About 95 percent of Japan’s population is at risk of being devastated by a major volcanic eruption, which could happen “at any moment” within the next century, a study revealed. Volcanic activity has reportedly increased recently.
The research, conducted by Japanese scientists, was released on Kobe University’s website on Wednesday.
“It is not an overstatement to say that a colossal volcanic eruption would leave Japan extinct as a country,” the authors said, according to AFP.
In early August, Toledo, Ohio's water turned pea-soup green and undrinkable, but it appears that phosphorus, the most obvious culprit behind the huge bloom of toxic algae, wasn't acting alone. In fact, we don't know too much about what, exactly, is causing Lake Erie's water to turn toxic.
Toxin-producing cyanobacteria occurs naturally in Lake Erie, but it typically doesn't explode into huge blooms that are visible from space without a few key ingredients, the foremost among them is phosphorus. In the mid-1960s many lakes and rivers were turning green as cyanobacteria flourished on phosphates that entered the waterways in laundry detergents.
When the blue-green algae blooms and dies, it soaks up oxygen and chokes the life out of water. It not only looks gross and smells worse, but the EPA warns, “cyanotoxins in recreational water and drinking water may cause a wide range of symptoms in humans including fever, headaches, muscle and joint pain, blisters, stomach cramps, diarrhea, vomiting, mouth ulcers, and allergic reactions.”
Hawaii's evacuation maps are based in part on the 1946 tsunami, the most destructive tsunami in Hawaii's recent history. But new research shows that mammoth tsunamis, many times the size of the 1946 event, have struck the island in the past, and may again in the future. Credit: USGS
A mass of marine debris discovered in a giant sinkhole in the Hawaiian islands provides evidence that at least one mammoth tsunami, larger than any in Hawaii's recorded history, has struck the islands, and that a similar disaster could happen again, new research finds. Scientists are reporting that a wall of water up to nine meters (30 feet) high surged onto Hawaiian shores about 500 years ago. A 9.0-magnitude earthquake off the coast of the Aleutian Islands triggered the mighty wave, which left behind up to nine shipping containers worth of ocean sediment in a sinkhole on the island of Kauai
The 1934 drought was by far the most intense and far-reaching drought of the last 1,000 years in North America, and was caused in part by an atmospheric phenomenon that may have also led to the current drought in California, according to a new study.
New research finds that the extent of the 1934 drought was approximately seven times larger than droughts of comparable intensity that struck North America between 1000 A.D. and 2005, and nearly 30 percent worse than the next most severe drought that struck the continent in 1580.
"We noticed that 1934 really stuck out as not only the worst drought but far outside the normal range of what we see in the record," said Benjamin Cook, an environmental scientist at NASA's Goddard Institute for Space Studies in New York City and lead author of a new paper that has been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.
The new study also finds that the same atmospheric pattern of a high pressure ridge over the West Coast deflecting away storms laden with rain last winter was also present over the area during the winter of 1933-34.
