Droughts and Volcanic eruptions are both reflected in the tree rings of Guatemala. Read a series of blog posts by Kevin Anchukaitis, an assistant research professor at the Lamont-Doherty Earth Observatory at Columbia University.
LiveScience has an interesting article on the forms of life encountered around a deep-sea vent system at the boundary of the Cocos and Caribbean Plates off the west coast of Costa Rica.
“A University of Colorado Boulder-led team excavating a Maya village in El Salvador buried by a volcanic eruption 1,400 years ago has unexpectedly hit an ancient white road that appears to lead to and from the town, which was frozen in time by a blanket of ash.” Quoted from the University of Colorado at Boulder news release.
“We now know that fluids from deeper parts of the subduction zone system have percolated up through the layers of sediment. Studying the composition and volume of these fluids, as well as how they have moved through the sediment, helps us better understand the relationship between the chemical, thermal and mass transfer activity in the seafloor and the earthquake-generating, or seismogenic, region of the plate boundary.” Quoted from the National Science Foundation press release.
Jessica Ball has been reporting on an International Volcano Monitoring Fund project at Santiaguito Volcano in Guatemala. See her posts from June 29, July 1 and July 4.
“A NASA-led research team has used a variety of NASA satellite data to create the most precise map ever produced depicting the amount and location of carbon stored in Earth’s tropical forests.” Quoted from the NASA news release.
Telica Volcano in Nicaragua has been erupting with small explosions and an ash plume that reached an elevation of about 3000 feet. Nearby residents and about 500 workers at a geothermal plant near the volcano were evacuated.
“To gauge the long-term effects of a prolonged tropical storm in the Panama Canal watershed in 2010, [researchers] organized four over-flights of the watershed to create a digital map of landslide scars.” Quoted from the Smithsonian Tropical Research Institute press release.
Archaeologists have discovered a battery of cannons in sediments at the mouth of the Chagres River. They are thought to be from one of pirate Captain Henry Morgan’s ships that wrecked en route to a raid on a town that is now known as Panama City in 1671.
Most of Nicaragua’s power is currently generated by burning fossil fuels, however, their San Jacinto geothermal plant is being enlarged from 10 MW to 72 MW.
