M5.9 Quake Strikes Kuril Trench

Posted by feww on November 17, 2015

Strong quake occurs near Zenkavich Rise

Centered at 48.302°N, 154.285°E (about 296km SSW of Severo-Kurilsk), the quake struck at a depth of 34.0 km (21.1 mi), reported USGS/EHP.

The Kuril-Kamchatka Arc is a seismically hyperactive region. In November 5, 1952 a M9.0 event, the 5th largest recorded earthquake in history, generated a devastating tsunami with run-up wave heights measuring about 15, 18 and 12 meters striking along the coast of Paramushir (located in the northern portion of Kuril Islands chain) causing significant damage to many settlements in Sakhalin Oblast and Kamchatka Oblast, and destroying the town of Severo-Kurilsk.

After the earthquake most of the Severo-Kurilsk residents fled to the surrounding hills, and were spared by the first wave. However, many of them returned to the town only to be claimed by the second wave.

The tsunami killed about 2,340 people out of a population of 6,000. The survivors were evacuated to continental Russia, and new settlements were later built in different locations.

Tao-Rusyr Caldera

Posted by feww on October 25, 2009

Tao-Rusyr Caldera, Onekotan Island, Kuril Islands, Kamchatka Peninsula, Russia

Latitude: 49.35°N 49°21’0″N
Longitude: 154.70°E 154°42’0″E

The huge Tao-Rusyr caldera on southern Onekotan Island is one of the most spectacular volcanoes of the Kuril Islands off the southern tip of Russia’s Kamchatka Peninsula.  The 7.5-km-wide caldera was formed about 7500 years ago during a catastrophic volcanic eruption, one of the largest Holocene eruptions in the Kuril Islands. Today, the basaltic-to-andesitic ancient Tao-Rusyr Caldera is filled by the deep blue waters of Kal’tsevoe Lake, whose surface is 400 m above sea level.

A large symmetrical post-caldera cone, 1325-m-high andesitic Krenitzyn Peak, forms a 4-km wide island that towers high above the caldera rim and fills the NW portion of the caldera lake. A 350-m-wide, 100-m-deep crater truncates the peak and a large lateral crater is located on the upper NE side.

The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite acquired this true-color image of southern Onekotan on June 10, 2009. In this late-spring shot, snow or ice lingers on the land, forming white streaks on a brown-and-green land surface. In the northwest quadrant of the caldera is Krenitzyn Peak, which rises to a height of 1,325 meters (4,347 feet).

Like the other Kuril Islands, Onekotan lies along the Pacific Ring of Fire. The Kuril Island volcanoes are fueled by magma generated by the subduction of the Pacific Plate under the Eurasian Plate, which takes place along a deep trench about 200 kilometers (120 miles) to the islands’ east. The only historical eruption at Krenitzyn Peak occurred in 1952, a week after a magnitude 9.0 earthquake along the subduction fault.

Tao-Rusyr Caldera
A large symmetrical post-caldera cone, 1325-m-high Krenitzyn Peak, forms a 4-km wide island that towers above the rim of 7.5-km-wide Tao-Rusyr caldera. A 350-m-wide crater caps the peak, and a large shallow lateral crater (left center) is located on the upper NE flank. The small dark mass along the eastern shoreline (right-center) is a lava dome that was emplaced in 1952 during the only historical eruption of the volcano. Kal’tsevoe lake fills a caldera that was formed about 7500 years ago during one of the largest Holocene eruptions in the Kuril Islands.

Sarychev Peak Before and After Images

Posted by feww on July 5, 2009

Before and after images show impact of  the Sarychev Peak Volcano eruption on Matua Island.

Ostrov Matua, Kuril Islands

Image dated June 30, 2009

Image dated
May 26, 2007

Acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite, these images of Ostrov Matua show the island shortly after the eruption on June 30, 2009 (top), and two years before on May 26, 2007 (bottom).

In these false-color images, vegetation appears red, water appears dark blue, and clouds, water vapor and ice all appear white. Volcanic rock, including old lava flows and debris from the recent eruption, ranges from gray to dark brown.

The most striking difference between these two images is the gray coating on the northwestern half of the island in June 2009. While vegetation on the rest of the island appears lush, volcanic debris—probably a mixture of pyroclastic flows and settled ash—covered virtually all the vegetation on the northwestern end. A close look at the top image also reveals that the recent volcanic activity appears to have expanded the island’s coastline on the northwestern end.

Another difference between the images relates to snow cover. In the image from May 2007, snow spreads over much of the island, although the snow alternates with snow-free ground. The vegetation is pinkish-gray, suggesting the spring thaw is still underway. The complete lack of snow in 2009 may result from a combination of a difference in season and volcanic activity having melted or covered any lingering snow.

How Sarychev Peak Moved from Russia to Japan!

Posted by feww on June 25, 2009

Better late than never mate, goes the Australian saying

As for the reporting accuracy, close but no shrimps!

better late than never mate
Sarychev Volcano moved to Japan (!) See section underlined in red.
A condensed screen dump of the news URL at Australia‘s Melbourne Herald Sun site,21985,25688161-24331,00.html

Even the Aussies should be entitled to accurate, prompt reporting!

Heaven knows we have criticized Earth Observatory often enough for holding on to images of public interest instead of releasing them instantly on Internet.  However it took the Australian broadcaster nearly two weeks and a major political shift, taking the Sarychev Peak out of the hands of Russians and handing it over to the Japanese, to report the eruption.

Sarychev Peak Spews Two Plumes of Ash

Posted by feww on June 14, 2009

In the Majestic Earth’s Service

Sarychev Peak Spews Two Plumes of Ash, Helping to Balance Earth’s Energy Budget

FEWW Moderators believe that Earth is using some of her natural mechanisms to balance her energy budget, which has been forced into red by human activity. Over the coming months, Moderators will explain how the system works.

It’s a balancing act on a planetary level, and there’s a price to pay for using large-scale natural defense mechanisms. They don’t come cheap. Even IF successful on the planetary scale, the “trade-off,” if it can be so crudely termed, would be reflected in further erosion of the earth’s debilitated carrying capacity…

Watch this space for more information!

Activity at Sarychev Peak

Sarychev Peak located in NW end of Matua Island (Ostrov Matua) in Russia’s central Kurils reportedly spewed  ash plumes in two directions, west-northwesterly, and east-southeasterly. NASA’s Aqua satellite using its Moderate Resolution Imaging Spectroradiometer (MODIS) captured this image on June 12, 2009. Thanks to the age of modern technology (!), NASA’s MODIS Rapid Response Team at Goddard Space Flight Center rapidly posted the image on their website in under 48 hours.

Sarychev Peak (Kuril Islands, Russia)

A cloudcap obscurs the dramatic, 250-m-wide, steep-walled summit crater of Sarychev volcano, one of the most active volcanoes of the Kuril Islands. Sarychev occupies the NW end of Matua Island in the central Kurils in this NASA Space Shuttle image (with north to the top). The andesitic central cone was constructed within a mostly buried 3-3.5 km wide caldera; an older volcano forms the SE part of the island (lower right). The substantially higher SE rim forms the 1496 m high point of the island. Fresh-looking lava flows descend all sides of Sarychev Peak. Eruptions have been recorded since the 1760’s and include both quiet lava effusion and violent explosions. The largest historical eruption of Sarychev Peak in 1946 produced pyroclastic flows that reached the sea. The small island of Toporkovyi is partially visible at the right-center.

Tectonic Summary:

The Kuril Islands earthquake of January 15th, 2009 occurred as a result of thrust faulting within the Pacific plate. The event occurred near the outer-rise of the Pacific plate about 30 km to the east of where the Pacific plate subducts beneath the Okhotsk plate. In this region, the Pacific plate moves northwest with respect to the Okhotsk plate with a velocity of about 90 mm/yr.

Large and great earthquakes are not uncommon in this region. The location of this event is approximately 90 km to the northeast of the Mw 8.1 outer rise earthquake of January 13th 2007, which occurred as a result of normal faulting near the Pacific plate outer-rise. On November 15th 2006, an Mw 8.3 subduction-related thrust earthquake occurred approximately 160km to the southwest. [Source: USGS]

Tsunami Warning:
NO destructive Pacific-wide tsunami is expected.
