The scientists who have followed from the first day the birth of a new Volcano in Old Summit, in La Palma, do not tire of repeating that it is a "manual" stonbolian eruption, which fulfills everything that could be expected from a Phenomenon of these characteristics in the Canary Islands.
However, by "normal" that is in geological terms, the figures of this volcano are shocking: a volume of volcanic materials expelled only in a month that they had filled twice all the reservoirs of Gran Canaria, thousands of small earthquakes with which they The subsoil of La Palma has not let alone a single day, 1% of the island covered in Malpaís, 8% of its evacuated population of their homes, a delta of lava won to the sea of an area close to the Vatican State ... and, above all, thousands of victims and homes and farm farms destroyed.
These are some of the most striking data and magnitudes that leaves this volcano still unnamed after a month of eruption.
It is the great success of all the deployment of scientific and emergency teams that works in La Palma for more than a month: a single life has not been lost, nor has anyone been injured.
Maximum magnitude of the earthquakes registered to date, at an earthquake on Saturday, October 16 that also marked the maximum intensity measured on the island in these weeks: IV-V on a maximum of XII, between "widely felt" and "strong" . No damage.
Those that have occurred in the palm since there are historical records in the Canary Islands; That is, from the conquest of the island by the Kingdom of Castile in the s. XV: Tacande / Burned Mountain (1430/1440), Tehuya (1585), Martín or Tigalate (1646), San Antonio (1677/1678), the Charco (1712), San Juan (1949), Teneguía (1971) and the current.
Average depth of earthquakes registered in the last week. The maximum depth from the beginning of the eruption exceeds 36 kilometers; The minimum, does not reach 1,000 meters.
Height that have reached some fronts of lava as it passes by several places of the plains of Aridane, like the town of allow. But it is not the maximum: thicknesses of 50 meters have been detected in the laundry when it was exceeded some vagues from the terrain.
It is what measures the youngest field in Spain. The "fajana" or delta that laundas lava wash has formed when entering the Atlantic Ocean by the Beach of Los Guirres, in Tazacorte.
Accumulated length of the road sections on which lava castings have passed.
Time elapsed from the previous eruption that occurred in La Palma, in 1971, at the southern end of the island, in Fuencaliente. The volcano that formed received the name of Teneguía.
Measurement of the perimeter around the lava zone.
Average duration of eruptions in La Palma, which have had a constant descending trend to date, from 84 days of the volcano Tehuya (1585) until 24 of Teneguía (1971). This volcano has already broken that dynamic.
Surface of crops damaged by the volcano: 106.91 of Plataneras, 51.51 of vineyards and 16.31 of avocado.
Number of land buried by lava in El Paso, the plains of Aridane and Tazacorte, according to the Copernicus satellite. It represents 1% of the area of the island (7.43 over 708 km2).
Affected by the castings since the eruption began, 854 of residential use, according to the cadastre figures. The European Satellite Emergency Monitoring System COPERNICUS elevates that double count: 1,826 properties of all types destroyed.
Approximate figure, fluctuates almost every day. Are the national police, local agents, civil guards, firefighters of various islands, forest brigadists, soldiers of the UME and the land army, navy sailors and civil protection members or red cross, among other bodies, mobilized to protect The population of La Palma versus any risk.
Temperature reached by some of the castings that have traversed the Aridane Valley.
Neighbors who resided in the homes affected by the volcano: 905 in the plains of Aridane, 290 in step and 112 in Tazacorte.
Maximum width that the laundry has reached by expanding through the Aridane Valley.
Since this volcanic crisis began as a seismic crisis, with maximum magnitude of 4.6 on October 16.
Educational community affected by the suspension of classes in the municipalities of El Paso, Los Llanos de Aridane and Tazacorte.
Evacuated from their homes in El Paso, the plains of Aridane and Tazacorte for being in the area buried by the castings or within the perimeter of risk by gases or fall of pyroclastic materials. Or what is the same, one in five people who resided in those municipalities (about 7,000 on 32,984 registered that add up the three town halls) has had to leave the house of it. Of these, 321 are staying at a Fuencaliente hotel.
Height that reached the ash plume issued by the main cone of the volcano on September 28.
Volume of gases that ejects the volcano every day, mostly sulfur dioxide (SO2). It would be necessary that this amount descended to 100 tons per day so that scientists consider it an indication that eruption is coming to an end.
Number of bananas that exported the palm every year. It is the economic sector and the cultivation most affected by the eruption.
Donations from individuals in favor of the victims performed through the Cabildo of La Palma.
Number of materials issued by the volcano according to the high strip of the last estimate disseminated by the Scientific Committee (75 million M3, with a rise up or down of 25 million). It is more that they expelled it together the volcanoes of San Juan, in 1949, and Teneguía, in 1971. By volume, this is already the third most important eruption in the history of the Canary Islands, after that of Timanfaya, in Lazarote (1,000 million m3 ), and the Tagoro submarine volcano, in iron (329 million).
