The following volcanoes have either been raised in alert level or have maintained their alert status over the last 72 hours.

The four-tiered Volcano Alert Level uses the terms: Normal, Advisory, Watch, Warning. The Volcano Alert Levels are intended to inform people on the ground about a volcano's status and are issued in conjunction with the Aviation Color Code. Notifications are issued for both increasing and decreasing volcanic activity and are accompanied by text with details about the nature of the unrest or eruption and about potential or current hazards and likely outcomes.

 

Alert Level=Normal Aviation Color Code=Green

 

Alert Level=Advisory Aviation Color Code=Yellow

 

Alert Level=Watch Aviation Color Code=Orange

 

Alert Level=Warning Aviation Color Code=Red

 

'Cumbal' (Columbia) - Variable amounts of gas emissions, mostly steam, were observed in the web camera located in Cumbal town (9 km SE) during periods of clear weather, which occurred during 20-21 July. The emissions originated from fumarolic fields located in the main crater on the NE side of Cumbal and Mundo Nuevo crater on the SW side.

'Galeras' (Columbia) - Gas emissions, observed by a network of video cameras, contained ash almost daily. Sulfur dioxide levels fluctuated. On 18 July observatory staff working near the crater reported a strong sulfur odor and fine ash falling on the upper N flank. Ashfall was also reported to the N in the Quebrada Maragato area.

'Ijen' (Eastern Java) - Although weather conditions at Ijen often prevented views of the volcano during 1-24 July, white plumes were occasionally observed rising 50-100 m above the crater. Seismicity indicated unrest, and along with visual observations, prompted CVGHM to raise the Alert Level to Orange.

'Batu Tara' (Indonesia) - Based on analyses of satellite imagery, the Darwin Volcanic Ash Advisory Center (VAAC) reported that ash plumes from Batu Tara rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted 45 km W during 22-23 July and 110 km N and NW on 24 July. Alert Level Orange.

'Cleveland' (Alaska) - Elevated surface temperatures from Cleveland were detected in satellite images during 18-20 July. Images revealed nothing unusual during 20-22 July. Cloud cover mostly prevented observations during 22-24 July; a steam plume rose from the crater on 23 July. The Volcano Alert Level Orange.

'Nevado Del Ruiz' (Colombia) - The Observatorio Vulcanológico and Sismológico de Manizales reported that during 22-24 July low levels of tremor were detected at Nevado del Ruiz, possibly associated with continuing gas and ash emissions. Satellite imagery and ground-based observations on 22 July showed high levels of sulfur dioxide emissions. The Alert Level Orange -  "eruption likely within days or weeks".

Popocatepetl (Mexico) - During 18-23 July seismicity at Popocatépetl indicated continuing gas-and-ash emissions; cloud cover prevented observations during most of this period. Incandescence from the crater was periodically observed and sometimes increased with accompanying emissions. A steam-and-gas plume rose from the crater on 19 and 24 July, and ash-and-gas plumes were observed on 20 and 22 July. Activity increased for a period during 20-21 July; incandescent tephra was ejected 500 m above the crater and ashfall was reported in Ozumba (18 km W). The Alert Level Yellow.

 

Hidden Rift Discovered Beneath West Antarctica

Scientists have discovered a one mile deep rift valley hidden beneath the ice in West Antarctica, which they believe is contributing to ice loss from this part of the continent. Where there are rifts, there are mountains. Where there are mountains, there are volcanoes. Where there are volcanoes, there is the warming of oceans.

When the Earth's core heats up, mostly due to gravity and magnetic flux, it produces magma which finds its way via channels to the Earth's mantle. As a result of this process, ocean waters will warm. The West Antarctica rift (or trench) now known as the Ferrigno Rift - is most likely the source of this regions ice melt. One could surmise a direct correlation between the Sun's solar cycles and increased or decreased submarine volcano activity.
