Authorities in the Philippine have started evacuating about 50,000 people from around the country's most active volcano as it spewed burning mud and rocks. Mayon volcano, in a coconut-growing region of the central Philippines, started to release lava early this week and vulcanologists are expecting a major eruption in the next few days.<br/><br/>Officials said the fleeing residents were being temporarily housed in school buildings and public gymnasiums, where local government officials set up food and relief centres. <br/><br/>The last time Mayon erupted was in 2006.<br/> <br/>
