As of this posting, the training has already wrapped up earlier today but I just wanted to share the importance of having this training with the LGU technical personnel and which can help later on in the data gathering and analysis. This will then generate a report for reference to various plans of the City Planning and Development Office and other related offices.

Day 5 started with the Introduction to UAV (Unmanned Aerial Vehicle) Survey, with the type of drones used for surveying hazard damage assessment. There are also existing Memorandum Circular that should be followed by each person that would want to fly a drone.

The personnel from the Mines and Geosciences Bureau discussed the Rain-Induced Landslide and Flooding in the PH in a detailed fashion and I got to learn new terms related to the topic such as Creep, Debris flow, Mudflow, and Debris Avalanche. Of course, they are also used in Magic cards but what the heck.

Anyhow, we have also learned the most causes of flooding and on Geohazard Mapping. Next was the Introduction of PHIVOLCS-REDAS Earthquake and Tsunami Alerting Module, with PHIVOLCS Monitoring Setup, and PHIVOLCS Warning Procedures. I think the details here can be found at their website in a complete guide manual.

Next up was the Tsunami Warning Announcement Diagram which also was an inclusion of the main REDAS software. There is a Warning Announcement Document that can be used as a basis in case an actual tsunami event happens.

The next talk, Earthquake Risk Assessment Methodology, is to be used in identifying building earthquake damage levels for risk assessment. The speaker presented the case study of the Bohol Earthquake, in the assessment of the structures types in the area.

They have also explained the Earthquake Impact Assessment Calculation Method- the
Risk Computations Using Survey Data from the REDAS software. Another set of exercises were then performed with the ground shaking tab of the Seismic Hazards and Risk Assessment tool function.

To conclude, it was another jam-packed day of lectures and hands-on though I would need to get a copy of all of the pdf of the presentations so as to compile simpler steps of the process of hazard assessment. Ma’am Donna would be the primary source.

That is a wrap, until the next post.

I am currently attending the REDAS Software training by PHIVOLCS & representing Iloilo City together with Ma’am Donna Magno of the City Disaster and Risk Reduction Management Office. It is already Day 3 as of this posting but I’d just like to add here the notes I have taken on the first day of the training workshop just so for backup purposes and future reference.

Lecture 1
Cartography – definition, uses
Maps – basics, elements, coordinate system, projection, maps in REDAS, types of maps, contour lines
Geographic Information System – definition, applications
Google Earth

Lecture 2 – Earthquake and Earthquake Hazards
Renato U. Solidum, Jr. DOST-Philvolcs

Types of Earthquake (Volcanic, Tectonic)
Plate tectonics
Earthquake activity in the Philippines – active faults, trenches
Magnitude, intensity estimation
Disaster losses
Goals of DRRM – reduce losses, ensure effective & efficient response, recover fast and build better.
Disaster imagination
Key actions for DRR – identify hazards and risks, monitor, warn and disseminate information, respond properly and timely
Earthquake-related Hazards

Faults – fractures where rock movement has taken place and earthquakes have been produced.
– Active faults are those that moved in the last 10,00 years.
Strike slip, Normal, thrust-reverse
Valley Fault System
Phivolcs Fault Finder – hazard and risk information through web application.
URL: faultfinder.phivolcs.dost.gov.ph
Earthquake hazard – Ground Shaking
Strength of Earthquake: Magnitude – energy released during the earthquake event.
Intensity – effect or felt strength at the surface
PHIVOLCS Earthquake Intensity Scale (PEIS) – ranks from I to X
Liquefaction – loose, water-rich sediments behave like liquid during strong ground shaking.
Liquefaction prone areas – water-saturated, low-lying
Landslide
Tsunami – natural signs of an impending local tsunami
Tsunami scenario
PHIVOLCS Geo-Portal – a web GIS-base portal, enables the public to view and collate hazard and risk maps.
Earthquake Preparedness and Risk Reduction activities

Volcano – classifications: active, potentially active, inactive
Volcanoes formed from divergent/convergent plate boundaries.
Subduction Zone (Arc) Volcanism – origin of Philippine Volcanoes
Volcanic hazards – Ashfall, lava flows, pyroclastic flows, lahar
Lahar – Flowing thick with mixture of volcanic sediments and water triggered by rain.

Volcano Risk Reduction – monitoring and hazards mapping, land use plan, avoidance/evacuation.
Volcano monitoring – with various devices/system.
Visual and other sensory observations.
Volcano Alert Level Scheme

Afternoon – REDAS Software installation

Software preliminary setup, requirements and installation.
