The Loma Prieta Earthquake: The Ground Begins to Rumble

On October 17, 1989, at 5:04 p.m. PDT, the Loma Prieta earthquake struck. This earthquake, registering a magnitude of 6.9 on the Richter scale, had its epicenter in the Santa Cruz Mountains, about 60 miles (97 km) south of San Francisco. But don't let the distance fool you; the effects were felt far and wide. The shaking lasted for about 15 seconds, which, believe it or not, felt like an eternity for those experiencing it. The Loma Prieta earthquake was named after Loma Prieta Peak, the highest point in the Santa Cruz Mountains, near where the rupture occurred on the San Andreas Fault. This area is known for its seismic activity, making it a prime location for earthquakes. The tremor was caused by the sudden release of built-up stress along the fault line. The San Andreas Fault is a major fault line that runs through California, and it's responsible for a significant amount of the state's earthquakes. This particular quake was a result of the movement and shifting of the tectonic plates beneath the earth's surface. The movement wasn't just a simple slide; there was a complex process of energy release that caused the intense shaking felt throughout the region. The initial shock caused many people to panic; many buildings and structures were simply not prepared for this type of earthquake. Those 15 seconds were enough to create widespread panic and initiate significant damage. Buildings swayed, streets cracked, and things began to fall from shelves and walls. These moments were etched in the memories of those who lived through it.

The World Series Interruption
