The 1815 eruption of Mount Tambora in Indonesia resulted in a massive dust cloud that caused the "Year Without a Summer" in 1816. The eruption spewed a huge amount of ash and sulfur dioxide into the atmosphere, leading to widespread cooling and crop failures across the Northern Hemisphere.
The most destructive eruption of Sakurajima occurred in 1914 when a large explosive eruption caused significant damage to surrounding areas and resulted in the formation of the current volcanic island.
The last known eruption of Pilot Knob in Missouri occurred about 1.48 billion years ago during the Proterozoic Era. The volcanic activity at Pilot Knob resulted in the formation of iron-rich volcanic rocks that are now known as the Iron Mountain Formation.
The last known volcanic eruption in Australia occurred at Mount Gambier in South Australia around 5000 years ago. It resulted in the formation of several volcanic cones and the creation of the Blue Lake, a popular tourist attraction today.
The largest eruption in the US in the last 10,000 years was the eruption of Mount Mazama, which resulted in the formation of Crater Lake in Oregon. This eruption occurred around 7,700 years ago and was a massive volcanic event that deposited ash over a wide area.
The last eruption of Mount Mayon was in January 2018. It was a phreatic eruption that resulted in ash plumes and volcanic lightning.
The most recent eruption of Kilauea began on December 20, 2020 and lasted until May 2021. This eruption resulted in lava flows, volcanic gas emissions, and other volcanic activity in the area.
The shockwaves from the Krakatoa volcanic eruption in 1883 traveled around the Earth seven times. The eruption was one of the most powerful volcanic events in recorded history.
Earthquakes occur at that moment
The planet Earth has always had volcanic eruptions, since its earliest formation about four and a half billion years ago.
The ash cloud from the island's eruption traveled eastward, affecting nearby areas with ashfall and volcanic gases.
Around 60 million cubic meters of volcanic material were expelled during Mayon volcano's 2018 eruption. This eruption resulted in ashfall, pyroclastic flows, and lahars.
