By Manuel Mogato and Roli Ng TACLOBAN, Philippines (Reuters) - Dazed survivors begged for help and scavenged for food, water and medicine on Monday after a super typhoon killed an estimated 10,0000 in the central Philippines. President Benigno Aquino declared a state of national calamity and deployed hundreds of soldiers in the coastal city of Tacloban to quell looting. One of the most powerful storms ever recorded, typhoon Haiyan leveled Basey, a seaside town in Samar province about 10 km (6 miles) across a bay from Tacloban in Leyte province, where at least 10,000 people were killed, according to officials. About 2,000 people were missing in Basey, said the governor of Samar province.
