The largest cities of the United States, mainly, the weight of groundwater, geological processes and buildings, the weight of the Columbia Climbia climbia is in different degrees.
Research authors are used this week using satellite data to analyze the vertical movements of the earth this week.
28 of the country, 25 out of town, two-thirds or more surfaces or more surfaces, a statement released by Colombian Climate School. “In general, 34 million people live in the affected areas.”
The faster sinking city, Texas, Texas Houston. The other two locations of this state – Fort Worth and Dallas – not behind. Highlighting the areas of New York, Las Vegas, Washington DC and San Francisco.
Researchers said “Underground water production for human use, 80% of the total batman was the cause of the insect,” said the problem of oil and gas. “
“We will see that when the cities continue to grow, we will see that more expanding to the sinking areas,” said the researcher at the researcher Columbia Climate School in Leonard Ohenenh, Lamont-Doherty Observatory.
The research ends the results of some cities that some cities have sunk to different rhythms or have lost height in some of them, and in others. According to researchers, the continuous population should be more worse with growth and water use and drought.
In some areas, natural forces help this phenomenon. The gravity of buildings can also charge the price.
The study detects another basis of the basis: some cities have uneven in neighboring places. This can occur because they sank to different rhythms or an increase in the area and a descent in the other.
This “differential movement is a problem, because the whole city area is equal to equal or low, minimizes the risk of tension for buildings and other infrastructure,” he said. If the actions are unevenly, “a dangerous inclination can live.”
According to the research, only 1% of the total surface of the city “can affect the differential movement to buildings, roads, railways and other structures.” But it tends to be in tight city cores. Contains 29,000 buildings right now.
