Earthquake Monitoring
Earthquakes are happening around the world all the time, we just can't feel all of them. The US Geological Survey (USGS) is constantly monitoring the Earth with sensitive instruments and for some time now has offered ways of sharing their data on the web through their Earthquake Hazards Program. In addition to RSS feeds, they introduced Google Earth KML network links which allow you to continuously monitor the status of earthquakes around the world. You can zoom in and look at the areas in the detailed satellite or aerial photos of GE. But, since most of the photos in GE are one or more years old, you won't see evidence of that recent quake.
You have two main options off the USGS Earthquake Hazards page, plus a third option I found for just bigger quakes:
- Magnitude 1+ earthquakes, colored by age

- Magnitude 1+ earthquakes, colored by depth

- Magnitude 2.5+ during past 7 days

This is real-time data which can help you determine whether that shaking you felt really was a quake. One Google Earth Community member wrote how he experienced the earthquake data first-hand.

Hey - I live in hudson ohio between Akron and Cleveland and the house just shook - enough to have bottles fell off desk - anyone know what happened? My son was on the internet with some other people and they felt it in Akron too (about 15 miles from us.

Hi Elaine,
There was seismic activity near you according to this USGS earthquake monitoring layer. It says it was 3.2 magnitude. Here is the USGS event record at their web site:

I was wondering if any one could explain to me why i always hear earthquakes coming before the shaking commences (sounds like a very deep slow roar), and why others around me don't?

Does anyone know how I might get a map detailing all the earthquakes that have occurred in the Pacific Basin ("Ring Of Fire") from August 1st to October 1st, 2007? Any and all help would be greatly appreciated!

5.6 earthquake in Alum Rock (near San Jose, CA) has me thinking about the 89 quake again. I remember that there were a lot of little quakes leading up to the big one. It also got me thinking about how to find a house on stable ground. Links to resources here:

There have been some major earthquakes activity´s here in Iceland lately this week, now it´s 20/11 ´07
and there have been constants earthquakes in my town called Selfoss, it´s in south Iceland. We are used to earthquakes and their happening all the time, but we don´t often notice them except when they get a little aggressive, but they never leave any destructions like you see everywhere else in the world and that is because our buildings can withstand them. Iceland is right a bow that giant thing, crack? um.. what u call it in English? I dunno, i think you know what i mean. ^^ Well anyway i was wondering if those earthquake monitors monitor the earthquakes in Iceland? Ive been trying to find it on Google earth but with out any progress :( This site helped me get that monitor thing about Iceland so many thanks mate, very good site and usable. :)

I was just able to use this application to pinpoint the epicentre of a quake that we have just had here in the UK. It happened at 1am GMT and measured about 5.2 on the richter scale. I felt the whole of my office shake, it was really bizarre. I remembered seeing this post ages ago so logged on, downloaded the file showing recent tremors and it was there. It's great when Google Earth is able to interact with real time events and provide such a wealth of info so quickly.

It has been 13 hours since a quake.
there are about 5-12 quakes per day on earth.
We are due, and Alaska should prepare.

As a former Californian, earthquakes don't bother me much. I still keep an eye on them though. The USGS keeps an updated map online. Check out my blog post for more info

I don't know if anyone else is paying attention but if you go to the usgs website an look at the us map displaying recent earthquakes you will see
the west coast covered with quakes and a pattern of quakes forming an arrow pointing right at yellowstone. 2 months ago the arrow was not very well defined but it has been filling in day by day. I don't know why no one is talking about the emplications. if you know anything abour yellowstone and look at that map, it will really get your attention.

Support KML for monitoring of Earthquakes very good!
I think, all seismologists need support it new realtime standart. With http support can also stored more additional params of Earthquakes. KML support this in baloons.
Very good, if also USGS recommend this format to other "Earthquakes" organizations.
Thanks!
