KATHMANDU An earthquake measuring 4.3 on the Richter scale shook parts of west Nepal on Tuesday, the National Seismological Center said.

There was no immediate word on any damage or casualties, authorities said.

The Seismological Center said the epicenter of the tremor that struck at 9 a.m. (0315 GMT) was at Dhaulichour in the Bajhang district, 500km (312 miles) west of Kathmandu.

Last month, two quakes jolted Nepal. One quake, which measured 4.4 on the Richter scale, hit the Bajura district about 425km (265 miles) west of Kathmandu. The other, registering 4.8 on the Richter scale, hit central Nepal.
