Through the human history of our area people have witnessed the changing earth as it rumbled, spewed, and trembled. And they wondered what it all meant. For centuries local people told stories of how the land was formed and explained the movements of the earth via various lore. Nature was almost unexplainably powerful.
The area around Lassen Peak was visited by several Native groups, who gave it the name ‘Amblu Kai’ or ‘Mountain Ripped Apart’. Clearly the oral history of the area was somewhat accurate, as ancient 11,000-foot-tall Mt. Tehama was destroyed about 27,000 years ago. From this destruction Lassen Peak took dominance.
By the 1800’s, as emigrants arrived in our area, these stories of Earth’s creation seemed fanciful and based on superstition, but few of the newcomers had seen the power of a volcano or witnessed the awesome and terrifying destruction of an earthquake. They were to learn.
As the earth shook, people were frightened. The area around Lassen Peak was particularly active, but Lassen County witnessed its own movement as our county is laced with fault lines.
Although the seismoscope was invented in 132 A.D. by Chinese scholar Zhang Heng, our current method of assigning earthquake severity was created by Charles Richter in 1935. Early accounts of earthquake severity would only describe the force in such terms as ‘severe’, ‘mild’, rolling or ‘a quick jolt’.
No matter how earthquakes were described, people were terrorized by nature’s power. Human propensity to control nature had no effect on the magnificence of the movement of the earth. Early scientists suggested many theories as to how these shifts in Earth’s crust were caused. But still, California rumbled, and people took notice.
The area that is now Lassen County was relatively late in receiving its emigrant population, but when these new arrivals did settle here, they were clearly shown that the earth was in control.
Many millions of years ago a huge upheaval created the range of mountains along the Plumas/Lassen County border which contains Thompson Peak and Diamond Mountain, and these mountains are still changing as we watch.
A very strong earthquake was centered in the area near Thompson Peak on January 24, 1875. The isolated area reported little damage, but a trembling Earth always causes concerns, and this was a sure sign that the mountains were not finished.
On September 22, 1884, at 8 o’clock in the evening a small earthquake shook Susanville and caused no damage to property. But people were still frightened by the swaying earth beneath their feet.
Again, the ground trembled, when on January 24, 1885, a very strong quake was centered in Johnstonville. Then in February 1885 a series of over 60 earthquakes began, some small and some very heavy. Damage was confined to items falling from shelves and other minor issues.
In April 1888 a quake roared through the area preceded by a “rumbling sound”. The quake lasted only seconds and caused nothing but frayed nerves.
Then, in June 1889, earthquake activity in Lassen County took a turn for the worse. At about 10:00 P.M. on Wednesday, the 19th, the heaviest earthquake ever felt in the area sent Susanville residents scrambling into the streets. Buildings swayed side to side sending dishes, glassware and other items crashing to the floor.
People crowded into the streets wearing, in some cases, “the costume, principally, that nature had provided them.” Throughout the night and the next day over thirty lesser earthquakes continued to rattle the nerves of local citizens.
As most of the quakes were announced by a rumbling sound, people would dash again to the middle of the street for safety. Most stayed in the streets all night, afraid to return to their houses.
