Quake 3 & 4

We had another shaker a 5.9 this time!  There were only four kids with me when it happened.  We were doing our morning routine when I felt the tremor.  At first it is hard to tell when an earthquake is coming on.  The ground trembles a bit and then there is a train-like sound.  The vibration isn't immediately noticeable as most buildings have a bit of a bounce to the floors here.  The kids didn't catch on until I moved them away from the back of the room to the doorway.  You never can tell what strength it will be but you can identify the direction.  This was quake three today.  Quake two must have happened on my walk to school, I didn't feel a thing.

I filled two containers with water then added blue tempera paint to help us detect earthquakes.  Most times it is too tough to determine if a shake is from kids walking down the hall or an earthquake.  Small ripple = normal.  Large ripple that continues= a shaker.  This may sound like a bizarre thing to do but it really helps to know when to get the kids moving before the real tremors start (ceiling beams moving back and forth and glass rattling).  I used to take a glance at my water bottle but had to stop when I replaced it with an aluminum one.
