Sinkhole in Guatemala

Guatemala City sinkhole

A huge sinkhole in Guatemala City, Guatemala, crashed into being on Sunday, reportedly swallowing a three-story building and echoing a similar 2007 sinkhole also in Guatemala. The sinkhole has likely been weeks or even years in the making - floodwaters from tropical storm Agatha caused the sinkhole to finally collapse, scientists say. The sinkhole appears to be about 60 feet (18 meters) wide and about 30 stories deep.

Scientists measure Earth's history

I do think a lot about how inconsequential humans are in the big scheme of things. We have not yet even proved we're a viable species compared to dinosaurs, for example. Dinosaurs were around from 230 million years ago to 66 million years ago. That's a long time. They were very successful. Humans have been around for maybe a million years. It doesn't look like we're going to have that long of a legacy but we'll see.

(professor of geology at MIT's Department of Earth, Atmospheric and Planetary Sciences)

I have been thinking and saying that for years but this is the first time I see it written by somebody else, by a MIT's professor of Geology not some other opinionated dude like me. I also always use dinosaurs as a comparison..

EARTHTIME is an organized, community-based international scientific initiative aimed at sequencing Earth history through the integration of high-precision geochronology and quantitative chronostratigraphy. Our main goal is the development of the geochronological techniques necessary to produce temporal constraints with uncertainties approaching 0.1 percent of the radioisotopic ages.
