Earthquake Activity Time Animation

This week I am attending the American Geophysical Union (AGU) fall meeting. Over 10,000 scientists from around the world attend this event in San Francisco each year. There are thousands of presentations and poster sessions discussing a broad range of topics on geology, atmospheric sciences, marine science, hydrology, etc. I will be reporting on several presentations and poster presentations regarding the use of virtual globes for science applications over the next few days.
Yesterday, I was talking to a scientist at the USGS about their Earthquake Monitoring tool for Google Earth. Although their tool has not changed much since it was originally made available, it still serves as an excellent example of showing near-real-time data of global science data in a meaningful way to the public. I did suggest they should consider creating a time animation in GE showing the progression of seismic activity over the course of many days. Today I just remembered, I had found an example by ‘giasen’ who did this and posted it at the Google Earth Community. He created this time animation which shows: “Latest Earthquakes Magnitude 2.5 or Greater in the United States and Adjacent Area sand Magnitude 4.0 or Greater in the Rest of the World – Last 7 days”. Based on data from the USGS here. I suggest clicking on the little clock icon to the left of the time slider and selecting “Clamp beginning of time window” so you can see the progression of the earthquakes. I’d like to see the USGS create KML files for several variations of their data for time animations like these.

    Speaking of time animation and the time slider, I think the possibility to enter the desired beginning and ending of the span of the slider should be add, let’s say when you double-click on it.
    It would allow greater flexibility, especially when the time span of the data set is long. It would allow one to go to a specific time.
    Thank you for the post
