MHE : The Phillipines Flashcards
WHat are the 3 top countries @ most risk based on the Risk Vulnerability index?
Vanautu, The Phillipines, and Tonga
where is the Phillipines?
It an archipelagic countru that lies on Western Pacific Ocean + consists of 7,600 islands. It has a pop of 106.7 million. The capital city is Manila. It is situated on the Pacific ring of FIre and and it lies near equator in tropic region thus is liable to many diff hazards essp EQ’s and typhoons.
what is the population density in the Phillipines?
334ppl/km2
Why is the Phillipines so vulnerable to hazards?
Mainly due to its geographical location
- Position on the Western rim on the PROF brings EQ’s and volcanic activity w/ secondary hazards such as lahars
- Position near the equator w/ lat= 12.87, it is in perfect band to be affected by the tropical storms bc they occur @ 5-20 degreees N and S of the equator.
- Tropical storms also bring secondary hazards such as landslides, and flooding.
- The sea temp is also 27 degrees, which is perfect conditions for a tropical storm to develope.
- its made up of 7,600 smol islands –> bc land mass is so small, tropical storms don’t lose energy when they cross through phillipines, they b/w land and sea quickly and thus storm quickly regains energy. –> high magnitude, devastating typhoons. –> storm surge.
- There have been > 10k eq’s since 70’s –> if eqs occur underwater –> risk of tsunamis, can lead to flooding.
El nino period also brings periods of drought in the Phillipines.
- The large population that is v v dense esspi in Megacity manila –> more ppl in poverty w/ lack of education on how to prep etc for hazards –> have more to lose,
Bc the maj population is youthful, whgen disaster strikes economy is badly affected
Which one is worse?
Typhoons have been leading hazard causing damage in the Philipines –> on avg 19 hit area anually. The deadliest typhoon strike was Haiphong 1981 –> 20k deaths.
Typhoon —> flooding –> 2nd most devastating hazard –> results in loss of livlihood, life, livestok, buildings, possessions etc. (mostly occur due to the monsune climate) and powerful thunderstorms formed in the pacific.
Ocucrance of drough as a resukt of El Nino often impact the area + has affected 6mill before.
Severe rainfall expereineced can lead to landslides as soils become saturated w/ water –> soils fall down + collapse underneath themselves.
Bc phillipinnes is on a plate boundary –> more likely to experience seismic hazards (ie volcs and eq’s).
what is the secondary hazard associated with Earthquakes?
Tsunamis, rockfall, after shocks liquefaction ,tsunamis
what is the secondary hazard associated with volcaboes
Pyroclastic flows, lahars, ash fallout, tephra, release of gases lava flow
what is the secondary hazard associated with Typhoons?
flooding, landslides, storm surges and tornados.
what are the hazards were focusing in the philipenes?
Earthquakes : Bohol 2013, Volcanoes : Mt Pinatubo 1991, Tropical storm : Typhoon Haiyan.
what is the nature of the earthquakes that occur in the Phillipines?
EQ’s occur regualrly in P.Piines. B/w 2000-2013, 17 eq’s occured w/ most being mag 5.6 or above –> death, destruction of the infrastructure + businesses. The eq’s occur often bc it lies on the pacific ring of fire and thus suseptible to volc and eq’s
when did the Bohol Earthquake occur?
October 15th 2013.
what was the magnitude of the Bohol earthquake?
7.2
How many ppl were killed + injured and how many buildings were damaged as a result of the eq in Bohol?
> 200 dead.
800 injury
73k building sdamaged –> most noticable was the Church of Our lady of light, the oldest and largest running church in the province.
What was the depth of the focus, how much energy was released.
depth of focus : 12km, energy released was equated to the energy released when 32 bombs dropped on HIroshima
Overall how many ppl were affected?
1.3 million ppl
How many ppl were displaced?
340,000
what was the warning that the USGS gave?
a yellow warning that some “casualties and damage is possible + impact should be localised” –> not true evidently, past warnings have required more local and reginal responses.
What are some effects of the Bohol earthquake?
- Damage cost : 2.2bn Filipino pesos
- Nearly 7100 residential homes were lost –> homelessness increased @ a large scale
- Direct hosipital in Loon collapsed so diff to treat injured members of public –> the collapse also killed patients and doctors (unknown no.)
- 32 bridges, National road and 13 other road sections were damaged –> limited aid effort.
- Several flights from Cebu to Bohol were put on hold to check safety status of the airport.
- Many bohol residents were left w.o adequate clean safe drinking water and sanitary services after the quake –> increase in public health issues(ie spread of comm diseases, diarrhoea, and other H20 Borne diseases).
- Many health centers were deemed as useless due to the damage they endured –> resulted in makeshift wards outside buildings, not safe or sanitary.
- The earthquake left 25 totally and 111 partially damagfed health centers + facilites –> slowed providsion of medicines, and resulted in the destruction of the cold chain system to transport vaccines.
- Many pppl had PTSD and were too afraid to go back inside builkdings, for fear they may collapse again. (pscological trauma) many slept in temporary shelters
- 1 in 5 homes in Bohol recieved an electrical power disruption a week following the event.
what are some responses to Bohol earthquake?
- State of Calamity expressed on oct 15th
- National Commission for Culture and the Arts expressed commitment to rehabilitate the 10 heritage churches damaged by the quake.
- Oct 15 –> National Police deployed 271 personell , 27 vehicles abd declared a full alert system in Bohol. They monitored effects of eq since
- Presidnet Benigno visited Bohol and Cebu to inspect the damage done to its offices –> 51 mins after his visit a 5.1 magnitude afthershock occured.
- WHO proveded manpower, equipmnent, training and supplies, meds and weather tents to serve patient consultation areas, a birthing center which was needed bc 8k births had been expected in the several weekes following.
- WHO also repaired some damaged infrstrcuture nd set up 25 barangay health stations and 14 tents w. sealed in walls and flooring as rural health units.
- The govt of Davao CIty pledged $3 mill cash assistance.
- UN WFP stationed 1000 Tones of rice and 15T of high energy biscuits in Cebu + Bohol for ppl who lost everything
- Red Cross sent volunteers and donated money towards releif efforts to depressed areas.
- Oct 25 : UN called international community to raise $46.8million in aid
- Bohol residents were paid in a food for work scheme where thier mushroom farming was utilised, this scheme was implemented by the Beureu of Fisheries + agri , and the Philipine COconut Authority. `
What is the nature of a volcanic eruption?
In the philipenes ,eq’s are frequent, bc Philipenes lies onthe pacific ring of fire. They are essp destructive bc surroundign the volcanoes usally lies a city or barangay. Many occur inthe philipines bc its in line with the convergent boundary of the Philipine and pacific plate and thus subduction zones have resulted in alot of volcs.
- they are v v destructive to the phillipine ppl bc many live in poverty and thus when damage is done it can be v v hard to climb out of povery, thus will rebuild w. pooere qual homes , liable to same destrcutuion again cycle repeats. + they are vulnerable again.
Many ppl have become traumatised ands some have major skin injuries causing this, others may never work again –> damaging to the economy
Lahars which occur after sometimes due to heavy rains poses as secondary hazards.
when did the Mt Pinatubo earthquake happen ?
June 15 1991
Where is Mt pinatubo located?
On the island of Luzon, at a plate boundary bw Eurasian plate and the Philipine plate. It is one of the chain volcanoes in luzon, on the Lozon Volcanic arc –> occurs as a result of the oceanic philipineplate subductign under the earasian continental plate
