To counter potential road disruption from the influx of tourists the weekend for All Saints’ Day on the 1^st November, the authorities have launched a shuttle bus service from Breña Baja on the east of the island to the area of the eruption for tourists. People using private vehicles must not use the LP-3 road, to keep it free for emergency services, residents, public transport and military vehicles. The volcano remains in the same behaviour pattern in the last few days with high lava effusion rates from the NW flank of the main cone, which has shown some stability as well over the last couple of days. At noon however, there was a more intense period of ash emissions and audible explosions for several hours, which could be caused by intense degassing according to PEVOLCA. The most active lava flow, to the south of the original flows, has advanced 900 m in the last 24 hours over new ground. At the current rate, it could threaten the road that connects Puerto Naos to towns further south of the lava flows. Earthquakes remain at a high magnitude and frequency at intermediate (10-15 km) depths. 185 events were recorded, peaking at mbLg 3.7.

No significant deformation is now seen in the proximal stations after the reversal of the signal seen at the Jedey station the last couple of days, whilst a slight deflation of deep origin continues to be recorded in distal stations. SO2 emissions remained slightly lower although due to technical issues an exact value could not be determined, whilst the ash and gas plume reached, 3300 m. The tremor remains high, with pulses of intensification. Air quality remained improved relative to previous days. The daily and hourly thresholds were not exceeded in any of the stations with respect to both SO2 and PM10 concentrations, except in Los Llanos, which exceeded the daily threshold (50 μg/m³) for PM10 concentrations.
