Study looks at causes of glacial earthquakes
When huge ice chunks break away from a glacier and fall into the ocean, the force pushes the glacier backward,
resulting in glacial earthquakes, according to research published in ScienceXpress. "It's like taking a really strong spring,
pushing on the front of it and just making it compress," said Meredith Nettles, who is studying glacial quakes in
Greenland. Researchers say glacial quakes may become more common as global temperatures rise. LiveScience.com

China may relocate Beijing's municipal offices
China is reportedly planning to move municipal government offices in Beijing to a nearby town called Tongzhou to ease
congestion and support the creation of a new urban cluster in the area. "The move is ironic, given that earlier planners
advocated something similar in the 1950s," said Thomas Hahn, a geographer and historian affiliated with the University
of California at Berkeley. The New York Times (tiered subscription model) (6/25)

All of Earth's giant craters have been counted, study suggests
All the big surface impact craters on Earth have been found, so researchers should focus on locating about 350 smaller
ones, according to geophysicists at Germany's University of Freiburg. The study, set for publication in Earth and
Planetary Science Letters, looks at asteroid impact rate estimates combined with erosion rates. ScienceMag.org (6/26)

Study finds racial neighborhood disparities across incomes
Across the economic spectrum, whites tend to live in higher-income neighborhoods relative to blacks and Hispanics,
according to a Stanford Graduate School of Education study. For example, a black household earning $50,000 annually
on average lives in a neighborhood with median income below $43,000, while a white household with the same annual
income lives in a neighborhood where median income is nearly $53,000. The patterns of segregation have long-term
consequences, researchers say. The Washington Post (tiered subscription model) (6/24)

Humans to blame for latest mass extinction, study says
The Earth is experiencing a mass extinction event, and mankind is to blame, a study says.
Mammalian species are dying off at up to 100 times the usual rate, the study found. "The
smoking gun in these extinctions is very obvious, and it's in our hands," said study co-author
Todd Palmer. The Washington Post (tiered subscription model) (6/22)

Using a supercomputer to improve flood maps
A company called Katrisk is using the Titan supercomputer at Oak Ridge National Laboratory to create more detailed
flood-hazard maps that could help insurance companies price policies. The Federal Emergency Management Agency
already puts out its own flood maps, but Katrisk co-founder Dag Lohmann says they don't provide enough information
about flood severity. "You don't know whether the flood is 2 inches high, 2 feet high or 2 meters high," he said. National
