President Gloria Arroyo placed the Philippines under a "state of calamity" today and terrified people fled their homes as a powerful typhoon threatened to unleash more carnage following deadly floods.

After being accused of not preparing her country adequately for last Saturday’s storm that killed 293 people in and around Manila, Ms Arroyo also ordered forced evacuations of towns in the direct path of Typhoon Parma.

‘‘The prediction is that this typhoon is very strong. Our prayers are that no lives will be lost,’’ said Bella Angara, the governor of the northern Philippine province of Aurora which is predicted to feel Parma’s full force.

The government warned Parma would tear down houses, while likely bringing more heavy rain to the nation’s capital, Manila, and nearby areas that were still recovering from last Saturday’s record floods.

‘‘We’re praying very hard that the super typhoon will spare us,’’ said housewife Nita Solita, 42, who was living in a makeshift evacuation centre in Manila after losing her home in the floods.
