

Today, the Great Blue Grotto is a well-known diving destination, and the world-renowned scuba diving expert Jacques-Yves Cousteau named the Great Blue Grotto as one of the top 10 diving gems in the world, and in 1971 it was surveyed.

Causes of formation. It is a limestone crater formed at the end of the Ice Age. Located on the Lighthouse Reef on the edge of the submarine plateau in Grand Bahama Shoal, the Belize Blue Grotto is a perfectly rounded hole surrounded by two coral reefs.

The cause of its cause has been revealed by scientists after countless field investigations and analyses. The Bahamas is a calcareous platform that was formed 130 million years ago. During the Ice Age, two million years ago, a cold climate froze water in the Earth's ice caps and glaciers, causing sea levels to drop dramatically.

Due to the erosion of fresh water and seawater, many karst cavities have formed in this calcareous area. The location of the Blue Cave was also a huge rock cave, and the porous and loose limestone dome coincidentally collapsed into a near-perfect circular opening due to gravity and **, becoming an open shaft. When the snow melts and the sea level rises, seawater backs up into the shaft, creating a strange blue hole phenomenon embedded in the sea.

The big cave in Guatemala must have been there very early, forming a vacuum in the ground, due to the low pressure formed by the tropical storm forming a suction force that sucked the ground up, because of the existence of the big hole, the ground on the top of the cave was thinned, and the roof of the cave was revealed, so I saw this hole.

Heavy rain caused by Tropical Storm Agatha. As a result, a huge deep pit appeared in the city of Guatemala. Guatemalan sinkhole, which is a huge deep crater formed by the continuous erosion of solid rock layers by water, causing the surface of the earth to collapse.

It was formed by the collapse of the ground, which is made up of volcanic pumice stones such as gravel, hundreds of feet thick, and is not solid, which is caused by the continuous impact of the water.

The world-famous Guatemalan sinkhole, which is affected by the torrential rain caused by tropical storm "Agatha", a huge crater about 100 meters deep appeared in the Guatemalan capital Guatemala City area.

The scientific explanation is that the continuous erosion of water on the solid bedrock causes the surface to collapse and form a huge deep pit.

It is a huge pit formed by the continuous erosion of solid bedrock by water, causing the surface to collapse.

The world-famous sinkhole in Guatemala is a large crater formed by an asteroid hitting the earth, and this crater has formed its own unique environmental chain, which may be different from some ecological environments outside, and their scenery is very beautiful.

On May 31, 2010 local time, affected by Hurricane "Agatha", a 60-meter-deep collapse hole appeared in Guatemala City, the capital of Guatemala, and there were witnesses that a three-story building fell into the hole, killing at least one person. Local residents say the ground has collapsed due to heavy rains and defective drainage facilities.

This year, Agatha, the first tropical storm in the Pacific Ocean, swept through several countries in Central America, bringing continuous torrential rains, landslides and severe flooding, which has killed at least 145 people, left thousands homeless and forced more than 100,000 people to be relocated.

At least 120 people have been killed and 53 are missing in the worst-hit Guatemala, where rescuers are rushing to remote mountainous areas that have been badly washed away by floods and collapsed bridges, said Eric, a spokesman for Guatemala.

More than 110,000 people in Guatemala have been forcibly relocated, and thousands have fled to neighbouring Honduras. According to Mauricio Funes, El Salvador, 10,000 people have been evacuated in the country, the death toll has risen to 10 and two are missing. The country's transport minister, Jason, said that 95 percent of roads were affected by floods and landslides, 179 bridges were damaged, and traffic was severely blocked.
