pen
If indoors, move quickly to a door frame - it is among the stronger structures in a building, and thus more resistant to collapse.
its so your not to close to the earthquake other wise you get more shakes and jiggles
Yes.
The part of the seismograph that moves during an earthquake is called the pen.
how do particles move in the ground when an earthquake occurs
The most violent shaking during an earthquake typically occurs closest to the earthquake's epicenter, where the seismic waves are strongest. As you move further away from the epicenter, the shaking intensity decreases.
At the epicentre which, is the central point from which it originates.
A base isolated building is a structure that is designed to have a flexible foundation system to help it withstand the lateral forces generated during an earthquake. This system decouples the building from the ground motion, allowing it to move independently and reduce the impact of the seismic forces on the structure. Base isolation is a common engineering technique used to protect buildings and structures in earthquake-prone areas.
it moved a whole 8 feet
The seismograph's mass, typically a heavy weight or pendulum, remains stationary during an earthquake. Its inertia allows it to stay in place while the ground moves. This mass is connected to a recording device that captures the motion caused by seismic waves during an earthquake.
Surface waves are the earthquake waves that move in a horizontal direction along the ground. They are responsible for the most damage during an earthquake due to their side-to-side shaking motion.
