Experts downplay volcanic threat, warn of more quakes

April 2014 NICARAGUANicaraguan authorities say “there’s no scientific evidence” of a pending eruption of Momotombo and Apoyeque volcanos despite recent earthquake activity along nearby fault lines. In a report released this afternoon by Nicaragua’s Disaster Response Agency (SINAPRED), a team of national and foreign experts say the current seismic activity “could lead to future scenarios of volcanic activity” north of Managua, but there’s no evidence of an immediate eruption. Scientists say there’s no variation to the water quality in the volcanic craters and nearby wells, no emission of sulfur dioxide, and no change to the structure of volcanoes — all good signs. However, the report says, the dramatic increase in seismic activity over the past week is similar to the “hundreds of earthquakes” that proceeded the 1999 eruption of Cerro Negro Volcano in León. The SINAPRED report says the seismic activity between Momotombo and Apoyeque appears to be diminishing, but authorities are not ruling out the possibility of additional aftershocks with magnitudes between 5 and 6 on the Richter Scale. Scientists said the current earthquake activity has centered along a 20-KM fault line north of Managua, between Nagarote and Mateare, which suffered the brunt of the damage from the 6.2-magnitude quake on April 10.
The active fault lines are separate from the fault lines crisscrossing beneath Managua, but continued seismic activity in Lake Managua “could activate some of the faults (in Managua) and produce damage in the city,” the report warns. Scientists also notes the recent “deformation” to the coastline of Lake Managua, which caused the water to recede in the lake. They say they’re investigating the matter, but think it’s “secondary to the high amount of seismic activity in the region.” The report says the overall water temperatures in the lake are considered normal, and said earlier claims of rising temperatures could be due to natural hot springs found in different parts of the lake. The report recommends that Nicaragua remain on high alert and is calling on the Nicaraguan Institute of Territorial Studies (INETER) to “significantly increase their investigations to generate better knowledge of our seismic risks.” –Nicaragua Dispatch

    Fault lines that are associated with a volcano of this type tend to be circular.. around a volcano rather than linear. There are also other indications to signal volcanic activity as being imminent. I think the precautions taken are appropriate. But, always be on the alert to modification of alert status and remember that there is a volcano in the vicinity.

    I hoping that they’re monitoring the volcanic activity in the area. Not good if they would have an unexpected volcanic eruption.

    I live about 20 miles south of Managua. In general, people live day to day and do not prepare or plan for disruptions in daily life. This creates widespread panic and pandemonium at the slightest “disturbance.” Opportunistic crimes flourish and people seem to lose the ability to think rationally. On the other end of the spectrum, however, they are far more accustomed to living without “creature comforts”. Maybe we can all learn from each other and help each other through whatever may come.
