February 26, 2007—After rumbling for weeks, part of a poor Guatemala City neighborhood plummeted some 30 stories into the Earth on Friday.
The reportedly 330-foot-deep (100-meter-deep) sinkhole swallowed about a dozen homes and is so far blamed in the deaths of three people—two teenagers, found floating in torrent of sewage, and their father, who was pulled from the chasm.
Rainstorms and a ruptured sewer main may have caused the sinkhole, officials in Guatemala told the Associated Press. After the collapse, the seemingly bottomless depths gave off tremors, sounds of flowing water, and the scent of sewage.
Sinkholes can occur when underground rocks that can be dissolved by water—such as salt, gypsum, and limestone—are inundated. The removal of groundwater can also leave gaps underground that can lead to sinkholes.
While the cause of the Guatemala City abyss remains uncertain, it's effects are undeniable.
Police established a 500-yard (457-meter) no-go zone around the sinkhole, and nearly a thousand people were forced to evacuate—some perhaps forever.
"Last night a friend had to take my handicapped wife out on motorcycle," 15-year resident Antonio Fuentes, 50, told the Associated Press. "Now I'm leaving for good, never to come back."

It's unclear from the report, as well, if Google will offer cellular versions of the tablet immediately (last year the company released a wi-fi-only version months before debuting a 3G version). It definitely will be a major threat to Kindle Fire. You've got a dual core 1 GHz Tegra 2 processor, 1 GB of RAM,
a 4 inch touch screen display with a resolution of 950 x 540 pixels
and a 5 MP camera with 720p video capture.
