Building (216.3 km WNW of epicenter) [Map] / Very weak shaking (MMI II) : I was sitting semi-indian style in my chair with my other knee leaning on my table, the table backed up to the wall. It was impossible for the chair to just be the only one wobbly. I felt the whole room shake side to side, similar to my previous experience. But it was subtle and lasted for 5-6 seconds. I froze on the spot, and felt the whole building moving. | One user found this interesting.  
Zamboanga City / Light shaking (MMI IV) / single vertical bump / very short (reported through our app)
