Although many people think that California “owns” all the earthquakes, Ohio also has its share of faults. Unlike another earthquake that woke people on another April 18, 102 years ago, this quake was fairly mild.
Two of UC’s earthquake experts have had extensive experiences with earthquakes. Attila Kilinc is a professor in the Department of Geology in the McMicken College of Arts & Sciences and G. A. Rassati is an assistant professor in the Civil and Environmental Engineering Department in UC’s College of Engineering. Rassati just returned from presenting several seminars in Europe on structural engineering.
Rassati was inspired to become a structural engineer specializing in earthquakes after experiencing one as a child in Italy.
“I was four years old when a strong earthquake struck my region in Italy,” says Rassati. “I have a very strong memory of my Dad trying to get me out of my little bed but he couldn’t get to me. Earthquakes have always interested me ever since.” Rassati has studied the structural and seismic effects on infrastructures, especially buildings.
"Unfortunately, the money is drying up for earthquake research. I'm afraid it's going to take another big one to draw attention to that," says Rassati. "And we're overdue."
Q&A with Attila Kilinc
A: Between 1776 and the present, 170 earthquakes have been charted in Ohio of magnitude 2.0 or greater. There have been at least 150 below magnitude 2.0, which averages out to approximately 1½ earthquakes a year. This latest was not a first, severity-wise: Several others measured inbetween 5.3 and 5.4; in 1980, for example, an earthquake in Sharpsburg, Ky., measured 5.2.Q: Can anyone predict a “big one” ever hitting the Midwest?
A: The U.S. Geological Survey says that references to unusual animal behavior before a significant earthquake date to 373 BC in Greece. Kilinc says that for many years, Chinese scientists in particular watched what they called precursors, such as animal behavior and radon in water, in terms of earthquake prediction. None of the signs they were watching for, he adds, showed up in Tangshan, China, on July 28, 1976. That’s the day an estimated 247,000 people died in China’s deadliest earthquake of the 20th century. Its magnitude was 7.8.Q: For those who have been through a major earthquake in California, this has to seem like barely a rumble. Yet, for many Midwesterners, an earthquake can literally rattle the nerves! How seriously should we take such an occurrence and is there any preparation one can make for an earthquake?
A: Residents of any area should always be prepared for earthquakes, tornados, hurricanes and so forth, making logical preparations that are similar no matter the disaster. For example, if there’s a strong earthquake or tornado and electricity is lost, many people’s first reaction is to strike a match so they can see — and can cause an explosion in a gas line. Also, people tend to want to rush out of an area affected by an earthquake. Kilinc, a former California resident who’s been through many temblors in the Bay Area, says that most people are killed “trying to get in or out,” so staying put is important. Little things matter, too, such as not putting dangerous chemicals on upper shelves in a laundry room.Q: Finally: Another widely spread urban legend claims that California will someday fall into the ocean. While that’s not going to happen, how long could it take, as the Pacific Plate moves, before Los Angeles is close to San Francisco?
A: California, Kilinc says, “will never fall into the ocean” because of a boundary called a transform fault. San Francisco will shift south and Los Angeles, north — but it will take a “long, long time” for them to meet. The USGS says that tectonic forces “in this part of the world are driving the Pacific Plate in a north-northwesterly direction with respect to the North American plate at approximately 46 millimeters per year in the San Francisco Bay Area."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
