Title: 1669 eruption of Mount Etna
Content:  During the night of 24 March, a violent earthquake took place and was followed by activity on the main summit of Etna. The next day at 10:00 an explosive eruption occurred at the summit, and an "immensely high" eruption column rose over the volcano. No caldera collapse took place on the volcano but landslides affected the summit crater. There is disagreement between contemporaneous records that mention a collapse of the summit in 1669, those which do not, and 21st-century research that indicates there were no major changes in the morphology of the summit during the 1669 eruption.
Title: Mayon
Content:  On August 10, 2008, a small summit explosion ejected ash 200 m above the summit, which drifted east-northeast. In the weeks prior to the eruption, a visible glow increased within the crater and increased seismicity.
Title: Masaya Volcano
Content:  satellite data. A hot spot appeared on satellite imagery, and there was a possible explosion. On April 23, 2001, the crater exploded and formed a new vent in the bottom of the crater. The explosion sent rocks with diameters up to 60 cm which travelled up to 500 m from the crater. Vehicles in the visitors area were damaged and one person was injured. On October 4, 2003, an eruption cloud was reported at Masaya. The plume rose to a height of ~4.6 km. In 2008, the mountain erupted spewing ash and steam. This volcano is monitored by the Deep Earth Carbon Degassing Project. Volcanic gas emissions from this volcano are measured by a Multi-Component Gas Analyzer System, which detects pre-eruptive degassing of rising magmas, improving prediction of volcanic activity. On March 4, 2020, tightrope daredevil, Nik Wallenda, walked on a steel cable over the caldera.
Title: Mount Matavanu
Content:  The eruption began on 4 August 1905, with a new crater being formed nine miles to the east of Mata o le Afi, which had erupted in 1902. An expedition led by governor Wilhelm Solf observed flames shooting 400 feet into the sky at intervals of ten seconds along with lava flowing through the bush. An expedition to examine the crater found "a larger heap of stones about 300ft high, from the top of which, at intervals of about 10 seconds, masses of stone were being thrown up into the air". A lava-flow 100 feet high had flowed 2.5 miles towards the sea. The early phase of the eruption was mostly explosive, but in September large amounts of

Content:  manufactured by ETA, contained between 1.5 and 2 kilograms of ammonal and chloratite, and a timer. Txapote was surveillance the area while Amaya was setting up the bomb. The two ETA's members returned by train, being picked up in the halt of Añorga and transferred to Andoain's town by Gregorio Escudero. On January 9, 1998, at 7:40 a.m. José Ignacio Iruretagoyena took his car and head to his job. After driving for a few meters, the artifact exploded around 7:50 a.m. at Urdaneta's street. As soon as the explosion was produced several passers-by found José Ignacio, who had lost several limbs of the body. 
Title: Mount Asama
Content:  An explosive eruption occurred on 8 April. Incandescent tephra was ejected, and ash fell 250 km from the volcano.
Title: Yubileynaya mine
Content:  On May 24, 2007, a methane explosion at the mine killed 38 miners and injured a further 7, one of whom subsequently died. Investigators believe that the explosion was caused by a spark from a damaged cable.
Title: 1902 eruption of Mount Pelée
Content:  explosions resumed the night of 5 May. The following morning, parts of the eruption plume became incandescent, signifying that the character of the eruption had changed. The phreatic explosions had finally given way to magmatic explosions as magma reached the surface. The explosions continued through the next day and night. A brief lull was shattered by a tremendous explosion at about 8:00 a.m. on 8 May. A ground-hugging cloud of incandescent lava particles suspended by searing turbulent gases moved at hurricane speed down the southwest flank of the volcano, reaching Saint-Pierre at 8:02 a.m. Escape from the city was 
Title: Soputan
Content:  column 5,000 metres into the air. On 6 January 2015, an eruption began when an explosion caused a partial collapse of a summit lava dome, sending an avalanche down the west flank. On 4 January 2016, the volcano exploded sending an ash plume to 2000m, which prompted authorities to establish a 4 km exclusion zone around the volcano. In 2018, Soputan erupted on 3 October, and again twice on 16 December. All three times the volcano spewed a massive column of ash more than 6,000 m (19,700 ft) into the sky. The October eruption occurred about a week after a powerful earthquake and tsunami struck the island.
Title: Irganai Dam
Content:  On 7 September 2010, fire broke out at power station's hall. On 9 September 2010, Russian security forces defused an explosive device equivalent to 3 kg of trinitrotoluene in the room. On 31 January 2011, a stick of dynamite was discovered at the power station.
