Graphical abstract of the new research paper. The scientists collect samples from the rocks forming near hot springs and geysers. They dissolve small amounts of the rock in acid and organic carbon (created by living organisms) remains behind.

Earthquake-triggered landslide on south coast of Haiti near village of Nan Diamant.

Boulders of intact limestone that fell and rolled during the earthquake from cliffs along the Haiti earthquake fault zone.

This photo shows the dense concentration of landslides in limestone near the Haiti earthquake fault zone.

Flooded gaging station on the Souris River near Westhope, North Dakota, April 20, 2011.  See other pictures in this gallery with the tag 05124000 to see what the gage house normally looks like - it is on a raised platform on the bank of the river with an access road next to it.

Would you know there is a boat ramp here?  Launching a boat during high water on the muddy Missouri River requires intimate knowledge of boat ramps.  The Glasgow, MO, boat ramp (pictured) is underwater when the local gage is approximately 29 feet. 

Scientist Joe Svetek pauses to record notes in his dump-truck-turned-mobile-office at one of the many seismic shot hole locations of the 2011 Salton Seismic Imaging Project.

Following several collapses and small explosive events that deposited spatter on the floor of Halema'uma'u crater around noon, the lava surface in Halema'uma'u was roiling and agitated for the remainder of the afternoon, with numerous points of upwelling and spattering.

A USGS student employee and sophomore at the Colorado School of Mines, was among the first hired by USGS using Recovery Act funding to upgrade the seismic stations of the Advanced National Seismic System (ANSS) Backbone.

Tributary to Snake Creek, near Whitesburg, Georgia, showing a washed out bridge. When bridges such as this one collapse during a flood, it is rarely the pressure of the rushing water against the bridge that causes the bridge to fail.
