27 May 2011 - Imminent Erupt - Costa Rica - Cordillera Central, Poas Volcano
Event: VA-20110527-30906-CRI Activity at the Volcano Poas is increasing rapidly, while at the same time drying up the lagoon, say experts, a team of geologists and volcanologists from the seismological network of the Universidad de Costa Rica (UCR). The team visited the colossus on Wednesday where the recorded 18 "phreatic eruptions" in a three hour period, when normal is 1 or 2 per day. The temperature of the crater is also increasing, which is causing the lagoon to dry up and possibly disappear. Experts warn that this could bring more acid rain and ash in the area around the volcano. However, the activity of Poas is not a danger to tourists and the national park will continue open. A phreatic eruption, also called a phreatic explosion or ultravulcanian eruption, occurs when rising magma makes contact with ground or surface water. The extreme temperature of the magma (anywhere from 600 to 1170 °C (1112 to 2138 °F)) causes near-instantaneous evaporation to steam resulting in an explosion of steam, water, ash, rock, and volcanic bombs. At Mount St. Helens, hundreds of steam explosions preceded a 1980 plinian eruption of the volcano.A less intense geothermal event may result in a mud volcano. In 1949, Thomas Jaggar described this type of activity as a steam-blast eruption. Phreatic eruptions typically include steam and rock fragments; the inclusion of lava is unusual. The temperature of the fragments can range from cold to incandescent. If molten material is included, the <b>...</b>

Written and Produced by Donald B MacGowan Narrated by Frank Burgess Video and Still Photography by Donnie MacGowan and Frank Burgess The Kilauea Overlook gives a breathtaking view of Kilauea Caldera and Halema'uma'u Crater. Rarely crowded as it's not on the scheduled stops of the tour buses, this is a nice, quiet place to sit and contemplate the awesome power of Madame Pele. Look around the area between the parking lot and the crater. Those enormous boulders were cast up out of Kilauea and Halema'uma'u craters during explosive eruptions. Nothing speaks so eloquently to the power and violence of the occasional phreatic (driven by steam from groundwater contact with the hot magma) eruptions of Kilauea as these boulders scattered about the landscape. If you turn your back to the crater and look due north, on a clear day, you can see Mauna Kea peeking over the shoulder of Mauna Loa. Many days you can even make out the astronomical observatories on the summit; after dark you can see headlights of cars winding their tortuous way down the mountainside. A covered picnic shelter and restrooms are also available. No water is available.

Magnesium is vitally important and needs to be taken on a daily basis; everybody should take it, because food today is low in magnesium. The reason for that is very simple: plants need very much magnesium to breath. Their chlorophyllic mechanism is fixation of carbonic gas and elimination of oxygen, which is the opposite of what we do. We do this through a mineral, iron is used for the breathing mechanism of red cells. In plants this is done by chlorophyll whose structure is basically magnesium. What happens is that the chemical fertiliser used today is the NPK, nitrogen, phosphorus and potassium. Magnesium in not being replaced in the soil, and in the past, when cities were all made up of houses with septic tanks, the magnesium we eliminated through feces went back to the phreatic zone. However, today everything goes into the rivers and sea, resulting in an increasingly low rate of magnesium in the soil. The two most important functions of magnesium are: it regulates the metabolism of calcium in the body, it fixates the calcium where it should be and eliminates the calcium where it should not be. Therefore, spinal calcifications, joint, artery calcifications happen due to this lack of magnesium. Kidney calcifications, calcium oxalate kidney stones is due to a lack of magnesium. It is enough to give patients magnesium to dissolve kidney stones, provided they are not urate and phosphate ones. if they are calcium oxalate stones then they are due to lack of magnesium <b>...</b>

The reason is very simple, being that plants greatly need magnesium in order to breathe.

What happens is that the chemical fertiliser used nowadays is NPK - nitrogen, phosphorus and potassium. Magnesium in the earth is not being replaced.

KELIMUTU TIWU TELU
Kelimutu is a volcano, close to the town of Moni in central Flores Island of Indonesia containing three summit crater lakes of varying colors. Tiwu Ata Mbupu (Lake of Old People) is usually blue and is the westernmost of the three lakes. The other two lakes, Tiwu Nuwa Muri Koo Fai (Lake of Young Men and Maidens) and Tiwu Ata Polo (Bewitched or Enchanted Lake) are separated by a shared crater wall and are typically green or red in color, respectively. The lake colors do vary on a periodic basis. Subaqueous fumaroles are the probable cause of active upwelling that occurs at the two eastern lakes. The lake have been a source of minor phreatic eruptions in historical time. The summit of the compound 1639-m-high Kelimutu volcano is elongated two km in a WNW-ESE direction; the older cones of Kelido and Kelibara are located respectively three km to the north and two km to the south. The scenic lakes are a popular tourist destination.

The film also showes an excursion to Etna´s summit craters. Note the degassing activity at Bocca Nova crater. About two weeks after this video was made, it was sight of a catastrophic phreatic explosion. About 200 tourists were in this area at this time. Nine people were killed and more than twenty seriously injured. Also an emergency car was hit by a bomb, causing a gas cylinder to explode, burning nearby tourists.

In March 1980 magma underneath Mt. St. Helens began pushing toward the surface. This initially caused earthquakes and phreatic eruptions (groundwater turning into steam as the surrounding rocks are themselves heated by the new magma). Over the course of a few months St. Helens' north flank also bulged considerably.

The scenic lakes are a popular tourist destination. Keli Mutu is also of interest to geologists because the three lakes are different colors yet reside at the crest of the same volcano [2]. According to the local officer at Kelimutu National Park, the colour changed by chemical reaction of any minerals contained in the lake in triggered by volcano gas activity. The closest airports are Maumere, and Ende. There are regular flights to Maumere from Bali. The drive from Maumere to Moni, the town at the base of Keli Mutu, takes about 3 hours.

COSTA RICA VULCANO POAS
The Poás Volcano is an active stratovolcano in central Costa Rica. Poás has erupted 39 times since 1828.There are two crater lakes near its summit. The northern lake is known as the Laguna Caliente. It is one of the world's most acidic lakes, with a pH of almost 0, and as a consequence supports little or no aquatic life. Lake Botos, the southern lake, fills an inactive crater, which last erupted 7500BC. It is cold and clear, and is surrounded by a cloud forest located within the Poás Volcano National Park. Satellite imageIt was near the epicenter of a 6.1-magnitude earthquake in January 2009 that killed at least forty people and affected Fraijanes, Vara Blanca, the capital San José and the Central Valley region of Costa Rica. It also has had eruptive activity in 2009 involving minor phreatic eruptions and landslides within the northern active crater. Poás eruptions often include geyser-like ejections of crater-lake water.

Water content
The term phreatic is used in Earth sciences to refer to matters relating to ground water below the water table (the word originates from the Greek phrear, phreat- meaning "well" or "spring"). The term 'phreatic surface' indicates the location where the pore water pressure is under atmospheric conditions (i.e. the pressure head is zero). This surface normally coincides with the water table.
In speleogenesis, 'phreatic action' forms cave passages by dissolving the limestone in all directions , as opposed to 'vadose action' whereby a stream running in a cave passage erodes a trench in the floor. Phreatic action usually takes place when the passage is below the water table (although it may happen if the passage is full of water and not saturated with calcium carbonate or calcium magnesium carbonate). A cave passage formed in this way is characteristically circular or oval in cross-section as limestone is dissolved on all surfaces.
Many cave passages are formed by a combination of phreatic followed by vadose action. Such passages form a keyhole cross section: a round shaped section at the top and a rectangular trench at the bottom.
