On Shaky Ground

On Shaky Ground (5:55 min). This is a presentation of various types of earthquake geotechnical hazards and their effects on structures. These hazards include ground ruptures, soil liquefaction and land slides. Since a geotechnical hazard can cause a serious effect on a community, reducing the impact of these hazards must be addressed. This video is part of the "Understanding Earthquakes and Disasters: Photo-Video Presentations for Public Awareness and Education."

Bridges are falling down!

Bridge superstructures and substructures have been damaged in recent earthquakes like the 1994 Northridge earthquake and 1995 Hyogeken-Nanbu earthquake in Japan. Bridges are Falling Down ( 5:52 min) is a photo-video presentation that shows the different types of damages in bridges and some retrofitting techniques. This video is part of the "Understanding Earthquakes and Disasters: Photo-Video Presentations for Public Awareness and Education."

Buildings: Shake, Rattle and Roll

In past earthquakes, many buildings have collapsed or were damaged due to ground shaking or foundation failures. The presentation shows the common types of failures of buildings like soft stories, short columns, torsion, poor detailing and ductility in reinforced concrete columns and beams, and irregular structures. The importance of seismic retrofitting and strengthening of existing structures is also highlighted.

Preparing for the BIG ONE

The key to reducing the impact of earthquake hazards is disaster preparedness and mitigation. Since the Philippines is an earthquake country, it is important to prepare against seismic hazards. This video poses some questions and tips to consider with regards to design and construction of structures, seismic assessment and retrofitting and community disaster preparedness. PHIVOLCS tips before, during and after an earthquake are also presented.
