New evacuations, on the night of the 13^th and then on the morning of the 14^th, have been ordered in La Laguna given the advance of the active lava flows to the north of the flow field. These have affected about 400 extra people, increasing the total number of evacuees from the eruption to around 6,400. The two branches of the northern-most lava flow are still active, with the wider southerly branch slowing down, but the more northern branch continues to advance towards La Laguna. Large blocks are observed being transported in the northern lava flow, which are remnants of small collapses of the cone. The eruption continues to show a strombolian mechanism with both explosive and effusive phases, producing pyroclastic deposits and lava flows.

Volcanic tremor remains at an elevated level of amplitude, with pulses of higher intensity also being seen. Earthquake activity was also more intense and a greater proportion of deeper (20-40 km) earthquakes than seen in previous days. 110 events were recorded, peaking at 4.5 mbLg. Regarding deformation, an inflation of 5 cm has been seen at the LP03 station between Jedey and Las Manchas, which is the closest station to the eruption site. The ash and gas plume reached 2600 m, and the SO2 emissions from the volcano remain similar to previous days, at 14,542 tons per day, although this is an underestimate. Both PM10 and SO2 concentrations remained below threshold levels throughout the day, although with respect to SO2 the stations in Los Llanos, El Paso and Tazacorte came close to exceeding the hourly threshold (350 μg/m³) between 6-11 am local time.
