RE: Earthquake

[Subject Prev][Subject Next][Thread Prev][Thread Next]

My wife is from Hawaii, when I brought her back to California, she experienced her first earthquake.  The earthquake’s magnitude was around 4 or 5 that was located within 30 miles from my house.  She jumped out of bed screaming waking me up.  I got up, asked her if the house is still standing and went back to bed.  Growing up in California is a typical thing that you feel at least a good one every 5 years.  I guess this is one of the reasons I got into this business.


I hope people that did experience the earthquake this morning are doing fine.

You say that "6-point-somethings are pretty common" -- which they are -- "and usually imperceptible" -- which they definitely are not, at least near the epicenter.  From the link that Neil Moore posted (, it is clear that their was quite a bit of non-structural damage (shelves emptied, etc.) and some structural damage.  In October 2005, there was a magnitude 6.7 earthquake on the Big Island of Hawaii which shook up the island of Oahu about 100 miles away.  Not much structural damage resulted, but it raised a few heartrates (mine included).  The power was out island-wide for most of the day.

I think every engineer that does seismic design should have the opportunity to experience an earthquake at least once -- it can definitely bring some perspective to why you're doing what you're doing.

My wife who is studying geography showed me the USGS site yesterday that lists the latest earthquakes in the world for the past 7 days.

I was surprised to discover that 6-point-somethings are pretty common and usually imperceptible.
