Iran’s Capital City Is Being Devoured by Sinkholes

Sinkholes and fissures are opening up the earth around Tehran, Iran’s capital city. And they threaten people’s homes and the local infrastructure.

The ground is cracking open, thanks to a water crisis that has deepened as Tehran’s population has ballooned. The region is in the midst of a three-decade-long drought and ongoing desertification. The problem has been compounded as the city’s population has grown to close to 8.5 million.

Water pumped from underground aquifers has gotten saltier every year as the city has increasingly relied on these underground water sources as opposed to rainwater. At the same time, a great deal of the dwindling water supply gets diverted to thirsty and inefficient agriculture.

As a result, land in the area is physically slumping in on itself. The ground around Tehran, sitting 3,900 feet (1,200 meters) above sea level, has subsided an average of 8.6 inches (22 centimeters) per year based on satellite measurements.

All that subsidence has cracked buildings and water pipes, opened holes in the drying earth, and caused miles-long fissures. Residents fear their buildings collapsing, Nature reported. The airport, oil refinery, highways and railroads in the area are all threatened.

Global Warming

Arctic Ice Retreat Creates Giant Swells For The First Time

The Beaufort Sea in Arctic Ocean is usually frozen. The water is covered with ice most of the time. But researchers have recorded giant waves, as high as 16 feet, just north of Alaska. Swells of that size have stunned the scientists because they have the potential to break up Arctic ice much faster than expected. The North is changing, and it’s changing fast as the sea ice retreats due to global warming.

Jim Thomson of the University of Washington recorded the wave measurements with the help of sensors. The house-size waves were measured during a September 2012 storm. Thomson told The Washington Post that 16 feet swells were the average. The biggest single wave was about 29 feet.

Until recently, the Arctic Ocean remained ice-covered throughout the summer, so there were no waves to measure. But the area of open water is increasing. Thomson said the Arctic ice never retreated more than 100 miles during summer in the past. But in 2012, it retreated well over 1,000 miles. The expanded ice retreat leaves much of the Beaufort Sea ice-free by the end of summer.

Another Massive Hole Appears in Siberia

It’s uncertain yet what’s caused the sinkholes, but experts said global warming may play a part, when permafrost melts, gas is released, causing an underground explosion.

Typhoon Utor is located approximately 236 nm south-southeastward of Hong Kong. Utor is expected to move inland near Zhanjiang, China. Intensification is expected as upper-level diffluence remains favourable. Additionally, the chance remains for the system to intensify more than currently forecast pending interaction with an upper-level low analyzed over southern China.

Sinkhole Opens Under Florida Resort

A resort complex in Florida has partially fallen into a sinkhole, the latest such incident in the state.

All 105 people staying at the Summer Bay Resort in Clermont, near Disney World, were safely evacuated when the ground gave way on Sunday night.

By Monday morning, nearly a third of the complex had collapsed into a sinkhole up to 100ft (30m) in diameter.

Much of Florida straddles a system of limestone caverns that are subject to water erosion, causing them to cave in.

In March, a sinkhole beneath a house in the suburbs of Tampa, swallowed a man who was in his bed. His body was never recovered.
