Lava cascades down the slopes of Mayon volcano as seen from Lignon Hill in Legazpi city, Albay province southeast of Manila, Philippines on Tuesday evening Aug. 15, 2006. Mayon continues with its mild explosions with scientists predicting "more pyroclastic flows" will probably occur in the following days due to its progressing explosions. More than 40,000 residents living around the foot of the volcano are now housed in different evacuation centers in the city and nearby towns. (AP Photo/Bullit Marquez)
