What to know about sinkholes

Sinkhole in Seffner, Florida (AP /ABC Action News-WFTS TV)
A gaping, 16-meter sinkhole that claimed the life of Jeff Bush from Florida, after his bedroom collapsed underground, kept the news headlines around the world. However sinkholes, proved to be something more regular than you believe. This phenomenon for example, is common in Florida. Hereunder a few details about sinkholes:

1. How does a sinkhole take shape? "Cover-collapse" sinkholes emerge when groundwater leads to underground cavities and voids that grow so large the ground above can’t sustain itself. Therefore these holes can feature tremendous sizes enough to swallow a street, home, a field or a swimming pool.

2. What extra types of sinkholes? There are 2 other different kind: "solution" and "subsidence" sinkholes, which emerge due to changes to the topography that happens slowly over time without devastating outcome.

3. Which states have sinkholes? The entire Florida is exposed to sinkholes because of sitting on top of a layer of limestone rock known as karst, which is easily dissolved by acidic groundwater.
U.S. Geological Survey (USGS) claims that other vulnerable states include Tennessee, Alabama, Missouri, Texas, Kentucky and Pennsylvania.

4. Are sinkholes something usual? Hurricanes and quakes are tracked but sinkholes are not.

5. Can people cause sinkholes? The answer is yes. Human activities such as drilling for a well or mining, which lower water levels underground, can trigger sinkholes.

A giant sinkhole reported in Guatemala was created in 2010 most likely by human actions.

Elena Serova
Elena Serova, a Russian female cosmonaut, will be part of a 2014 space mission, an event marking the return of Russian women in the race to conquer space after a break of nearly 20 years.

36-year-old Serova, a member of the professional cosmonauts, "is currently preparing for a space mission that will take place in the second half of 2014," said Aleksei Temerov from the astronaut training center known as the Star City, near Moscow.

Russia celebrates this year the 50th anniversary since the first mission in space carried out by a woman - Soviet Valentina Tere┼čkova- on June 16, 1963.

Elena Serova is set to spend six months aboard the International Space Station, becoming the fourth Russian female cosmonaut remaining in space for a long time, said Temerov.

"The work timetable on the ISS shows nothing extraordinary. It is going to be a regular scientific program. No exit outside the ISS is scheduled," he added.
