More About Earthquakes...![]() This is an example of some of the different types of foundations that are being used today to build safer buildings. These new technologies that are being developed can be used to analyze the stress of the building when it experiences an earthquake. In 1906, San Francisco did not have these types of innovations and as a result, many of their buildings collapsed. ![]() Above is a picture of an emergency supplies backpack. It's just one of the many types of emergency supply bags you can purchase. However, you don't have to buy one of these bags. You can always create your own to suite the needs of your family. ![]() This is a diagram that shows exactly how the movement of tectonic plates, the casuse of earthquakes, also serves as the underlying cause for tsunamis. |

Where do Earthquakes Mostly Happen in the U.S.A ?
-Predominate in the border of the Pacific and North American Plate and Alaska
-Along the San Andreas Fault (California)
-Along the Denali (Alaska)
How are cities changing building standards to address the possibility of earthquakes?
-Building Codes are needed to be followed
-Enginneers understand the stresses that earthquakes put out and from that, create buildings to be able to withstand any earthquake
-Instruments are place under buildings to see how they respond
-new technology is being used in buildings, such as base isolators to help prevent the damage of earthquakes to a building
Can earthquakes be predicted and/or prevented? What are researchers doing in the field of earthquakes?
-Tectonic movement is observed
-Seismographs are useful in order to determine an earthquake's magnitude
-Instruments measure the velocity of seismic waves
What is a tsunami? How is it related to earthquakes? What are the dangers of tsunamis?
-Tsunami: a succession of waves that are created by a disturbance on the sea floor that is perpendicular to the natural movement of the wave
- Earthquakes can cause tsunamis
- When an earthquake occurs, it can shift large areas of the sea floor, creating a tsunami
-Tsunamis travel from 650-800 kilometers per hour! They can be from 10 to 30 meters tall
- When the waters are moving inland, they can uproot almost anything in its path
When the waters are receding, they can drag people, vegetation, buildings, boats, etc. into the water.
How do people prepare for a possible earthquake?
-secure hanging objects or things that could potentially fall if there was an earthquake
-create an emergency and communications plan with you family
-teach children how to dial 911 in case of an emergency
- be prepared and know what to do in case you are separated from your family
-keep emergency supplies at hand (flashlights, batteries, radio, cahs, sturdy shoes, food, water, etc.)
- know where the safest places in your home are |
