Magnitude 6.8 Quake Strikes Ryukyu Islands, Japan
FEWW Moderators had predicted more powerful earthquakes in the region last week, and now believe as many as 10 additional magnitude 6+ quakes could yet strike the region in coming weeks
Volcanic Activity Forecast
FEWW Moderators also believe there is a strong probability (0.8+) that the submarine Unnamed Volcano located East of Taiwan at 24.00N, 121.83E could erupt in 2009. [See previous comment.]

Volcano near Taiwan’s capital still active, scientists warn

TAIPEI, Novr 2 (AFP) – A volcano overlooking Taiwan’s capital Taipei is still active, and not dormant as long thought, potentially threatening an area that is home to three million people, local media reported Monday.
Datun Mountain, around an hour’s drive from Taipei’s city centre, could devastate the entire urban area if it were to erupt now, the China Post said, citing Academia Sinica, the island’s main scientific institution.
The assessment is based on findings from the academy suggesting the volcano last erupted 5,000 years ago rather than 200,000 years ago, as previously thought, according to the report.
Scientists arrived at the revised date after analysing volcanic ash near the mountain. A final study is expected at the end of the year, the paper said.
An active volcano is defined as one that has erupted within the past 10,000 years, according to the Smithsonian Institution’s Global Volcanism Programme.
Taipei Mayor Hau Lung-bin said he would consider the new findings and set up contingency plans for a possible eruption, according to the paper.
Academia Sinica was not immediately available for comment when contacted by AFP Monday.

Another EQ Heavily Downgraded by USGS
FEWW Moderators note that an earthquake which occurred SE of Lambasa, Vanua Levu, Fiji, this morning (local time), reported as USGS ID: us2009kjcd, was later downgraded from 5.9 to 5.0Mw, a very large margin of error, indeed.
While they have provided invaluable service to geophysics and earth-related sciences previously, USGS Earthquake Hazard Program Data can no longer be relied upon as reasonably accurate.
Either the Program is manned by totally unprofessional individual(s) who are unable to get the initial readings right, or it’s supervised by politically motivated, special-interest “euphimist(s)” who intentionally downgrade the details.
