There are generally two types of hay bales. With quite different weights. The most common ones that people buy at feed stores or the farmer, and can be moved by one person, are the type you may have bucked into the barn for your uncle who had a farm when you were a teenager. They are around 3-4 feet long by 24x18 inches square.
How Earthquakes Happen. An aerial view of the San Andreas fault in the Carrizo Plain, Central California. An earthquake is the vibration, sometimes violent, of the Earth's surface that follows a release of energy in the Earth's crust. This energy can be generated by a sudden dislocation of segments of the crust, by a volcanic eruption, or event by manmade explosions.
Multiple earthquakes have struck Southern California this month, causing minor damage and reminding residents that large swaths of the western U.S. are susceptible to earthquakes that could cause major damage if or when they finally occur. In Nevada, itâs not a question of if âthe big oneâ will hit, but when. The state is the third-most seismically active state in the nation, behind California and Alaska. There are active earthquake faults in nearly every part of the state.
