Blogging on EARTH

As you would expect, there's been tons of coverage of the earthquake off the coast of Chile and the resulting tsunami in the mainstream media. And some of it has been notoriously poor.

Chile's quake larger but less destructive than Haiti's

On Feb. 27, at 3:34 a.m. local time, a magnitude-8.8 earthquake struck offshore Maule, Chile, 325 kilometers southwest of the capital, Santiago. The quake released 500 times more energy than the magnitude-7.0 earthquake that hit Haiti on Jan. 12, according to the U.S.

Voices: Should science dictate whether to rebuild after a natural disaster?

Move Port-au-Prince? Maybe. San Francisco and New Orleans? Never.

It is common for scientists to call for the relocation of a city to a safer location after it is struck by an earthquake or hurricane. After all, when many cities were built, the nature of the hazard they faced was either unknown or very poorly understood. This is true whether we’re talking about San Francisco, Calif., New Orleans, La., or Port-au-Prince, Haiti. Now that we know the hazards, is it time to relocate a city in a dangerous locale? Port-au-Prince? Yes. San Francisco and New Orleans? No.

Can snowstorms be categorized like hurricanes or other hazards?

On Dec. 18, 2009, a winter storm deposited two feet of snow in a swath from the North Carolina mountains to Baltimore, Md., shutting down airports for days. Eight days later, a Christmas blizzard ripped through the Midwest, stranding holiday travelers in Nebraska and the Dakotas under almost a foot of snow. But which storm was worse? It’s a difficult call to make, because unlike other natural disasters, snowstorms have no categorization system. But researchers at NOAA are changing that: They are creating a unique ranking system to show how winter storms impact society.

Haitian quake no shock to geologists

Although the magnitude-7.0 earthquake that shook Haiti on Jan. 12 was a horrible shock for millions of people in and around the Haitian capital of Port-au-Prince, the event came as no surprise to geologists. For years, scientists familiar with the geology of the region had been warning that the island of Hispaniola, which Haiti shares with the Dominican Republic, was overdue for a major quake.

Extinction-era coal linked to Chinese cancer epidemic

At the close of the Permian, 252 million years ago, conditions on Earth took a turn for the worse, nearly wiping out life on land and at sea in the planet’s most severe extinction event. Now, eons later, geologists are implicating a coal seam that dates to the “Great Dying” at the Permian-Triassic boundary in one of the modern world’s worst cancer epidemics.
