How do you earthquake proof a city?
To be earthquake proof, buildings, structures and their foundations need to be built to be resistant to sideways loads. The lighter the building is, the less the loads. This is particularly so when the weight is higher up. Where possible the roof should be of light-weight material.

What is Digdig fault?
The Digdig Fault is the northern active splay of the PFZ as suggested by the documented youthful geomorphic features and confirmed by the appearance of a surface rupture along most part of the fault during the July 16, 1990 earthquake.
What is earthquake zone2?
Zone 2. This region is liable to MSK VI or lower and is classified as the Low Damage Risk Zone. The IS code assigns a zone factor of 0.10 for Zone 2. It is the zone with low chances of having earthquakes.
How do you protect a town from an earthquake?
Go to an open area away from trees, telephone poles, and buildings. Once in the open, get down low and stay there until the shaking stops. The area near the outside walls of a building is the most dangerous place to be. Windows, facades, and architectural details are often the first parts of the building to collapse.

Is the Philippines under a Transpressive or Transtensional tectonic setting?
The difference in tectonic regimes as observed from the two separate networks may mean that, at the regional scale, the central Philippine Mobile Belt is undergoing a transpressive deformation (strike slip plus compression), while at the local scale, Leyte Island is under transtensional tectonics (strike–slip plus …
Is New Zealand seismically active?
New Zealand is located on the edge of a zone of intense seismic activity known as the Ring of Fire. The interaction as these plates collide is responsible for much of New Zealand’s geography.
Why are there so many earthquakes in the Philippines?
List of earthquakes in the Philippines. The Philippines lies along the Pacific Ring of Fire, which causes the country to have frequent seismic and volcanic activity. Many earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region. The largest was the 1918 Celebes Sea earthquake with M w 8.3.
What are the building codes in the Philippines?
If the type and quality of building construction plays a critical role in mitigating the human impact of earthquakes, can we find salvation in our own building codes and standards? A building’s resilience to seismic stress is determined by its compliance with the National Structural Code of the Philippines (NSCP).
