Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Sarychev Peak Spews Two Plumes of Ash

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…

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.
