The scientists caused Thorsday in the Chans of an eruption of the Mount Spurr volcano in Alaska, a situation closely monitored by the officials of Anchorage, the largest city in the state.
According to a statement from the Alaska Volcano Observatory, the hood of an eruption has decreased slightly since March because the volcano has exhibited less signs of disturbances. However, the mountain remains at a yellow alert level because the disturbances that occur are greater than normal, not of non -upstream.
The AVO said that bad climatic conditions have prevented another flight over the volcano to monitor any volcanic gas that can be ventilating from the mountain since the last on March 21, almost a month ago. The satellites have not detected any sulfur dioxide from the volcano since April 3, the AVO said, but that may be due to the clouds that have maintained the wrapped mount.
The scientists said that despite the lowest activity, the volcano continues to exhibit signs of earthquake disturbances.
Avo said that riots could continue to decrease or resume again, increasing the possibilities of an eruption. Until the climatic conditions improve and new gas data can be collected, a real determination cannot be made.
The scientists said they cannot give a time frame for an eruption if one occurs, but they hope to see changes in the data before one happens, as the magma approaches the surface.
Mount Spurr has not exploded since 1992.
Authorities in Anchorage said they are closely monitoring Mount Spurr and are preparing for Ashfall if an eruption occurred. The biggest problems will be a drastic reduction in air quality and machinery that are obstructed with ashes, authorities said.
