Sinkhole swallows California pond overnight

March 21, 2013CALIFORNIA - Overnight, a sinkhole swallowed a pond on Mark Korb’s property in Newcastle, Calif. When he went to bed Saturday night, the pond was there. On Sunday, March 17 it was gone. How does that happen? While northern California is nowhere near as prone to sinkholes as Florida (see USGS sinkhole map), one clue might be the fact that the pond was man-made. While sinkholes don’t need a human trigger; changes in drainage due to construction or agricultural irrigation have been known to activate mass outbreaks of sinkholes in Florida, and other parts of the country. As The Christian Science Monitor reported earlier this month after a Florida man was swallowed in his bed by a sinkhole, “Drought followed by heavy rains can also instigate sinkholes as heavy, water-logged earth presses down on limestone caves suddenly devoid of buoyant water. The two previous deaths attributed to sinkholes both involved professional well drillers whose activities cracked the top of limestone caverns, causing collapse. Humans can [destabilize karst landscapes] by drawing down water tables or irrigate too much, increasing the weight of the mass of materials that sits on top of the void,” says Jonathan Martin, a geologist at the University of Florida, in Gainesville. “Humans can modify the environment” enough to cause sinkholes. The US Geological Society echoes this idea: “Sinkholes can also form when natural water-drainage patterns are changed and new water-diversion systems are developed. Some sinkholes form when the land surface is changed, such as when industrial and runoff-storage ponds are created. The substantial weight of the new material can trigger an underground collapse of supporting material, thus causing a sinkhole.” So, it’s possible that when Korb built his pond, he may have disturbed the local geology. Another theory for the swallowing of Korb’s pond was put forward by Sierra College Professor of Geology Alex Amigo. He also points to a human cause: gold mining. This part of California is dubbed “Gold Country,” for its long history of mining. “There was such a lot of mining activity going on in this area in the past, that we never know when there was a man-made cavity underground,” Amigo told KCRA-TV. Korb is now looking into how to deal with the sinkhole and doing research on the history of his property to see if there has been any gold mining on or near the property in the past. –CS Monitor
Sinkhole closes street in Toronto: CANADA – A large sinkhole about 10 feet deep has closed a section of downtown Toronto Wednesday afternoon. The sinkhole was discovered in front of 364 Adelaide Street between Spadina and Peter. The area has been closed to traffic as a precaution and city crews have been dispatched to investigate the problem. There’s no word yet on when the street will reopen to traffic. –Global Toronto

    • There are underground tunnels which stretch from coast to coast in the US. They are used by government and elite. They are probably adding to the community down there. They know people cannot fathom this possibility so they make as much noise, booms or whatever else they want because the sheeple above are clueless anyway.

    Lake Michigan is at its lowest level ever recorded and according to the Alliance for the Great Lakes, it all depends on climate.

    The alliance says the biggest factors that regulate the level of the highly-prized resource is rainfall and evaporation.

    Last year we experienced severe drought conditions here in the Midwest and other parts of the country and with hot temperatures came even more evaporation.

    What we can expect, says the alliance, is the trend toward more extremes in lake levels and storms.

    Sinkholes in Toronto regularly, some places are 4 stories underground. but with the freeze and thaws, watermains break all the time.

    Check out the photo in this link of the Florida sinkhole of March 2 2013. There is DEFINITELY a curved tunnel of broken bricks on the side of the hole; which means that there was a cavity already there that the local council is not going to tell anybody about. Liability reasons maybe?
