Integrated Scenario-based

Assessments of Impacts and

Hazards (ISAIAH)

7th NDRRMC IM-TWG Meeting

Office of Civil Defense, Camp Aguinaldo, Quezon City

27 June 2016

What is Project NOAH?

Specifically, Project NOAH aims to provide:

• flood mitigation system, specifically targeting a 6 hour flood

early warning system for communities along 18 major river

systems;

• enhancement of geohazard maps and;

• enhancement of storm surge vulnerability maps

As per President Aquino’s directive

to put in place a responsive

program for disaster prevention &

mitigation, the Department of

Science & Technology launched

Project NOAH last July 2012 in

Marikina City.

Hazard Maps

How many people / households are in flood, landslide and

storm surge hazard areas?

Which critical facilities (schools, health facilities, evacuation

centers) may be affected by impending hazards?

How many houses made of light materials are inside of

areas covered by Tropical Cyclone Warning Signal?

How many children, senior citizens, PWDs and other at-risk

groups are needed to be evacuated in anticipation of

hydrometeorological hazards?

What are the gaps of local governments units in preparing

and responding for extreme weather events?

Let us consider these questions…

Program Title: Nationwide Operational Assessment of Hazard

Project Title: Integrated Scenario-based Assessments of Impacts and Hazards (ISAIAH)

Implementing Agency: UP National Institute of Geological Sciences

Project Leader: Dr. Alfredo Mahar Francisco A. Lagmay

Cooperating Agencies

1. National Disaster Risk Reduction

Management Center (NDRRMC)

2. Department of the Interior and Local

Government (DILG)

3. Department of Social Welfare and

Development (DSWD)

4. Ateneo Java Wireless Competency Center

5. Philippine Statistics Authority (PSA)

Objectives • To create municipal level risk assessment and incident

reporting and visualization tools

• To map exposure elements such as population, buildings and critical facilities

• To assess vulnerability to hydrometeorological hazards based on available datasets

• To evaluate the Disaster Risk Reduction and Management capacities of local government units

• To train and communicate with end-users in the use of the NOAH website and its allied tools

• To provide data and risk information required by NDRRMC during extreme weather events thru the PDRA system

Vulnerability

The characteristics and circumstances of a

community, system or asset that make it

susceptible to the damaging effects of a

hazard (UNISDR, 2007)

RA 10121 (Philippine DRRM Act of 2010)

pinpoints the source of vulnerability from:

• Physical factors

• Social factors

• Economic factors and

• Environmental factors

WebSAFE

WebSAFE allows users to

calculate the number of

population exposed to a

particular risk such as flood

hazard in question format.

For example: In the event of a

100-year flood in Quezon City,

how many people (population)

will need evacuation?
