Erik Klemetti posts an update on recent activity at Ubinas Volcano in Peru. In addition, some people have expressed concern about the recent magnitude 8.2 earthquake triggering an eruption at one of several nearby volcanos, Erik comments on these concerns plus, in another post, on the recent earthquake at Yellowstone.
A magnitude 8.2 earthquake struck off the Pacific coast of Chile at about 6:46 PM local time. An early report in the Los Angeles Times indicates building and highway damage. A tsunami warning was issued but waves observed were small. View USGS Data.
Did you know that there are seven distinct depressions on Earth that are over 100 meters below sea level, and twenty-three that are over 10 meters below sea level and ten more that are at least two meters below sea level? We have a google map that points to ten of these depressions and a list of the remaining locations.
Researchers monitored over thousands of penguins over nearly three decades to determine their mortality factors. One conclusion is that climate change is causing more frequent and more intense storms that kill many penguins.
The Energy Information Administration recently published their annual Liquid Fuels and Natural Gas in the Americas report. It includes the map below showing the flow of crude oil within the Americas during 2012.
““Iris Agate” is a name used for a finely-banded agate that produces a spectacular display of color when it is cut properly and illuminated from a direction that sends light through its very thin bands.”
“The chance transit of a satellite over the April 2009 eruption of Fernandina volcano — the most active in South America’s famed Galápagos archipelago — has revealed for the first time the mechanism behind the characteristic pattern of eruptive fissures on the island chain’s volcanoes.” Quoted from the USGS Newsroom.
We have posted views of Earth from NASA’s Suomi satellite that show night illumination and natural gas flaring for oil industry sites in the Bakken Formation, Eagle Ford Shale, Alaska North Slope, United States Gulf, Mexican Gulf, Venezuela Orinoco Field, Brazil offshore basins, North Sea, North Africa onshore, west Africa offshore, and Persian Gulf.
“Brazil is the 8th largest total energy consumer and 10th largest producer in the world. [...] Discoveries of large offshore, pre-salt oil deposits could transform Brazil into one of the largest oil producers in the world.” Quoted from the Energy Information Administration country report.
“Peru’s cloud forests are some of the most biologically diverse ecosystems in the world. Researchers have new evidence that shows rapid 21st century warming may spell doom for tree species in Peruvian cloud forests, with species losing 53 to 96 percent of their populations.” Quoted from the Wake Forest University press release.
“More than 140 million people have permanently settled on high-altitude regions, on continents ranging from African and Asia to South America. The low-oxygen conditions at such high altitudes present a challenge for survival, and these geographically distinct populations have adapted to cope with hypoxia, or low levels of oxygen in the blood.” Quoted from the UC San Diego press release.
An article on the EarthMagazine.org website reports on the use of geophysical tools (ground penetrating radar, electrical resistivity, bulk ground conductivity, gradient magnetometry) for finding graves in Colombia.
“Using an innovative satellite technique, NASA scientists have determined that a previously unmapped type of wildfire in the Amazon rainforest is responsible for destroying several times more forest than has been lost through deforestation in recent years.”
The American Museum of Natural History has an interesting video about the Quelccaya ice cap in the Peruvian Andes, where researchers are collecting cores to document past climate change recorded in the ice.
“Uncertainty about the health of Hugo Chávez, Venezuela’s president, has raised interest in understanding Venezuela’s contribution to U.S. oil supply. Venezuela, a member of the Organization of the Petroleum Exporting Countries, ranks among the 15 largest global oil producers and is the United States’s fourth-largest source of imported oil.” Quoted from the Energy Information Administration article.
Copahue, a volcano on the border between Chile and Argentina began erupting Saturday. An eruption at this time last year cancelled hundreds of flights at the peak of the area’s tourist season.
