News of activity of the Nevado del Ruiz volcano, April 12, 2013, 11:30 (local time)
During this day continues to record the seismic signal of volcanic tremor, associated with the movement of fluids within the volcanic conduits and gas and ash emissions, which has been showing low energy levels.
In the morning it was observed by the webcams located in the area of the volcano, the plume of steam, gases and ash, with an approximate height of 1600 meters above the summit, heading to the northwest of the volcano presenting white, but with the presence of particulate matter (ash) See animation. There have been several reports from yesterday, officials from the National Natural Park Los Nevados and OVSM, fine ash fall in small amounts in areas surrounding the volcano.
Additionally, continued emissions of sulfur dioxide (SO2), evidenced in measurements of equipment installed in the field and through satellite images.

News of activity of the Nevado del Ruiz volcano, April 14, 2013, 09:00 (local time)


With regard to the monitoring of the activity of the Nevado del Ruiz volcano, the Volcanological and Seismological Observatory of Manizales, reports that:
Continued volcanic tremor logging, seismic signal associated with the movement of fluids within the volcanic conduits and gas and ash emissions, showing low energy levels. From yesterday in the afternoon, this signal has been accompanied by the registration of volcano-tectonic earthquakes, located to the northwest of Arenas crater, at an average depth of 7 km, until the time of issuance of this notice, the largest magnitude earthquake recorded corresponds to at 22:43 (local time) on April 13 with 2.6 ML (local magnitude), felt by officials of Colombia National Parks in the area of Brisas.


During the early morning hours, web cameras installed in the volcano area, allowed to observe a plume of steam, gases and ash, with an approximate height of 630 m measured from the top of the volcano, this column shows white grayish, due to the presence of particulate matter (ash), and is directed towards the northwest along the prevailing wind regime in the area.

Emissions of sulfur dioxide (SO2) are still important as indicated by measurements of field installed equipment and satellite images.

REMAINS THE ACTIVITY LEVEL YELLOW (III): CHANGES IN THE BEHAVIOR OF VOLCANIC ACTIVITY.


With regard to the monitoring of the activity of the Nevado del Ruiz volcano, the Volcanological and Seismological Observatory of Manizales, reports that:

Below is a summary of the activity of the volcano Nevado del Ruiz filed during the last week including the information of the last hours. It is clarified that despite variations in seismic activity remains Amarillo activity level or III. Changes in the behavior of volcanic activity.


Continued seismic activity recorded mainly associated with rock fracturing within the volcanic edifice, located about 6 miles northwest of Arenas crater at depths between 5 and 9 km. The largest magnitude earthquake recorded so far since the beginning of this increased activity on April 13, April 16 occurred today at 07:14 with a magnitude of 3.2 ML (local magnitude). Six of the events of this increase has exceeded magnitude 2.5 ML and some of them have been reported felt by officers of the Los Nevados National Natural Park in the area of Brisas.
Since last April 10 was brought volcanic tremor related to fluid dynamics in volcanic conduits as well as processes of emission and ash.
They continue to experience significant flows of water vapor and sulfur dioxide (SO2) into the atmosphere, evidenced both in the equipment installed in the volcano, as satellite images available. In the morning there was the column of gases and steam, which reached a height of 1000 m above the volcano's summit and presented scattering direction to the southwest of the volcano, following the wind regime in the area.
Continue registering variations in volcanic deformation.
It is reiterated that the move to a higher level of activity is performed when the comprehensive diagnosis of all the volcanic monitoring parameters may suggest...

Activity News Nevado del Ruiz volcano, April 18, 2013, 10:30 (Local Time).


Continued seismic activity recorded primarily related to the fracturing of rock inside the volcano (volcano-tectonic earthquakes or VT), located about 6 miles northwest of Arenas crater at depths from 5 to 9 km. Recall that this increase in type VT seismicity at the volcano began on April 13, and at the time of issuance of this news, the largest magnitude earthquake recorded corresponds to occurred yesterday at 20:45 (local time ) with a magnitude of 4.0 ML, this seismic event was reported as felt by the inhabitants in the area of the volcano, as well as PNNN staff and, of those completing OVSM maintenance and installation of new stations on the volcano , also reached to feel in the municipalities of Murillo (Tolima) and Villamaría (Caldas), as well as in the city of Manizales.

The seismic signal recording volcanic tremor associated with the movement of fluids within the volcanic conduits and gas and ash emissions, still showing low energy levels, and no changes have been reported.

In the morning it was observed by webcams located in the area of the volcano, the plume of steam, gases and ash, with an approximate height of 1000 meters above the summit, heading towards the northwest of the volcano presenting greyish white, possibly indicating the presence of particulate matter (ash). In the current state of the volcano are common emissions of sulfur dioxide (SO2), this compound has a residence time in the atmosphere and mixed with rain water, making it slightly more acidic and sometimes resulting odors sulfur.

Additionally, continue to register variations in volcanic deformation.

The Human Impact of Volcanoes: a Historical Review of Events 1900-2009 and Systematic Literature ReviewApril 16, 2013 · Review

Authors

Shannon Doocy Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, United States. Amy Daniels Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, United States. Shayna Dooling Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, United States. Yuri Gorokhovich Lehman College, City University of New York, New York, United States. Abstract
Introduction.
More than 500 million people live within the potential exposure range of a volcano. The risk of catastrophic losses in future eruptions is significant given population growth, proximities of major cities to volcanoes, and the possibility of larger eruptions. The objectives of this review are to describe the impact of volcanoes on the human population, in terms of mortality, injury, and displacement and, to the extent possible, identify risk factors associated with these outcomes. This is one of five reviews on the human impact of natural disasters.

Methods.
Data on the impact of volcanoes were compiled using two methods, a historical review of volcano events from 1900 to 2009 from multiple databases and a systematic literature review of publications ending in October 2012. Analysis included descriptive statistics and bivariate tests for associations between volcano mortality and characteristics using STATA 11.

Findings.
There were a total of 91,789 deaths (range: 81,703-102,372), 14,068 injuries (range 11,541-17,922), and 4.72 million people affected by volcanic events between 1900 and 2008. Inconsistent reporting suggests this is an underestimate, particularly in terms of numbers injured and affected. The primary causes of mortality in recent volcanic eruptions were ash asphyxiation, thermal injuries from pyroclastic flow, and trauma. Mortality was concentrated with the ten deadliest eruptions accounting for more than 80% of deaths; 84% of fatalities occurred in four locations (the Island of Martinique (France), Colombia, Indonesia, and Guatemala).

Conclusions.
Changes in land use practices and population growth provide a background for increasing risk; in conjunction with increasing urbanization in at risk areas, this poses a challenge for future volcano preparedness and mitigation efforts.

Yellowstone's Volcano Bigger Than Thought
Becky Oskin 17 April 2013

SALT LAKE CITY — Yellowstone's underground volcanic plumbing is bigger and better connected than scientists thought, researchers reported here today (April 17) at the Seismological Society of America's annual meeting.

"We are getting a much better understanding of the volcanic system of Yellowstone," said Jamie Farrell, a seismology graduate student at the University of Utah. "The magma reservoir is at least 50 percent larger than previously imaged."

Knowing the volume of molten magma beneath Yellowstone is important for estimating the size of future eruptions, Farrell told OurAmazingPlanet...

Scientists have updated this image of Yellowstone volcano's underground magma chamber. Instead of two big yellow blobs, they have a clearer picture that looks like a knobby banana.

Lava columns reached 800 m today ( [link to www.meteoweb.eu] ). Volcanic material (lapilli, I suppose, hope not bombs) rained down on western side of the volcano.

Some points from an interview with D. Patanè (INGV):
- very important eruption, about 20-30% more energetic than the last ones
- eruption column up to 10.000 m height
- very fast intensification of eruption
- lava flows til down to bottom of Valle del Bove (I think that is what is still ongoing and seen on the webcams eg. [link to www.lave-volcans.eu] )
- second paroxysm within 48 hours.

My friend Boris Behncke (INGV Catania) indicates that the paroxysm of yesterday April 20th started very suddenly, while the situation was still perfectly calm until 15 p.m., as opposed to April 19th when the SE Crater had experienced explosive activity until evening. Boris says that the lava fountains probably reached 1000 meters high but were often hidden by the curtain of ash and lapilli emitted by the volcano. At the time of climax, Boris was driving on the Messina-Catania motorway near Giarre. He had the good idea to start his camcorder. The video below lets you hear the sound of lapilli on the car and see the vehicles stopped along the road, especially under bridges. Friends who were also in their car in the area told me that the blocks reached 10 cm in diameter.

By clicking on the link below, you’ll see a good video filmed by divers in Hawaii. It perfectly shows the formation of pillow lavas and the collapses due to the accumulation of materials. Such shooting is not without risks as collapses and landslides can occur at any time and underwater visibility is not good in the area where the lava enters the ocean. The risk is also present on the surface because, as I indicated several times, the coastal bench can suddenly disappear into the waters of the Pacific Ocean.

According to a recent study made by scientists of the Université de Savoie in Le Bourget du Lac, France, a previously unknown underground cavity might help trigger the timely eruptions of the famous Old Faithful in YellowstoneNational park. The researchers who uncovered new evidence of a chamber suspect that it stores the pressurized near-boiling water, steam, and other gases that propel Old Faithful’s eruptions...
The French researchers suspect that the cavity they discovered below Old Faithful plays a large role in propelling the geyser’s eruptions and is further evidence supporting the existence of subterranean bubble chambers that fuel geyser eruptions...

A new episode of lava fountaining (paroxysm) has taken place on the afternoon of 20 April 2013 at Etna's New Southeast Crater (NSEC), the 12th event of this type within two months. Explosive activity had resumed on 19 April, less than 24 hours after the end of the previous paroxysm. During the night of 19-20 April, the explosive activity switched to quiet, non-explosive emission of lava from the eruptive fissure at the southeastern base of the NSEC cone, which had opened a the end of the 12 April paroxysm but remained inactive during the subsequent paroxysm on 18 Apeil. During the day of 20 April, effusive activity continued, but explosive phenomena were virtually absent until about 15:00 GMT (=local time -2), when violent explosions started, which rapidly passed into a lava fountain accompanied by the formation of an eruption column. The lava fountains reached heights of 800-1000 m above the crater, whereas the cloud of pyroclastic material expanded toward east-southeast, leading to heavy falls of ash and lapilli over the areas of Zafferana Etnea, Milo, Santa Venerina and further downslope, in the area of Giarre. A well-fed lava flow expanded down the western slope of the Valle del Bove, locally interacting with residual patches of snow, which resulted in the formation of lahars and ground-hugging steam and ash clouds, a phenomenon seen several times during previous paroxysms during the winter season on Etna. Lava fountaining continued for about one hour, and then passed into sporadic explosions and ash emission between 16:15 and 16:25. The episode was essentially over by 16:40, although the lava flow is still showing movement and possibly is still being fed from its source vent (19:00 GMT on 20 April 2013).

A more detailed report will be posted here shortly.

Rumbling Chilean Volcanoes: Laguna del Maule, Lascar, Copahue, Antuco
...Now, over the last few months, seismicity has been on the upswing at Laguna del Maule, with multiple earthquake swarms within the top 10 km of the crust under Laguna del Maule. What is most interesting is the deformation that is being noticed across the area — in the central part of the lake, land is rising at 1.40 cm/month, while on the west side of the lake, the land is rising at 0.64 cm/month. Those might seem like small numbers, but for volcanic deformation, that is high enough to cause the SERNAGEOMIN raise the alert to Yellow (eruption possible in weeks to months) when combined with the increased seismicity.
