Reawakening of Icelandic Volcano!!!

The volcano consists of inter–connected conduits, sills, and dikes that allow magma to rise from deep within the Earth.

Months of volcanic restlessness preceded the eruptions this spring of Icelandic volcano Eyjafjallajökull, providing insight into what roused it from centuries of slumber.

Mega-Cities in Earthquake Zones Await Disaster

25quakespan-cnd-articleLarge

Construction at the Atakoy Lisesi school.  Istanbul has a program to secure its schools against earthquakes.

As Mustafa Erdik, the director of an earthquake engineering institute in Istanbul, surveys the streets of this sprawling mega-city, he says he sometimes feels like a doctor scanning a crowded hospital ward.

It is not so much the city’s modern core, where two sleek Trump Towers and a huge airport terminal were built to withstand a major earthquake that is considered all but inevitable in the next few decades. Nor does Dr. Erdik agonize over Istanbul’s ancient monuments, whose yards-thick walls have largely withstood more than a dozen potent seismic blows over the past two millenniums.

Upside-Down Answer for Deep Mystery: What Caused Earth to Hold Its Last Breath?

100217131140-large

Volcano eruption

When Earth was young, it exhaled the atmosphere. During a period of intense volcanic activity, lava carried light elements from the planet’s molten interior and released them into the sky. However, some light elements got trapped inside the planet. In the journal Nature, a Rice University-based team of scientists is offering a new answer to a longstanding mystery: What caused Earth to hold its last breath?

African Desert Rift Confirmed As New Ocean In The Making

New research confirms that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea.

In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial.

Ancient And Bizarre Fish Discovered: New Species Of Ghostshark From California And Baja California

090922095816-large

This is an Eastern Pacific black ghostshark (Hydrolagus melanophasma), a new species from California and Baja California.

New species are not just discovered in exotic locales—even places as urban as California still yield discoveries of new plants and animals. Academy scientists recently named a new species of chimaera, an ancient and bizarre group of fishes distantly related to sharks, from the coast of Southern California and Baja California, Mexico.

Lamprey mouth

In addition to providing fundamental insights into the early evolution of the estrogen receptor, research by a team at the University of California, San Diego School of Medicine may lead to a contraceptive for female lampreys – a jawless fish considered an invasive pest species in the Great Lakes region of the United States. This could prove important to the Great Lakes region, where lampreys aggressively consume trout, salmon, sturgeon and other game fish.

Super-computer Provides First Glimpse Of Earth’s Early Magma Interior

Earth…

By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, two UC Davis geochemists have produced the first picture of how different isotopes of iron were initially distributed in the solid Earth.
