Jones also pointed out the San Gabriel mountains, which exist because they're pinched by the San Andreas and San Jacinto faults. She also pointed out key pieces of infrastructure, including Interstate 15, railroad lines and transmission power lines that would be impacted in a big quake. Jones showed guests a sag pond, which is a body of fresh water that collects along two sides of the fault zone. The first stop on the tour was in an area known as Lost Lake in the Cajon Pass. "Every point on that surface is giving off energy." "When we modeled this earthquake, it started near the Salton Sea and the rupture continued all the way beyond Lancaster. "In a magnitude 7.8, it's 200 miles long," said Jones.
Along the way, Jones described what an earthquake might be like along the San Andreas fault. It started at San Bernardino city hall and went through the Cajon Pass all the way to Big Pines. In 1857, an earthquake of magnitude 7.9 occurred on the San Andreas fault, starting at Parkfield and rupturing in a southeasterly direction for. The most recent earthquake in that area today, was in 1990 in San Francisco which measured around 8.3 on the richter scale but it wasn’t a bad as the one in 1906.The tour lasted nearly four hours. The two slide together caused the earthquake. The San Andreas fault is formed by the Pacific plate sliding north and the North American plate running South.
Knowing now that buildings could not withstand a earthquake with unreiforced brick, the new San Francisco would have buildings that can handle major earthquakes by constructing them so that they sway back and fourth rather than just simply crumbling to the ground killing people. Scientists found out that the earthquake originated north of Oregon and south to Los Angeles a total of 1170 Km. And the capital of California Sacramento that was 120km east of the rupture showed no damage. The earthquake’s most damage were in Los Bonas 30km east of the fault yet there was little damage along towns to the east side of San Francisco Bay such as Berkely, 25km east of the fault. With an intensity of 8 degrees in the Richter scale, the San Andreas earthquake had its epicenter near San Francisco and an 8 degrees intensity in the Richter scale that caused 3000 casualties and a completely ruined city. A road across the fault ended up 21 feet north of the road to the east same with the rivers and creeks. Rivers, roads and power lines were severed and not aligned with its surroundings. After the earthquake, they noticed that the San Andreas Fault shifted a 250-mile long section witch tore roads and fences.

The buildings were made out of unreined forced brick or wood which couldn’t withstand a earthquake of that magnitude. Some sailers on the coast tried to leave but the waves flew the boats around like toys. The old buildings were never made to withstand earthquakes and easily crumbled and fell crushed people. The city was in the middle of a great economic boom and almost all was lost on that day. Gas mains blew and caused massive fires all around the city. The fire could not be stopped because there were now water until the next couple of days. There fire department was efficient but the water pipes that go down the San Andreas Fault were severed. The people who ran in the streets were killed by toppled buildings falling from above. People ran from there houses and some stayed inside the buildings and were crushed. Earthquake San Francisco – 1906 On the morning 12 past 5:00 San Francisco suffered a major earthquake that killed 3000 people, the earthquake lasted for about 40 seconds and was recorded at 8.3 on the Richter Scale. The San Andreas Fault was the site of a massive effort to drill into Earths crust and investigate a fault at depth.
