 A magnitude 5.7 earthquake has killed at least 13 people and injured 203 in northern Tanzania, the authorities say. 
 
 The quake struck close to the border with Uganda and Rwanda near Lake Victoria. 
 
 Images posted on social media showed significant damage to buildings in Bukoba, a city of more than 70,000 people where most casualties were reported. 
 
 Tremors were felt as far away as western Kenya. 
 
 "This incident has caused a lot of damage," Deodatus Kinawila, the district commissioner of Bukoba, told the BBC. 
 
 "For now, the situation is calm and under control," he said later.

 "Some people have been discharged from hospital," he added. "We don't expect many more injuries." 
 
 The US Geological Survey says the quake struck at a depth of 10km (six miles) at 15:27 local time on Saturday (12:27 GMT). 
 
 East Africa's Great Rift Valley runs along a geological fault line but major earthquakes there are rare. 
 
 A magnitude six quake struck the Tanzanian town of Arusha, east of Bukoba, in July 2007. ||||| BUKOBA, Tanzania, Sept. 10 (UPI) -- Officials said 11 people were killed and 192 injured after a 5.7-magnitude earthquake struck in northern Tanzania on Saturday. 
 
 The quake struck near the western shore of Lake Victoria outside in the city of Bukoba, population 70,000, where a majority of the casualties were reported. Photos posted on social media in Bukoba showed buildings collapsed.

 Local police said hospitals have been overrun with injured people and rescue efforts are under way to help people trapped beneath the rubble of collapsed structures. 
 
 The U.S. Geological Survey said the quake could be felt as far away as western Kenya and was unusually strong for the region. 
 
 "This incident has caused a lot of damage," Deodatus Kinawila, the district commissioner of Bukoba, told the BBC. "As we speak now, the number of injuries stands at 192 and 11 dead. Because we are still collecting the information it's likely to go up. Even the number of injuries is likely to go up." 
 
 The quake occurred at a depth of 6 miles and was recorded at 3:27 p.m., local time. ||||| DAR ES SALAAM, Tanzania (AP) — A 5.7-magnitude earthquake shook the Lake Victoria region of East Africa on Saturday, killing at least 11 people in Tanzania, a police official said. The country's president said that many were dead. 
 
 The quake was felt as far away as western Kenya and parts of Uganda, which share the waters of Lake Victoria. Tremors were also felt in Kigali, Rwanda. 
 
 The 11 who died in Tanzania were in brick structures in the town of Bukoba, said Augustine Olomi, regional police commander for the Kagera region. 
 
 A statement from the Tanzanian president's office said that he was "shocked by reports of the earthquake that caused the death of many people, injury to others and destruction of property." 
 
 The statement didn't provide specific figures on casualties. 
 
 Saturday's quake was shallow, occurring at a depth of 10 kilometers (six miles). Shallow quakes generally tend to be more damaging than deeper quakes. Seismic waves from deep quakes have to travel farther to the surface, losing energy along the way, while the shaking from shallow quakes is more intense. 
 
 Recent earthquakes in the area have caused secondary hazards such as landslides. The last notable quake in the region was in 2004 and measured 4.7.
– Eleven people have been confirmed killed in a 5.7-magnitude earthquake that struck Tanzania Saturday afternoon, but the actual death toll is feared to be much higher, the BBC reports. According to UPI, the earthquake—which the US Geological Survey says was "unusually strong" for the area—struck shortly before 3:30pm local time near Lake Victoria on the border with Rwanda and Uganda. The shallow quake originated only 6 miles below the surface, the AP reports. Shallow quakes typically cause more damage. The city of Bukoba, with a population of 70,000, appears to have been the hardest hit. Photos of collapsed buildings in the city were posted to social media, and the quake's 11 confirmed casualties were people in brick structures in Bukoba when the quake struck. Authorities say 192 people have been confirmed injured in addition to the deaths, but one one authority tells the BBC both numbers are "likely to go up." Local hospitals are already full and having difficulty dealing with the waves of injured.
