Why Aurora Is Typhoon-Exposed
Aurora sits on the eastern, Pacific-facing side of Central Luzon, directly along the primary typhoon corridor that crosses the Philippines from the Northwest Pacific Basin. Its long, exposed coastline runs largely unshielded by mountain ranges, putting it in the path of storms making landfall along the eastern seaboard of Luzon.
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 Aurora sees its highest storm frequency.

Economic Risk from Typhoons in Aurora
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, Aurora is expected to incur 283 million PHP per year in losses to public and private assets from typhoons and earthquakes combined. Over the next 50 years, Aurora has a 40% chance of experiencing losses exceeding 3.7 billion PHP, and a 20% chance of exceeding 5.0 billion PHP.
Typhoons account for the large majority of Aurora's disaster-related economic loss, roughly 3 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 | β | 219 | 0.4% | 35 |
| 10.0% | 10 years | 594 | 1.0% | 92 |
| 3.3% | 30 years | 1,505 | 2.6% | 235 |
| 2.0% | 50 years | 2,043 | 3.5% | 344 |
| 1.0% | 100 years | 2,869 | 4.9% | 506 |

Aurora vs. Neighboring Provinces
Average annual loss from typhoons and earthquakes, compared across Aurora and its neighboring provinces. Figures for neighboring provinces are approximate, drawn from the source chart rather than exact labeled values.
Aurora carries a substantially lower typhoon-related average annual loss than larger neighboring provinces like Isabela, Nueva Ecija, and Quezon, consistent with its smaller total asset base. Source: World Bank / AIR Worldwide, 2018.

How much does Aurora lose to typhoons each year?
On a long-term average basis, Aurora incurs about 219 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 77% of Aurora's combined typhoon and earthquake losses.
Why is Aurora exposed to typhoons?
Aurora sits on the eastern, Pacific-facing side of Central Luzon, directly along the typhoon corridor entering the Philippines from the Northwest Pacific Basin. Its coastline has limited geographic shielding from incoming storms.
What is Aurora's worst-case typhoon loss scenario?
At a 100-year return period, roughly a 1% chance in any given year, Aurora could see direct typhoon losses of up to 2.9 billion PHP, equal to about 4.9% of the province's total asset replacement value.
Are typhoons or earthquakes a bigger risk in Aurora?
Typhoons are the larger risk. Aurora's average annual loss from typhoons is about 3 times greater than its average annual loss from earthquakes, 219 million PHP versus 65 million PHP.
How does Aurora compare to other nearby provinces for typhoon risk?
Aurora carries a notably smaller typhoon-related average annual loss than larger neighboring provinces such as Isabela, Nueva Ecija, and Quezon, largely reflecting its smaller total asset base rather than a lower storm frequency.
What percentage of Aurora's assets are at risk from typhoons?
Aurora's total asset replacement value is about 59 billion PHP, of which 77% (45 billion PHP) is private property and 23% (14 billion PHP) is public infrastructure. At a 100-year return period, modeled typhoon losses could reach about 4.9% of that total value.
