color:#1F497D'>I recall that Barbara B did a test with lots of earthquakes, and
the map really bogged down. This test didn't have many quakes on it
(M>2.5). It is absolutely necessary to be able to see quakes down to
M1, because in aftershock sequences they rapidly map out the rupture zone, or
in volcanic sequences indicate changing levels of unrest. In CA, the map is
boring without all of the little quakes. Moreover, many users just want
to see all the quakes, regardless of their motivation. This map interface must
be able to smoothly handle that level of information. For example, on the
CA-NV map today, there are 600 quakes/week. It could easily jump to 3000
quakes during a volcanic sequence. Have things improved since Barbara did
her test?<o:p></o:p></span></p>

<p class=MsoNormal>Below is a link to a proof of concept mapping tool that
plots recent earthquakes on a Google Map using the RSS feed as a data source.
This application isn't perfect but can serve as a starting point for a more
elaborate effort. Please take a moment to look at this tool and also to fill
out the feedback form about it so I can know what people are thinking and how
well the tool is working.<o:p></o:p></p>

<div>
<p class=MsoNormal>Because the RSS feeds aren't being updated on EHPDevel, the
data you see may be out of date, but this is driven dynamically on the client
side so if this goes into production we will automatically get updated mapping
assuming our RSS feeds are working (they should be).<o:p></o:p></p>
