The United States Geological Survey (USGS) has an excellent Earthquake Center for all the earthquakes in the world, which is very handy at a time when many are happening at once, followed in some cases by tsunamis that cross seas to strike coastlines minutes to hours later.
For example, this list of earthquakes of magnitude 5 and greater shows in red both the 8.0 quake that caused tsunamis in the South Pacific, and the 7.6 quake that devastated western Sumatra and also poses a serious tsunami risk — both just in the last few hours. Tonga alone has seen thirteen aftershocks of 5.0 or greater. The Samoa Islands Region has seen twelve.
Bear in mind that the Loma Prieta Quake in 1989 was around a 7.0, and 5.0 earthquakes have caused thousands of deaths as well.
Most of us are great distances from both regions that were just hit, but we are still in position to help. One way is by getting facts straight, and also to keep fail whales from falling on lines that are bound to be congested. Hope this little bit of pointage helps.

Pretty sure the two biggies were 24 hours apart. The red you see over the 8.0 Samoan quake is a newer aftershock in the 5+ range. And the hits just keep on coming…
