Good morning classmates! We will report about earthquakes. A family in Masbate province were left trapped when their house collapsed. There's no left of tsunami but authorities aren't warning people to prepare for aftershocks. On the next news, there is Janice to deliver a message about commonly used methods of reducing earthquake risks. Janice?
Yes, Maru. Thank you! Good morning everyone. Here are some methods for us to know to prevent or reduce the risks of an earthquake. 1. Effective recording and interpretation of ground motion. This assists in providing alerts and warnings especially to high risk or vulnerable areas for preparation and emergency response.
2. Constructing seismic hazard maps. It serves as basis for disaster management information like locations for evacuation and evacuation routes. The anticipated intensity of ground shaking is represented by a number called the peak acceleration or the peak velocity.
3. Developing resistant structures. Resistant structures are able to withstand collapse by redistributing forces caused by seismic waves through shear walls. Developing engineered structural designs that are able to resist the forces generated by seismic waves can be achieved either by following building codes based on hazard maps or by appropriate methods of analysis.
