The Gran Canarian palms
Four days to put an end to the La Palma volcano and, one more day, the signs of exhaustion of the eruptive process. Scientists peer into the dormant volcanic cones for a gas measurement that is’punctual and sporadic“And have observed liquid sulfur dioxide, which Involcán has defined as” drops of blood. “
Drops of liquid sulfur, like blood drops of the arteries of the volcano, some areas of the interior of the crater stain red “, the scientists have explained.
The deformation of the terrain recorded at Jedey station LP03 is in reversion after reaching its maximum of eight centimeters.
The tremor signal that measures the noise of the magma under the crust is at «background noise” and seismicity at “very low” levels with magnitudes that do not exceed 3 points.
The emission rate of sulfur dioxide derived from the volcanic process has a low value that does not point to a magma rise but rather to the solidification of the remnant of the volcanic tubes, as pointed out by Carmen López, spokesperson for the scientific committee of the Canary Islands Volcanic Emergency Plan (Pevolca).
Seismicity continues to decline in #LaPalma
The volcanic tremor disappeared for a week.
The seismic noise that we now see in TBT is related to meteorology (possibly the rain in the Barranco de las Angustias)

The spokesman for the Pevolca steering committee, Rubén Fernández, has indicated that “once the process is finished, if with luck and everything goes well, on the 25th»,« A situation of risk for the population will remain for many weeks ».
Thats why he return home of evacuees it will be produced “as far as possible” as long as there is security to do so. At this time, the prohibition to enter tool rooms and other types of buildings has been activated for farmers who have accessed the evacuated areas in the southern area of the emergency, with the exception of La Bombilla.
The biggest concern at the moment it is the concentration of harmful gases in the areas of Puerto Naos, El Remo and La Bombilla, he said.
The air quality in relation to the concentration of sulfur dioxide has been good except in the San Antonio station where it reached the level of regular, and regarding the concentration of particles below 10 microns, the levels have ranged between good and reasonably good.
