After the M6.7 Northridge Earthquake in 1994, thousands of aftershocks kept everybody's nerves on edge for months. All this time, seismologists on TV were beaming like kids with a new toy, saying, "Boy, we sure learned a lot from this one! We didn't even know that fault was there! For all we know, that may have just been a foreshock of an even bigger one!!!"
Our San Fernando Valley firm had a branch office in Palmdale. Under normal circumstances it was a 50-minute drive between offices, but after the quake destroyed freeway interchanges it was a 3+hour ordeal each way. So I made use of rented airplanes to shuttle files and office equipment back and forth from Van Nuys to Lancaster.
A couple of weeks after the main quake I was taxiing out at KVNY in a rented Saratoga just as a sharp M4.1 aftershock hit. As described in an earlier post, it felt like a flat tire. But realizing what it was, I keyed the mic and called KVNY ground, "37 Kilo would like to file a pilot report for moderate turbulence on the east taxiway ... "
The main quake knocked out the windows of the Van Nuys tower cab. I heard a pilot carrying relief supplies say to ground control, "You guys need anything? I got bottled water and disposable diapers." Ground control replied, "Thanks. We have plenty of water but I think we could use the diapers!"
I heard a radio station's helicopter traffic reporter describe the scene when the main quake hit in the pre-dawn hours. He said street lights were moving in discernable waves as far as he could see. A Southern Pacific railroad engineer said he could see the rails moving in a wave toward him, as if someone had whipped a garden hose up and down (the 400,000-pound locomotive wound up on its side).
With each aftershock plumes of dust would come up from the canyons and hills surrounding the Valley, looking like someone had slapped a dusty sofa ...
It was a scary time. And by all accounts there was no comparison between the Northridge quake and what the folks in Japan have been through. Prayers for them.
