US Volcanoes

Cleveland Watch Orange 2015-09-18

• Low level unrest continues. No significant activity detected in seismic or infrasound (pressure sensor) data. Minor steaming observed in web camera images and slightly elevated surface temperatures detected in satellite data during periods of clear weather over the past week.  Alaska Volcano Observatory (AVO)

Kilauea Watch Orange 2015-09-18

• The lava lake at Kīlauea’s summit remains active. At the East Rift Zone, the lava flow northeast of Puʻu ʻŌʻō remains active within 8 km (5 mi) of the vent and does not currently pose a threat to communities. Normal levels of seismic and deformation activity continue across the volcano.
• Puʻu ʻŌʻō Observations: The multiple vents within Puʻu ʻŌʻō crater continued to outgas and glow at night. The sulfur dioxide emission rate from all East Rift Zone vents was about 400 metric tons per day when measurements were last possible on August 13, 2015. A magnitude 3.8 earthquake that occurred at about 8 km (5 mi) depth SSE of Puʻu ʻŌʻō yesterday afternoon was widely felt on the island. Hawaiian Volcano Observatory (HVO)

Shishaldin Watch Orange 2015-09-18

• Low-level activity within the summit crater of Shishaldin likely continues. Seismicity remains slightly above background levels but no activity observed in satellite data and web camera images during periods of clear weather over the past week. AVO
  

Mauna Loa Advisory Yellow 2015-09-17

• HVO seismic stations continue to record elevated rates of shallow, small-magnitude earthquakes beneath Mauna Loa’s summit, upper Southwest Rift Zone, and west flank.

Pagan Advisory Yellow 2015-09-18 [Northern Mariana Islands]

• Seismic, infrasound, and web camera data from Pagan Volcano remain temporarily unavailable. No activity observed in satellite images during periods of clear weather over the past week. Volcanic gas from Pagan may be noticed downwind of the volcano as a distinctive sulfurous odor.

Ongoing Activity

Kizimen Volcano blew out a plume of ash, smoke and steam over the  Gulf of Kamchatka on February 1, 2011.  Kizimen recent eruptions are said to be both explosive and effusive. This natural-color image was taken by the MODIS aboard the Aqua satellite. Source: NASA-EO. Click images to enlarge.

Kizimen Volcano on Russia’s Kamchatka Peninsula (elev. 8,153 ft/2,485 m: KVERT 13 june 2011),  ejected a plume of ash, steam and volcanic gasses on January 6, 2011, when ALI on NASA’s EO-1 satellite captured this natural-color image.  Kizimen had released continuous ash emissions since December 31, 2010, KVERT reported. Kizimen erupted explosively 83 years ago. Source: NASA-EO.
