The Taal Volcano, about 37 miles south of Manila on the island of Luzon, erupted in the afternoon, forcing residents to evacuate as experts warned that another "hazardous explosive eruption" is possible.

"We were actually nervous because while working we kept on checking social media for updates on the volcanic eruption. So we were actually aware of the warnings and escalating levels that was being announced real time," Evan told CNN.

"We also discussed discreetly among ourselves what we should do when worst comes to worst."
