Because of the approaching lava, about 300 more people had to evacuate their houses.
The authorities ordered this.
This increased the number of people who had to get to safety from the consequences of the volcanic eruption to more than 7,000, as the state TV broadcaster RTVE reported on Thursday.
At the same time, around 100 more light to medium earthquakes were registered.
One had a strength of 4.5 and was thus the most violent since the eruption of the volcano on September 19.
Since the northern flank of the volcanic cone collapsed last Saturday, the flow of lava through inhabited areas towards the sea has increased.
The emerging lava was also around 1200 degrees hotter than before and therefore thinner and a little faster.
The analysis of the data from the European Earth observation system Copernicus has so far destroyed 1548 buildings by the lava and covered an area of 680 hectares with lava and ash.
That corresponds to about 950 soccer fields.
Nobody has been harmed so far.
According to the operator Aena, the island's airport was still operational, but was only served by a few airlines such as Binter.
Air traffic to the other major tourist islands in the Canary Islands - Tenerife, Fuerteventura, Gran Canaria or Lanzarote - ran normally.
