My Way News - Swarm of Earthquakes Detected Off Oregon: "There have been more than 600 quakes over the past 10 days in a basin 150 miles southwest of Newport. The biggest was magnitude 5.4 and two others were more than magnitude 5.0, OSU reported. They have not followed the typical pattern of a major shock followed by a series of diminishing aftershocks, and few have been strong enough to be felt on shore" I check the USGS earthquake monitor and the IRIS monitor as well ... both show a few quakes but nothing close to the numbers mentioned -- they must be very small quakes (<1.0 mag).
The nice thing about the IRIS page is that quakes which have occurred within the last 24 hrs are indicated by red circles in radiate motion which draws your eye to them .... the USGS page is great because it shows earthquakes that have occured in as little as an hour ago! The new quakes are also shown in red.
Both sites use size of their spots/circles to show strength of quake. the IRIS only shows quakes >4 mag.
USGS shows quakes that are mag 1 or greater.

While the USGS does not show a lot of activity along the west coast, however it does show a lot of small quakes in Alaska along the Alutian straights and in the SW states -- in fact I haven't seen this much activity in the lower 48 in the last four years that I've been using the monitors.

There was a HUGE one between Australia and the Antartic though ... almost an M8 (magnitude 8) ... that's pretty significant, but according to the website there isn't expected to be any Tsunamis from it - well at least there won't be one that will effect the US, it didn't say anyting about there being an issue in Australia though.
