Joining faults: Unearthing the Hayward-Calaveras Connection Note: AI was used to create the images, locate some sources and clean up some of my grammar One of the most remarkable things about seismology is how "new" it actually is. While the theory of Plate Tectonics was proposed at the turn of the 20th century, it didn’t gain mainstream scientific acceptance until the 1960s—making the foundation of the field younger than I am. Despite our rapid progress, the Earth still holds its secrets tightly. To understand why, you have to consider the sheer scale of what’s under the soles of our feet. The North American Plate is one of the thickest on Earth, reaching depths of roughly 200 km (125 miles) . In contrast, the deepest hole humans have ever bored—the Kola Superdeep Borehole —reached only 12 km . We are essentially trying to diagnose the makeup of an entire planet by barely scratching its skin. This massive gap between our reach and the plate’s depth is exactly why we are st...
