Earthquake at Lishen

Today we went on a field trip to Lishen battery factory in the morning. Lishen is the largest battery manufacturer in China and is the 5th largest in the world. I thoroughly enjoyed our tour of Lishen, which was done by the vice president of the company, which I thought was pretty awesome. At the end of the tour of the factory, he (Kevin) brought us into the conference room for an informational presentation. During the middle of the presentation, the table and walls started to shake. At first, I thought it was Dahui shaking the table to wake someone up. Then I realized the wall was shaking as well, and knew that that was not the case. My second though was that it was just some machinery in the factory or something. Everyone in the room who noticed the shaking (a few didnt notice at all) were dumbfounded, until Dahui and others confirmed that it was in fact an earthquake. It only lasted about 3 seconds and wasn't very intense but it was awesome. I"m glad it wasn't any more serious than that though.I found out later in the day that the earthquake registered at approximately 4.8 on the richter scale in a city a few hours for Tianjin. I thought it was very weird that we felt this aftershock so far from where the actual earthquake took place. I also talked to others about their whereabouts during the earthquake and found it funny that one of them was in bed while it happened. Overall, I am glad no one we were with was hurt or affected and I am happy that I got to experience my first ever earthquake in China!
