• It produces waves of up to a maximum of 1 meter.

• It develops from undersea disturbances.

Which of the following does not influence the severity of a storm surge?

• the shape of coast

• the strength of wind

• the salinity of seawater

• the angle of approach of the typhoon

Which describes the shape of the coast of Manila Bay?

• inward bow

• outward bump

• inward obliquely angular

• straight

Which describes how the shape of the continental shelf affects a storm surge?

• a gentle-sloped shelf allows water to travel towards land more easily than a steep-sloped shelf.

• a steep-sloped shelf allows water to travel towards land more easily than a steep-sloped shelf.

• a gentle-sloped shelf allows strong winds to push water more gently towards the land.

• a steep-sloped shelf blocks the wind that pushes water into the land.

Which of the following correctly relates the angle of approach of the typhoon to the severity of storm surge?

• A typhoon that is moving straight toward the coastline can create a bigger storm surge than one that approaches at an angle.

• A typhoon that is moving straight toward the coastline can create a smaller storm surge than one that approaches at an angle.

• The angle of approach influences the speed of storm surge as it enters the land.

• A typhoon approaching at an angle will create storm surges only when there is high tide.

Which shows how a storm surge warning system is coded?

• Four colors indicate different expected wave height

• Three colors indicate the different lead time before an expected storm surge

• Four colors indicate the distance of water from the sea

Which describes the difference between a tsunami and a storm surge?

• A tsunami results from underwater movement while a storm surge results from typhoon winds.

• A tsunami reaches land as soon as the earthquake occurs while a storm surge can take several hours to reach land.

• A tsunami cannot be predicted while a storm surge is easily predicted.

• A tsunami approaches land at a greater speed than a storm surge.

A storm surge is expected to occur and the wave height is higher than an average single-storey house. What kind of action should be taken based on the PAGASA storm surge warning?

• The storm surge is classified as RED and therefore evacuation is already mandatory.

• The storm surge is classified as expected and decision to evacuate should be discussed by the family.

• A storm surge can possibly occur and the house should be prepared for possible flooding.

• A storm surge will likely occur within the next three days so the family should discuss evacuation plans.

A coast is lined with wall structures designed to reduce the impacts of storm surges. Which best explains how those structures help against storm surges?

• The wall reduces the powerful wave action before the water hits the land.

• The wall prevents the water from entering the land.

• The wall diverts the direction of the wave back to the sea.

• The wall allows PAGASA to measure the height of the storm surge before it enters the land.

Which of the following will be the best course of action if a there is an Orange warning for storm surge and your house is by the beach in the area of concern?

• Cover all house items that may be wet when it floods.

• Stop your regular activity and stay inside your house

• Unplug all electrical appliances after charging all communications devices.
