A precision of the INGV as for the eruptive episode of December 15 in Stromboli: around 14 h local, following the projections of flaps of fluid lava, small lava flows were formed at two mouths located in the depression of the crater; They began to fill it, and around 2.30 pm the lava overflowed on the northern part and sunk on the northern slope of the Sciara del Fuoco.

Between 2010 and 2014, several lava overflows occurred, some confined in the crater terrace, others with pours on the upper parts of the Sciara del Fuoco.
On two occasions, lava flows spread to the lower parts of Sciara in January 2013 and in August 2014, reaching the sea.
All these episodes are short-lived.

In the Philippines, more than 700 resident families at the foot of Mayon Volcano were pre-emptively evacuated on December 16, due to heavy rains generated by Tropical Storm Urduja.
These rains, likely to remobilize ashes and rocks on these steep slopes, are feared by the inhabitants, who fear to remain trapped in their homes following lahars or landslides.
