At least 15 people have been killed, and over 50 houses and buildings were damaged after a 7.3- magnitude quake rocked Indonesia on Wednesday, the country's Disaster Management Agency and Meteorology Agency said. Spokesperson of the disaster management agency Priyadi Kardono told Xinhua that the 15 killed included four deaths in Tasikmalaya regency, 10 in Cianjur and one in Sukabumi of West Java province. The quake damaged 33 houses, and 25 of them suffered from serious damages, he said. Ten office buildings collapsed in Kota Bandung of the province, and four houses were also collapsed in Garut of the province, Kardono said. A 7.3 magnitude earthquake struck western parts of Indonesia on Wednesday, causing panic in some cities and potential for tsunami, but the issuing of tsunami was later canceled. The quake struck at 14:55 p.m. Jakarta time (0755 GMT) with the epicenter at 142 km southwest of Tasik Malaya of West Java and at a depth of 30 km, the meteorology agency said. Indonesia, with over 230 million people, sits on a vulnerable quake-hit zone so called the Pacific Ring of Fire, where two continental plates meet causing frequent seismic and volcanic movements.
