La Palma Volcanic Eruption: Over 22,000 Tremors Later and Entire Villages are Being Buried in Lava
According to Geologists and other scientists monitoring the Cumbre Vieja volcanic mountain ranges, an eruption was not imminent despite the tens of thousands of tremors before the eruption.
The La Palma volcanic eruption came as a surprise to many on Sunday the 19th of September mainly due to scientists’ insistence that a volcanic eruption was “not imminent”. However, it was no surprise also as the Spanish Canaries Island of La Palma had experienced over 22,000 tremors before the onset of the volcanic eruption. Just over a week later now, and the island is covered in a blanket of ash with entire villages being swept away and buried in lava.
Where Scientist Got It Wrong
According to Geologists and other scientists monitoring the Cumbre Vieja volcanic mountain ranges, an eruption was not imminent despite the tens of thousands of tremors before the eruption. The volcano had been inactive for over 50 years with no eruption and this might have misled the scientists into thinking that it had gone overtly inactive. La Palma’s last volcanic eruption was in 1971 and lasted for over 21 days. La Palma, one of the smallest Canary Islands in Spain, is known for its fertile volcanic soil which the island’s farmers depend on for their livelihoods. Sunday’s eruption, however, saw farmers rushing to save their crops before the lava, which is molten rock that turns black when exposed to air, reached their farms.
A volcano is in many ways similar to a pressure cooker and when it reaches maximum pressure, the lava is spewed out in a violent rumble of molten rock that is over 1000 degrees Celsius. Some of the lava falls back into the volcano, creating more pressure that is spewed out again, in a cycle of lava and pressure. As this happens, a huge plume of volcanic ash is released into the air that later falls down to the earth as black ash or soot that can reach levels where it can be likened to snow. As it stands, most of the island is covered in this black ash, which is harmful to humans. The authorities in La Palma have, therefore, been advising residents to wear personal protective eyeglasses and masks to avoid inhaling the volcanic ash or the ash entering their eyes.
Heading to Sea
When the lava reaches the sea, it will produce harmful gases that could irritate the lungs, eyes, and skin as they are toxic and acidic. As such, La Palma is bracing for a possible evacuation of the affected residents even as over 6,000 residents and 400 tourists have already been evacuated. Those whose homes were affected were given just an hour to evacuate on the onset of the eruption, many of whom have now lost their homes.
La Palma is not known as a ‘touristy’ island, much unlike the other Spanish Canary Islands. However, the volcanic eruption has attracted tourists who have reveled in the ‘joy’ of watching a volcano erupt. Nonetheless, residents feel that it is unfortunate that tourists are enjoying the demise of their homes and the loss of their livelihoods. The eruption is set to last for anywhere between twenty-four and eighty-four days.
What has been Lost so Far
Over 593 acres of land spanning 15.7km have been affected by the lava flow. Fourteen kilometers of roads have already been destroyed, with over 390 buildings either fully destroyed or damaged. The cloud of ash resulting from the eruption has gone as high as 4.5 km, leading to the grounding of flights to and from the island. According to the Spanish Prime Minister, Pedro Sanchez, there could be “very long days ahead”. The Prime Minister was slated to attend the UN General Assembly but canceled and instead traveled to La Palma to assess the situation.
