Why Marinduque Is Typhoon-Exposed
Marinduque sits in the middle of the Philippine archipelago, between Batangas and Quezon to the north and Romblon and Oriental Mindoro to the south. Its position inside the Sibuyan Sea gives it more shelter than Pacific-facing provinces like Albay or Quezon, but the island still lies within the broader typhoon corridor that crosses the country from the Northwest Pacific Basin, and storms tracking through southern Luzon regularly bring damaging wind and rain to the province.
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, the same window Marinduque sees its highest storm frequency.

Economic Risk from Typhoons in Marinduque
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, Marinduque is expected to incur 184 million PHP per year in losses to public and private assets from typhoons and earthquakes combined. Over the next 50 years, Marinduque has a 40% chance of experiencing losses exceeding 3.2 billion PHP, and a 20% chance of exceeding 6.0 billion PHP.
Typhoons account for the large majority of Marinduque's disaster-related economic loss, roughly 5 times greater on average than losses from earthquakes.

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 | 155 | 0.3% | 26 |
| 10.0% | 10 years | 244 | 0.4% | 39 |
| 3.3% | 30 years | 1,055 | 1.7% | 172 |
| 2.0% | 50 years | 1,606 | 2.6% | 282 |
| 1.0% | 100 years | 2,718 | 4.5% | 489 |

Marinduque vs. Neighboring Provinces
Average annual loss from typhoons and earthquakes, compared across Marinduque and its neighboring provinces.
Marinduque carries a notably lower average annual loss than its larger mainland neighbors Batangas and Quezon, consistent with its smaller land area, smaller asset base, and partial shelter within the Sibuyan Sea. Source: World Bank / AIR Worldwide, 2018.

How much does Marinduque lose to typhoons each year?
On a long-term average basis, Marinduque incurs about 155 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 84% of Marinduque's combined typhoon and earthquake losses.
Why is Marinduque exposed to typhoons?
Marinduque sits at the center of the Philippine archipelago, within the Sibuyan Sea, giving it partial shelter compared to Pacific-facing provinces. Storms crossing southern Luzon and the Bicol Region still regularly bring damaging wind and rain to the island, keeping its exposure real even without direct Pacific frontage.
What is Marinduque's worst-case typhoon loss scenario?
At a 100-year return period, roughly a 1% chance in any given year, Marinduque could see direct typhoon losses of up to 2,718 million PHP, equal to about 4.5% of the province's total asset replacement value.
Are typhoons or earthquakes a bigger risk in Marinduque?
Typhoons are the larger risk. Marinduque's average annual loss from typhoons is about 5 times greater than its average annual loss from earthquakes, 155 million PHP versus 29 million PHP.
How does Marinduque compare to other nearby provinces for typhoon risk?
Marinduque carries a much lower typhoon-related average annual loss than its larger neighbors Batangas and Quezon, both of which have far bigger asset bases exposed to typhoon activity. Oriental Mindoro and Romblon see comparatively lower modeled losses than Batangas and Quezon, and are closer in scale to Marinduque.
What percentage of Marinduque's assets are at risk from typhoons?
Marinduque's total asset replacement value is about 61 billion PHP, of which 82% (50 billion PHP) is private property and 18% (11 billion PHP) is public infrastructure. At a 100-year return period, modeled typhoon losses could reach about 4.5% of that total value.
