Earthquakes and Volcanoes

Last time we felt a small earthquake at work I dug up some resources. Well, we felt another one this morning:

In the last 24 28 minutes, there have been at least 21 29 earthquakes on the San Andreas fault about 135 miles south-east of where I work. The strongest had a magnitude of 5.9. Another was 5.0, with the remainder between 1.9 and 4.7… They’re all within a few miles of Parkfield California.

It’s interesting to note that there has been up to One or Two Quakes a Minute in Washington where Rumbling at Mount St. Helens Triggers Alert:

Seismic activity at Mount St. Helens has changed significantly during the past 24 hours and the changes make us believe that there is an increased likelihood of a hazardous event

Meanwhile, about 150km north-west of Tokyo, Mt Asama erupted again on Thurdsay after burst back into life earlier this month in its biggest eruption in 21 years.

Check out the global seismic monitor to remember that disasters aren’t always man made.
