La Palma eruption – 7th January 2022
After the successful return of more evacuees to their homes and reduction in size of the exclusion zone, the focus turns to the restorative work needed to repair damage to basic and essential services. Heavy machinery has been digging on the cooled lava flows surrounding La Laguna mountain, and work on an access road to Puerto Naos has been going well, despite being affected at times by gas levels in the area. Elsewhere, a jetty is being built near Punta del Negro to improve access by sea, although bathymetric studies are needed to assess the changes to the seabed caused by the lava flows before this can be completed. Finally, in the coming weeks the government are hoping to restore the drinking water network to the area to the south of the flows. PEVOLCA have also indicated further returns of evacuated people soon may be a possibility.
For the first time since the eruption began, no earthquakes were recorded throughout the day by the island’s seismic network, and volcanic tremor remains at background levels. No significant changes have been recorded across the deformation network either. SO2 emissions from the main cone remain at a low level and are a product of the escape of gases from residual cooling magma. Regarding air quality, SO2 concentrations remain good across all stations, and concentrations of PM10 particles remained between good and reasonably good across all stations. However, changes in winds over the next few days may introduce Saharan dust into the atmosphere, which could impact PM10 concentrations.
