Presently, there are no detectable signs of the beginning of a volcanic eruption at Grímsvötn.
The decline in hydrological in rivers, streams and water resources in the vicinity of the volcano Hekla is greater than that explained solely by the drought and lack of snow in the mountains.This is the estimate of Hjartardóttur Driva , former senator, who lives in the Springs Rangárvellir. "This is unusually high considering that it is due to precipitation solvent *," says Drífa and says that the decrease was about thirty centimeters in the Springs Physicians at her home. "And this has happened to an eruption, some weeks and months earlier, the water has hripað like down. " This development follows a hurry to have taken place in all fall and has increasingly narrowed the doctors. "I have lived long in the Springs and never seen such a small brook before." Sverrir Haraldsson, farmer in Under Rangárvellir, in the vicinity of Hekla, believes, however, profit on them due to less flow in the Hekla volcanic activity. "You feel time nothing mysterious in a few snow-free winters and little rainfall at all," he says and says water does not have gone very quickly. "But it has increased when a lot this year." As soon Sverrir said it right check that there are signs leading up to the eruption of Hekla to reduce the amount of water in the vicinity of the mountain. "But it just has not been normal in frequent craft," he added. In the area of people wonder, however, admitted that whether the changed water status may be an indication that an eruption is coming. Hjörleifur Sveinbjörnsson, a geologist at the Icelandic Meteorological Office, said no seismicity has been recently in the vicinity of the mountain. "There are no earthquakes and no see the expansion suggest," he says, but thinks can not be excluded that the low water position in the vicinity of the mountain is available for a longer run-up than are earthquakes. „Hekla er náttúrlega löngu komin í stöðu og þannig séð tilbúin. "She 's a natural long been ready for a eruption . " But indicators have never shown any particular lot sooner than this to two hours before an eruption, "he says, and recalls that this was it just be the last Hekla eruption." Then came the first smáskjálftar about two hours earlier and could not see a change in expansion meters At the same time emphasizes Hjörleifur to unusually low precipitation has been widely and has fallen in rivers and lakes. Fast drying may be an indication of imminent eruption, but the trend in recent weeks and months is rather due to lack of rainfall.
Scientists now closely monitor seismic episodes and land uplift with Krýsuvík and civil informed of developments. pressure increase in Earth's crust which is considered below can be caused either by the dynamic influx or changes in geothermal systems. Earthquake tremors with 40 quakes became Krýsuvík tonight but seismic wave was resumed in the area this fall after a quiet period earlier this year. Earth civil informed last year of unusually high landrise in a small area southwest of the lake broke, but then rose to a country where about three centimeters. Land rise was attributable to increased pressure in the Earth's crust in three to four kilometers, according to Freysteinn Sigmundsson geophysicist tion. This increased pressure was ascribed either of magma influx or variations in geothermal systems. Land rose went back last winter and the first half of this year and then began again in spring. Sigrid Hreinsdóttir geophysicist says that it has been decided to patrol the area better and to this end has two new GPS-meters have been set up earlier this year. Seismic wave quests autumn scientists were not surprised and had some time before they let civil knowing the expected shifts in the region. Scientists are not sure what's going on there, but most lean to the land rise can be explained by changes in the geothermal system, possibly associated with magma movement. Is not expected to eruption is coming, but the reason is believed to patrol the area well.
