Why Palawan Has Lower Typhoon Risk
Palawan runs northeast to southwest along the western edge of the Philippine archipelago, facing the West Philippine Sea rather than the open Pacific. This position sits largely outside the primary typhoon corridor that carries most storms entering the Northwest Pacific Basin across Luzon, the Bicol Region, and the Visayas, giving Palawan meaningfully lower typhoon exposure than provinces on the Pacific facing side of the country.
According to the Joint Typhoon Warning Center, the Northwest Pacific Basin sees an average of 26.6 typhoons and tropical cyclones each year, with activity peaking between July and November. Palawan can still be affected during this window, particularly by storms that cross through the central Philippines, but the province's western position reduces both the frequency and intensity of direct hits compared to eastern seaboard provinces.
Palawan's earthquake exposure is also comparatively modest. Historical seismic activity in the province includes moderate events such as a magnitude 5.8 earthquake in 1940, a magnitude 5.3 event in 1981, and a magnitude 5.4 event in 2001, none reaching the higher magnitude ranges recorded elsewhere along the Philippine section of the Pacific Ring of Fire.

Economic Risk from Typhoons in Palawan
Modeled loss data from the World Bank's Philippines Catastrophe Risk Assessment (2018), developed with AIR Worldwide using historical and simulated storm catalogs.
On a long-term average basis, Palawan is expected to incur 56 million PHP per year in losses to public and private assets from typhoons and earthquakes combined. Over the next 50 years, Palawan has a 40% chance of experiencing losses exceeding 0.9 billion PHP, and a 20% chance of exceeding 1.3 billion PHP.
Typhoons still account for the large majority of Palawan's disaster-related economic loss, roughly 18 times greater on average than losses from earthquakes, though both figures are small relative to most other Philippine provinces.

Modeled Typhoon Loss by Return Period
A return period estimates how often a loss of a given size is likely to occur. A 100-year return period means that scale of loss has roughly a 1% chance of happening in any given year.
| Exceedance Probability | Return Period | Direct Loss (PHP Millions) | % of Asset Value | Emergency Loss (PHP Millions) |
|---|---|---|---|---|
| AAL | N/A | 54 | 0.0% | 7 |
| 10.0% | 10 years | 110 | 0.1% | 15 |
| 3.3% | 30 years | 473 | 0.3% | 60 |
| 2.0% | 50 years | 662 | 0.4% | 84 |
| 1.0% | 100 years | 898 | 0.5% | 116 |

Palawan vs. Nearby Provinces
Average annual loss from typhoons and earthquakes, compared across Palawan and nearby provinces in the western and central Philippines.
Palawan carries the lowest combined typhoon and earthquake average annual loss among nearby provinces, consistent with its West Philippine Sea facing position outside the main typhoon corridor.

How much does Palawan lose to typhoons each year?
On a long-term average basis, Palawan incurs about 54 million PHP per year in direct losses to public and private assets from typhoons alone, according to World Bank and AIR Worldwide modeling. Typhoons account for roughly 95% of Palawan's combined typhoon and earthquake losses.
Why is Palawan's typhoon risk lower than other provinces?
Palawan runs northeast to southwest along the western edge of the Philippine archipelago, facing the West Philippine Sea rather than the open Pacific. This keeps it largely outside the primary typhoon corridor that brings most storms across Luzon, the Bicol Region, and the Visayas.
What is Palawan's worst-case typhoon loss scenario?
At a 100-year return period, roughly a 1% chance in any given year, Palawan could see direct typhoon losses of up to 898 million PHP, equal to about 0.5% of the province's total asset replacement value.
Are typhoons or earthquakes a bigger risk in Palawan?
Typhoons are the larger risk of the two, though both are comparatively low in Palawan. The province's average annual loss from typhoons is about 18 times greater than its average annual loss from earthquakes, 54 million PHP versus 3 million PHP.
How does Palawan compare to nearby provinces for typhoon risk?
Palawan carries the lowest modeled typhoon and earthquake average annual loss among nearby provinces such as Occidental Mindoro, Oriental Mindoro, Antique, and Negros Occidental, reflecting its sheltered position facing the West Philippine Sea.
What percentage of Palawan's assets are at risk from typhoons?
Palawan's total asset replacement value is about 166 billion PHP, of which 74% (124 billion PHP) is private property and 26% (42 billion PHP) is public infrastructure. At a 100-year return period, modeled typhoon losses could reach about 0.5% of that total value.
