Scientists are warning Reno residents to prepare for a major quake following a series of smaller rumbles that have shaken the area for two months, AP reports. The strongest was Friday night’s magnitude 4.7 tremor, which cracked walls and rattled products off store shelves. Now, “a magnitude 6 quake wouldn't be a scientific surprise,” said a seismologist.
Another scientist warned: "We can't put a number on it, but the probability of a major earthquake has increased with this sequence. People need to prepare for ground shaking."
