Exempel på hur man kan använda ERUPTIVE i en mening

• There has been new eruptive activity since the late 20th century, with a large collapse causing a deadly tsunami in December 2018.
• Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena.
• A volcanologist is a geologist who studies the eruptive activity and formation of volcanoes and their current and historic eruptions.
• Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra (such as ash or pumice), rock and lava samples.
• Volcanic activity at Nevado del Ruiz began about two million years ago, during the Early Pleistocene or Late Pliocene, with three major eruptive periods.
• Butte Lake is the sole remaining fragment of a much larger body of water filled with lava during Cinder Cone's eruptive period.
• Kīlauea is the second-youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain.
• These observations serve to characterize eruptive behavior, identify the nature of precursory activity leading to eruption, define the processes by which different types of deposits are emplaced, and specify the hazards that could be unleashed by each kind of eruption.
• Because eruptive activity ceased 250,000 years ago, glaciers have heavily eroded the volcano's structure, creating precipitous slopes and a horn-like peak.
• On 23 January 2011, the Indonesian Centre for Volcanology and Geological Hazard Mitigation (CVGHM; Pusat Vulkanologi dan Mitigasi Bencana Geologi) reported that since 19 December 2010 volcanic ash and incandescent material had been thrown up by eruptive activity resulting in a heavy rain of material that fell around the crater.
• Since both volcanoes generate magma of dacitic origin, the viscous magma builds up since it cannot flow through the eruptive vent.
• Belknap is not forested and most of its lava flows are not vegetated, though there is some wildlife in the area around the volcano, as well as a number of tree molds formed by its eruptive activity.
• Located on the tripoint of Zambales, Tarlac and Pampanga provinces, most people were unaware of its eruptive history before the pre-eruption volcanic activity in early 1991.
• These eruptive events created many of Oahu's well-known landmarks, including Punchbowl Crater, Hanauma Bay, Koko Head, and Mānana Island.
• Most eruptive activity appears to be lava flows, though some small pyroclastic flow deposits have been noted in drainages radiating from the mountain.
• Fissure vents in Iceland tend to produce calmer effusive eruptions, but can be associated with large volumes of lava (flood basalt events) and some have had prolonged eruptions with numerous eruptive episodes, lasting for years.
• This promontory of "high" beaches is the extreme western immersion of the ancient eruptive Sintra massif, as evident from the rose-coloured granite in the north and syenite of the Ribeira do Louriçal in the south.
• Cumbre Vieja - In the 2021 La Palma eruption, new eruptive vents tended to announce themselves with a phreatic explosion, followed soon after by the opening of a new fissure vent in the same location.
• Radiometric dating ranged mostly from 450,000 to 320,000 years ago, although several pieces strayed lower; this indicated a period of eruptive history at the time.
• That the water entrapped within the edifice did not vapourise is shown by the absence of phreatomagmatic explosions except the mildly explosive eruptive activity that occurred at the Hoyo Negro vent from 12 to 22 July: steam escaping explosively from the ground is often a precursor of volcanic activity.
