A recent estimate of the total annual cost of landslide damage is in excess of $1 billion {Schuster, 1978}. The average cost for earthquake insurance is between $100 and $300 per year. Armero Tragedy. The areas worst affected were Manila . More recently, the U.S. Geological Survey estimated annual losses to be between $2 billion and $4 billion per year. [3] The magnitude was recalculated as 7.5 on the moment magnitude scale in the ISC-GEM catalogue published in 2013. Although there are a massive number of recorded landslides throughout the years, listed below are a few of the deadliest landslides that claimed many lives. In the Yasman River valley, which lies almost entirely within the area of greatest felt intensity, a large number of such flowslides coalesced in tributary valleys before combining into one massive flowslide that travelled the length of the valley. On November 13, 1985, the Armero tragedy struck upon the eruption of the Nevado del Ruiz stratovolcano in Tolima, Colombia. On March 28, the Servicio Nacional de Gestin de Riesgos reported 4 fatalities, 4 injured people, around 15 damaged houses and damaged roads due to a landslide in Cuenca City . The death toll from a mudslide that hit the north-western US state of Washington has risen to 29 people, with 20 others still missing. First, they look at the Khait landslide (termed in the paper as a rockslide / loess flow), which is still clearly visible in the landscape, even on the low resolution Google Earth imagery available for this area: For the Khait landslide they conclude that the volume was probably rather lower than earlier estimates have suggested. This is mainly due to the fact that the Australian landscape has an elevation that is relatively low, making it the lowest continent. What has been the 10 worst landslide disasters in history?
