Thanks to NASA’s Earth Observatory for this informative graphic and text on the Haiti quake:

“At 4:53 p.m. local time on January 12, 2010, a 7.0-magnitude earthquake struck Hispaniola Island, just 10 miles southwest of the Haitian capital of Port-au-Prince. Besides its strong magnitude, the earthquake’s shallow depth of roughly 5.2 miles ensured that the densely populated capital suffered violent shaking.

“This map shows the topography and tectonic influences in the region of the earthquake. Lighter colors indicate higher elevation. Black circles mark earthquake locations determined by the U.S. Geological Survey, and circle sizes correspond with quake magnitudes. Dozens of aftershocks followed the main quake. Red lines indicate fault lines.

“The epicenter of the quake appears just south of the Enriquillo-Plaintain Garden Fault, the southernmost of two major east-west-trending faults that bear the stress of the convergence of the Caribbean and North America tectonic plates in this location. Though faults are weak spots or fractures in the Earth’s crust below the surface, very often there are topographical clues to their presence. In this case, the presence of the fault is indicated by long, straight valley cutting through southern Haiti, just south of Port-Au-Prince. The Enriquillo-Plaintain Garden Fault is a strike-slip type fault, with the Caribbean plate moving eastward with respect to the North America plate.”

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
