Stonehenge Theories
Stonehenge.
Roger Ressmeyer / Corbis
For a set of craggy rocks in an English field, Stonehenge’s ability to capture the imagination is impressive. The ancient monument — composed of massive stones arranged into concentric circles by unknown builders — is referenced almost as far back the Norman Conquest, when an English historian remarked in 1130 A.D. that “no one can conceive how such great stones have been so raised aloft, or why they were built here.” That certainly hasn’t kept many from trying. It seems like everyone has a theory for why the ruins were constructed. Some are more plausible than others.

July 1 Solar Eclipse Data
Partial Solar Eclipse of July 01
Just one lunation after the previous one, the third solar eclipse of the year takes place at the Moon’s descending node in western Gemini. This Southern Hemisphere event is visible from a D-shaped region in the Antarctic Ocean south of Africa (Figure 4). Such a remote and isolated path means that it may very well turn out to be the solar eclipse that nobody sees. At greatest eclipse (08:38:23 UT), the magnitude is just 0.097.

Solar Storm Warning
STORM WARNING: A fast-moving stream of solar wind is buffeting Earth’s magnetic field. The combined effect of this stream plus a CME expected to arrive on June 24th has prompted NOAA forecasters to declare a 30% to 35% chance of geomagnetic storms during the next 24 hours. High-latitude sky watchers should be alert for auroras.

The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian’s Global Volcanism Program and the US Geological Survey’s Volcano Hazards Program.
Updated by 2300 UTC every Wednesday, notices of volcanic activity posted on these pages are preliminary and subject to change as events are studied in more detail. This is not a comprehensive list of all of Earth’s volcanoes erupting during the week, but rather a summary of activity at volcanoes that meet criteria discussed in detail in the “Criteria and Disclaimers” section. Carefully reviewed, detailed reports on various volcanoes are published monthly in the Bulletin of the Global Volcanism Network.

Large Alaskan Earthquake
Massive (scary) Alaskan earthquake in an unpopulated area
Last update: June 24, 2011 at 10:26 am by By Armand Vervaeck and James Daniell 2 Comments
Earthquake summary : A terrifying strong earthquake occurred at 6:09 PM near the remote Alaskan Aleutian Islands. The epicenter of the earthquake was on top of the subduction slope. The energy of this massive earthquake was weakened due to the depth of the epicenter. There was never a widespread Tsunami danger for this earthquake. To read the full story as it happened, we advise our readers to start at the bottom of the page (earthquake data) and to continue going up.
UPDATE 08:45 UTC : We thought it may be interesting for our readers to show how the Alaskan plate tectonics work. The star is the epicenter of the earthquake. Map screen shot courtesy Google Earth.
The Pacific plate is subducting the North American plate by 70 to 80 mm a year!!
