FACTS:

Eduave  owned  a  parcel  of  land  which  later  was  eroded  due  to  a  typhoon and through the movement of land deposit.  Eduave granted defendants to plant  corn  and  bananas.    She  also  hired  a  surveyor  to  put  monuments.  
She  also  paid  taxes.    Here  comes  petitioner  who  opposes  the  claim  of ownership claiming the typhoon caused the formation of island, the same they occupied for 15 years now.   
 

HELD:

The  island  formed  belongs  to  the  owner  of  the  land  with  the  nearest margin.
 
If the riparian owner fails to assert his claim, it could be open to adverse possession.
