Seismograms are an intergral part of detecting earthquakes but the SF State Geosciences department had no graphic clue about yesterday’s 6.0 quake.

Yesterday, the equipment used by the department to measure Californias quakes was unable to even register the shock most of the Bay Area felt.

“Our seismogram is down, but its currently being worked on,” said John Caskey Associate Professor in the Geosciences Department. “The one that we're using on now is mostly going to be for display purposes.”

The Earthquake occurred yesterday morning at 10:15 a.m. according to the U.S Geological Survey (USGS).

Residents in Parkfield, a small populated area of California, experienced the most shaking.

The intensity level was very low and many SFSU students did not feel any rattling. The quake rumbled from Los Angeles to San Francisco, but at different strengths.

“I didn't feel it, I was dancing,” said Marissa Clark a Dance Major. “I figure if it happens, it happens.”

Researchers have being experimenting since the late 1970’s with equipment which assist them by allowing them to predict future earthquakes. It can inform them of the approximate magnitude and where future earthquakes might occur.

The Parkfield quake has been expected since the experiments started, according to the USGS. The experiment is still involves more than 100 researchers at the USGS, universities and government laboratories are involved.

“This one occurred on a small segment on the San Andreas Fault called the Parkfield segment,” said Caskey. “ There is a slight enhanced probability of an earthquake on the southern segment of the San Andreas as a result of the Parkfield earthquake. So they're watching that very closely.”

Even with preparation warnings, many students are not prepared for the next big earthquake.

“I've lived through an earthquake before and it doesn't really frighten me,” said Jesse Garreett, 22, an international relations major. “Personally I have not prepared, I have more on my agenda than to worry about an earthquake.”
