Jun 28, 2018 · Plumes of volcanic material traveled by air and by sea as the small Pacific island erupted in June 2024. A volcanic fissure on the Reykjanes peninsula came alive again with voluminous, vigorous flows. The latest fissure eruption on Iceland’s Reykjanes peninsula was the largest of four recent bouts of activity near the town of Grindavík.
May 20, 2018 · Mt. Shasta is an active volcano that has erupted at least once per 800 years for the past 10,000 years, with an increased eruption frequency of about once per 250 years over the past 750 years. The region around Mt. Shasta is susceptible to lava and pyroclastic flows, lahars (mudflows), avalanches, and earthquakes.
In October 2001, a sleeping volcano in the remote South Sandwich Islands began spewing ash and lava from its summit. It was Mount Belinda’s first eruption in recorded history. Less than 24 hours after the eruption began, a research team based nearly 9,000 miles away at the University of Hawaii was already estimating how much energy was ...
Dec 20, 2021 · According to a mid-December update from the Copernicus Emergency Management Service, the eruption has destroyed at least 1,600 buildings. Lava has consumed at least 12 square kilometers (5 square miles) of land, including at least 4 square kilometers of crops. Initial estimates say that the eruption has caused at least 550 to 700 million euros ...
Snow-capped Colima Volcano, the most active volcano in Mexico, rises abruptly from the surrounding landscape in the state of Jalisco. Colima is actually a melding of two volcanoes, the older Nevado de Colima to the north and the younger, historically active Volcan de Colima to the south. Legend has it that gods sit atop the volcano on thrones ...
Ruapehu is one of New Zealand’s most active volcanoes, with ten eruptions since 1861. The eruptions aren’t the only threat from the volcano, however. Among the most serious threats is a volcanic mudflow called a lahar. In between eruptions, a lake forms in the volcano’s caldera from melting snow. If a previous eruption has deposited a dam ...
After two months of eruptions with activity ranging from lava flows, to outburst floods, to ash plumes—Iceland’s Eyjafjallajökull Volcano appeared to be quieting down. As of May 24, 2010, heat signatures at the summit had dropped according to the Iceland Met Office, and explosive eruptions of ash had not occurred for several days.
Sensing Remote Volcanoes. MODIS acquired an image of Nyiragongo Volcano in the Democratic Republic of Congo, Africa (location shown top left, satellite image shown middle left) on January 17, 2002, less than one hour after the eruption began. The red box in the middle left image (which indicates the area enlarged at bottom left) shows an ...
Jan 18, 2022 · The volcanic island first rose from the sea in January 2015. Eruptive activity built up ash around a new volcanic cone and connected the older, more lava-based islands of Hunga Tonga and Hunga Ha‘apai to create Hunga Tonga-Hunga Ha‘apai. Signs of the island’s recent demise were easy for satellites to spot in the seas.
Stromboli is a stratovolcano composed of alternating layers of hardened ash, lava, and volcanic rocks. Strong eruptions have been recorded at the volcano for more than 1,000 years. In 2002, a major eruption caused a small tsunami and damaged Stromboli Village on the north side of the island. Eruptions at Stromboli are not unusual.
