Jakarta, Sep 2 (DPA) At least 25 people were killed and dozens injured Wednesday when a 7.3-magnitude earthquake rocked Indonesia's Java Island, officials said.

The quake was felt strongly in the capital Jakarta, shaking buildings and sending residents running out of their homes and high-rise office towers in panic.

A tsunami alert was cancelled about 45 minutes later after no giant waves materialised.

'The quake left large cracks in my apartment walls. I'm traumatised,' said Yuni Wahidah, who lives in an apartment building in central Jakarta.

The quake triggered a landslide in a village in the West Java district of Cianjur, killing at least 12 people, said Panji Maulana, an official at the National Agency for Disaster Management.

The other 13 fatalities were from Sukabumi, Garut and Tasikmalaya districts, both in West Java, he said.

Panji said he expected the death toll would rise.

'We have problems communicating with the affected areas because of power blackouts,' he said.

Indonesia's state-run Antara news agency reported that 57 people were buried alive in Cianjur after a hill collapsed and hit a number of houses.

Rescue workers, using traditional equipments and lighting with torches were continuing their search for the missing people who were buried under house debris, the report said.

Earlier, the disaster management agency's spokesman Priyadi Kardono said 10 office buildings collapsed in the West Java capital of Bandung but there were no reports of fatalities.

More than 5,000 people sought refuge at government offices in Cianjur because they were too afraid to return home or their houses were damaged, Priyadi said.
