On 20 April 1905, a typhoon damaged the Ponape post office. Among the losses were the Ponape canceller and a large number of stamps.
Among the key losses were a stock of 5 Pf stamps, which were a high-demand value. To fill the void, the Ponape post office used bisected 10 Pf stamps cancelled by the old Ponape official seal.
This provisional use ceased on approximately 9 July 1905.
