Masaya volcano has increased to almost double its magma movement and its seismicity, said today the Nicaraguan Institute of Territorial Studies (INET). The signals of the amplitude level of the tremor in real time (MRS, for its acronym in English), measured every ten minutes, which under normal conditions varies between 150 and 620 units on the Masaya, exceeded the value today 1000, said the INETER in its statistical report after twelve hours of surveillance. The MRS real-time measurements indicate the total activity of a volcano, the movement of magma, rock falls and even earthquakes, and is one of the tools volcanologists to evaluate a possible eruption.
The volcano has caused alarm among the population of Pacifico Nicaragua , Tuesday , when it generated a series of earthquakes of magnitude M 4.1 on the Richter scale, without damage or significant losses have been reported.
Masaya, known among scientists as the most active volcano in Latin America has increased its activity in December, when a “lava lake” appeared in the crater Santiago. Its level has increased in recent days, according to official information. The Centre for Disaster Operations (CODE) of Nicaragua was activated yesterday after the earthquake. The classes were suspended for a day in three towns around the volcano. In recent days, authorities of the Volcano National Park of Masaya have closed their doors to the public, attracted by the place that can be reached by car to the edge of the main crater, Santiago. The National Disaster Prevention System (SINAPRED) has not ruled out a major activity of Masaya at any time, and made recommendations on how to deal with a possible earthquake originating from the volcano.
News from Ineter 09/02/2016. :
In the last 24 hours, with low emissions of volcanic gases were recorded the occurrence of two earthquakes related to the movement of magma in the caldera of Masaya volcano.
The first took place at 6:43 p.m. yesterday in the north of the caldera of Masaya, and had a magnitude of M3,2 degrees and was felt by the population.
The second earthquake took place at 22:17 yesterday, near the crater Santiago, of magnitude M1,2 degrees.
The volcanic tremor of high energy persists and seismic amplitude in real time (MRS) has averaged at high values between 100 and 780 units.
