4.

The word/s that describes VULNERABILITY in the statement:

“In December last year, the Philippines was struck by two back-to-back earthquakes in two days. A magnitude 6.9 earthquake struck off the coast of the southern Philippines on 4th December 2023. Earthquakes occur frequently in the Philippines, which is located in the Pacific Ring of Fire, a seismically active region. ”

seismically active

5.

The type of fault present in the photo

a)

Reverse

b)

Normal

c)

Left lateral

d)

Right lateral

6.

The DISASTER RISK COMPONENT that is described as robust in the statement

“Homes and infrastructure have been significantly damaged, and a huge number of buildings were destroyed. The Philippines, home to a large number of rural areas, is generally ill-equipped to deal with such natural catastrophes, contrarily to some countries – such as Japan – which have developed a “robust building code requiring all buildings to be built to withstand earthquakes.”

a)

Hazard

Coping capacity

d)

Vulnerability

(a)  

9.

Mt. Mayon, with its picture-perfect cone shape, is the result of alternating layers of lava from different eruptions through the years. It has a slope of less than 33 degrees and a height of 2km making it this type of volcano.

a)

a)

True

b)

False

19.

The TYPE OF HAZARD described in the following statement:

“Magarzo said a sinkhole is the most dangerous type of hazard because it has no indication of when it will appear. Once there is no support underneath, it will just collapse along with any structures standing in the affected area, she added. She said the agency has recommended lessening the weight of the structures that stand on the limestone, especially for one-story building.”

Natural

b)

Technological

c)

Socio-natural

22.

The DISASTER RISK COMPONENT described by the statement:

“In 2013, the Phivolcs released different comics based on real stories of Filipino survivors of the 2011 Sendai earthquake. These were written in Filipino.

But while these projects can really be helpful to Filipinos, Solidum has always emphasized the importance of community-based preparedness, especially during locally generated tsunamis.
