The largest volcanic landslides on Earth occur from submarine volcanoes and are several times larger than those that occur on land. Submarine landslides with volumes of 100–150 km 3 (24–36 cu mi) have occurred in the Canary Islands within the last 43 million years, but the largest submarine landslides could have been up to 900 km 3 (220 cu ...
A landslide in which the sliding surface is located within the soil mantle or weathered bedrock (typically to a depth from few decimeters to some meters) is called a shallow landslide. Debris slides and debris flows are usually shallow. Shallow landslides can often happen in areas that have slopes with high permeable soils on top of low ...
The 2010 Mount Meager landslide was a large catastrophic debris avalanche that occurred in southwestern British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7).More than 45,000,000 m 3 (1.6 × 10 9 cu ft) of debris slid down Mount Meager, temporarily blocking Meager Creek and destroying local bridges, roads and equipment.
At 8:32 am, a magnitude-5.1 earthquake centered directly below the north slope triggered that part of the volcano to slide, [32] approximately 7–20 seconds after the shock, [9] followed a few seconds later by the main volcanic blast. The landslide, the largest subaerial landslide in recorded history, traveled at 110 to 155 mph (177 to 249 km ...
Date Place Name/article Position Volume Comments Sources 1.4 Ma off northern Molokai, Hawaii: Wailau Slide 2,500 km 3: The northern third of East Molokai Volcano collapsed suddenly into the Pacific Ocean in a 25-mile (40 km) wide landslide with a 120-mile (193 km) run-out that climbed uphill 900 feet (274 m) from the Hawaiian Trough over the last 80 miles (130 km).
Essentially, there are two main types of volcanic landslide: lahars and debris avalanches, the largest of which are sometimes termed sector collapses. An example of a lahar was seen at Mount St Helens during its catastrophic eruption on May 18, 1980. Failures on volcanic flanks themselves are also common.
It triggered a landslide on the slopes of the Mauna Loa volcano, five miles (8.0 km) north of Pāhala, killing 31 people. A tsunami claimed 46 additional lives. A tsunami claimed 46 additional lives. The villages of Punaluʻu , Nīnole , Kāwāʻa, Honuʻapo, and Keauhou Landing were severely damaged.
