At least 4 significant aftershocks have occurred, as of posting, the largest of which measured 5.5Mw.

Meantime, the authorities evacuated the crippled Fukushima Power Plant, after Tsunami Advisories were issued.

The plant operator said on Saturday there was no damage or change in radiation levels at the station following the quake, according to reports.

A 30cm tsunami reached Japan’s east coast, NHK reported.

The quake reportedly shook buildings far away as Tokyo, about 230 km south of Fukushima nuclear plant, and 475km WSW of the epicenter.

VolcanoWatch Weekly [26 Oct 2009]

FEWW Volcanic Forecast

On April 21, 2009 in Sumatra’s Mt Kerinci Erupts FEWW made the following forecast

FEWW Volcanic Forecast:

1. The Loyalty – New Hebrides  Arc Collision. Intense volcanic activity should be expected throughout 2009 and beyond along the New Hebrides arc, the Vanatu region (also to the north to include Solomon Island and Santa Cruz Island), possibly continued along the New Hebrides Trench (to include Matthew and Hunter Island). Volcanoes that are located in the above-described area include:

• Savo (Solomon Island)
• Tinakula (Santa Cruz Island – SW Pacific)
• Suretamatai
• Motlav
• Gaua
• Mere Lava
• Aoba
• Ambrym
• Lopevi
• Kuwae
• North Vate
• Traitor’s Head
• Yasur
• Eastern Gemini Seamount
• Matthew Island
• Hunter Island

2. Pacific Plate subduction beneath the Okhotsk Plate. Subduction of the Pacific Plate beneath the Okhotsk Plate continues to create Intense volcanism. Starting 2009, however, a much greaterthan the average number of volcanoes located on the Kuril Islands island arc, Kamchatka volcanic arc and Japan trench to the south may erupt with renewed intensity.

And the following on June 5, 2009, having first introduced Mt Kaba earlier on Weekly Volcano Watch: 16 April 2009

FEWW Volcanic Activity Forecast:

FEWW Moderators forecast  new volcanic activity/ unrest at 50 or more volcanoes throughout the rest of 2009.

List of the volcanoes to watch this year [and in 2010] includes:

Barcena (0.8), Socorro (0.8), Curacoa (0.99), Atitlán (0.65), Vesuvius (>0.6), Bazman (0.6), Mount Shasta (>0.5), Kaba (>0.5), Bandai (>0.5), Eastern Gemini Seamount or Mathew Island volcano (0.65), Fonualei (0.65), Mount Rainier (>0.5), Jan Mayen (>0.6), Thule (0.4), Sibayak (>0.5), Volcán Guallatiri (0.65), Taveuni (>0.4),  two or more volcanoes on the island of Hokkaido (0.65), E-san (0.7), Oshima-Oshima (0.7), Komaga-take (0.65)

SI / USGS Weekly Volcanic Activity Report for 14-20 October 2009 listed both  Kaba and Gaua Volcanoes as erupting:

On 13 October, Vanuatu Geohazards Observatory confirmed that Gaua’s Mount Garat was erupting based on fieldwork done by scientists during 3-7 October. Seismic records showed multiple explosions, and a gas flux measurement of 3,000 metric tons of sulfur dioxide was detected on 3 October. The Alert Level was raised to 2 (on a scale of 0-5).

And

On 20 October, CVGHM reported that seismic activity from Kaba increased in August and remained elevated in September and October. Inflation was also detected. When weather permitted, diffuse white plumes were seen rising 25-50 m above the crater rim and drifting E. Based on the deformation and increased seismicity, CVGHN raised the Alert Level to 2 (on a scale of 1-4).

(14 October – 20 October 2009)

New activity/Unrest:

• Chaitén, Southern Chile
