Huge Quake Possible in Oregon Valley


Scientists have warned for years that a magnitude 8 or 9 earthquake could strike about 30 miles off the Oregon coast, causing huge tsunamis (large ocean waves) and tremendous damage.
Now scientists say these earthquakes could be centered much farther inland and cause severe damage to a larger area, including cities in Oregon such as Portland, Salem, and Eugene.
Geologic evidence suggests that strong quakes in this area occur about every 400 years, plus or minus 200 years. The last one, believed to be a magnitude 9, occurred 300 years ago.

Volcanic Blast Shaped Earth

Study finds eruption split an ancient continent, creating Atlantic Ocean



The largest volcanic eruption in Earth’s history — so powerful it split an ancient supercontinent and created the Atlantic Ocean — spewed millions of square miles of searing lava that extinguished much of life on ancient Earth.
From hundreds of basalt outcrops that rim the Atlantic coasts, scientists have pieced together evidence of the titanic eruption 200 million years ago. Researchers said that the eruption set the fractured landmasses adrift and, by wedging them apart, gradually opened the gulf that created the Atlantic — giving the map of the world the form it has today.
“This is one of the biggest things that has ever happened in Earth’s history. This is a gigantic, igneous event and it all seems to have occurred in an amazingly brief amount of time.”
To reconstruct the ancient catastrophe, a team of scientists analyzed basalt dikes, sills, and lavas from the New Jersey Palisades, the Brazilian Amazon, Spain, and West Africa.
By studying the chemical composition and dating the residual radioisotopes in the basaltic rocks, the researchers determined that the rocks all originated from the same eruption. Once they realized the outcrops were linked, they were able to determine that, in the distant past, the rocks all had been located together at the center of an immense continent called Pangea that once stretched, unbroken, from pole to pole.
70. Name the geologic time period when this major volcanic eruption initially opened the Atlantic Ocean. [1]
_______ Period
MODEL ANSWER GIVEN BELOW
[1] Allow 1 credit for Jurassic Period.
