Mayon volcano erupts for the second straight day Tuesday, Jan. 23, 2018 as seen from Legazpi city, Albay province, southeast of Manila, Philippines. The Philippines' most active volcano ejected a huge column of lava fragments, ash and smoke in another thunderous explosion at dawn Tuesday, sending thousands of villagers back to evacuation centers and prompting a warning that a violent eruption may be imminent.
