JAKARTA, Nov 25 (Reuters) An earthquake measuring 6.8 hit off the coast of Indonesia's Sumbawa island, the country's meteorological agency said -- the second such tremor in the area with hours.
The quake hit 48 km northwest of Raba in Sumbawa, at a depth of 45 km, the agency said in a text message, and issued a tsunami warning.
Late today evening, an earthquake measuring 6.7 hit in the same area.
An earthquake measuring 6.0 also hit off the coast of Sumatra island, the meteorological agency said.
The quake hit 107 km (66 miles) southwest of Mukomuko in Bengkulu, Sumatra at a depth of 20 km (12 miles), the agency said in a text message. There was no tsunami warning.
Today a quake with a 6.2 magnitude hit the same area.

Indonesia, which is situated in a belt of intense seismic activity known as the ''Pacific Ring of Fire'', was hit by a huge earthquake in December 2004, triggering a devastating tsunami in the Indian Ocean, which killed more than 230,000 people in the region, including 170,000 Indonesians.
