Holmfirth floods

Holmfirth FloodBilberry reservoirfailure of the Holmfirth reservoir
The Holmfirth floods refers to a number of instances when severe flooding had occurred in the Holme Valley, West Yorkshire, England affecting Holmfirth and other settlements in the valley. The earliest record dates from 1738 and the latest from 1944. The most severe flood occurred early on the morning of 5 February 1852, when the embankment of the Bilberry reservoir collapsed causing the deaths of 81 people. It is recorded as the 23rd most serious, worldwide, in terms of loss of life from floods and landslides in human history. Rainstorms caused the River Holme to burst its banks and flood the valley. Though there was damage to farmland there was no loss of life.

In Italy, December 30 saw hundreds of homes in Tuscany evacuated because of flooding and Spain's rescue services were on yellow danger alert after flash floods destroyed roads and landslides swept railways away. Transport Links between Almeria, Granada, Málaga and Sevilla were severed. Drought-blighted Andalusia has had its fifth day of rain, and Portugal was on orange flood alert. Authorities said the rain had destroyed millions of Euros worth of agricultural produce. The harbours were closed and the Madeira archipelago islands were also under threat of both flooding and gale-force winds, as 110 km/h whipped up six-metre -high waves.

2016 Pakistan flood

After heavy rains and flash floods in Pakistan, at least 71 people were killed and another 34 hospitalized. Rain started at night of Saturday, April 3, rainfall began to spur floods in the Khyber Pakhtunkhwa region in the northwest. Heavy rainfall is common in Southern Asia during the pre-monsoon season. In response to floods, Khyber Pakhtunkhwa government began to administer relief for those affected. Rural areas with poor infrastructure were highly susceptible, and, consequently, some 150 homes were destroyed in the event. The floods also caused deadly landslides that killed another 23 people. However, 5 survived and were rescued.

"Mass Wasting" – The episode explains the phenomenon of mass wasting — the downslope movement of earth under the influence of gravity. It discusses various factors involved in mass wasting, including the rock's effective strength and pore spaces, and different types of mass wasting such as creep, slump, and landslides, as well as rockslides, debris flows, and mudflows. It explains the influence of slope angle, water and rain, and human activities such as the construction of buildings and roads, on mass wasting.

Hurricane Liza

Liza weakened as it moved northward into the Gulf of California. Shortly thereafter, the hurricane made its second landfall north of Los Mochis, Sinaloa with winds of 115 mph (185 km/h), making it one of 13 storms to make landfall as major hurricanes in the basin. Inland, the hurricane rapidly weakened and dissipated on October 2. Prior to the arrival of Liza, residents along the Gulf of California coastline were evacuated, although some refused to leave their homes. Radio stations warned all nearby ships to remain at harbor. Liza brought heavy rainfall to the area, which caused significant flash flooding.

When Disaster Strikes (TV series)

When Disaster Strikes covers fires, floods, hurricanes, landslides, sewage-filled basements – every situation is different and requires a creative, no-nonsense plan. The only thing common to the disasters are emotionally devastated victims. When Disaster Strikes episodes include: Fire: After a fire blazes through a middleclass man’s home - a remediation team attempts to restore it under the shadow of arson allegations. Mould: The disaster team struggle to overcome a toxic mould plaguing a Cincinnati family home and post Hurricane Katrina New Orleans.

Wildfire emergency management

In the event of a wildfire, floods and landslides can often occur after the burn due to the drastic changes the fire can have caused in the terrain and the condition of the ground. Those who live within the proximity of a wildfire are susceptible to experiencing loss and damage from these events. Floods and landslides can occur long after the fire has ceased its burn; fires leave the ground charred with little to no vegetation, which normally absorbs rainfall. Without the vegetation, the rainwater can cause flash floods for up to five years after a wildfire.


It describes an extreme storm that might impact much of California causing up to $725 billion in losses (most caused by flooding), and affect a quarter of California's homes. The event would be similar to exceptionally intense California storms which occurred between December 1861 and January 1862. The storm would be a 1-in-1000-year event. The name "ARkStorm" means "Atmospheric River (AR) 1,000 (k)." The hypothetical ARkStorm, if it occurred, would have the following effects: The Central Valley experiences hypothetical flooding 300 miles long and 20 or more miles wide.

Geology of the Grand Teton area

Early in Cambrian time a shallow seaway, called the Cordilleran trough, extended from southern California northeastward across Nevada into Utah and Idaho. The vast gently rolling plain on Precambrian rocks to the east was drained by sluggish westward-flowing rivers that carried sand and mud into the sea. The site of the Teton Range was part of this plain. Slow subsidence of the land caused the sea to spread gradually eastward during Middle Cambrian time flooding the Precambrian plain. Sand accumulated along the beaches just as it does today. As the sea moved still farther east, mud was deposited on the now-submerged beach sand.

Hurricane Jimena (2009)

Hurricane JimenaJimena
The downtown area of Santa Rosalía was severely damaged with flash floods. Hurricane-force winds battered the area for hours before diminishing to 45 mph the next day. Water supplies ran low and two bridges were washed out. In a nearby canyon, floodwaters washed out many cars and livestock. In Cabo San Lucas, Jimena produced little damage. However, the entire town of Punta Chivato were flooded and damaged, with some being destroyed. In addition, 75% of homes were damaged in Puerto San Carlos, and power was lost in many areas including Comondú and Loreto.

Cascade Volcanoes

Cascade Volcanic ArcCascadeCascade Arc
When Cascade volcanoes do erupt, pyroclastic flows, lava flows, and landslides can devastate areas more than 10 mi away; and huge mudflows of volcanic ash and debris, called lahars, can inundate valleys more than 50 mi downstream. Falling ash from explosive eruptions can disrupt human activities hundreds of miles downwind, and drifting clouds of fine ash can cause severe damage to jet aircraft even thousands of miles away. All of the known historical eruptions have occurred in Washington, Oregon and in Northern California. The two most recent were Lassen Peak in 1914 to 1921 and a major eruption of Mount St. Helens in 1980. Minor eruptions of Mount St.

Geography of Malaysia

Seismic activity of Malaysiageography
However, the country's tropical climate opens the country to the risk of flooding, landslides and prolonged droughts. With 189 water basins and an average rainfall of over 2000-4000 mm per year, Malaysia is prone to riverine, muddy floods that range from hours-long flash floods, to prolonged flooding on flat, low-lying land along major tributaries and main stems. There have been 15 instances of major flooding in Malaysia since 1926. Flooding has been a major concern in recent decades due to rapid development in river catchment areas that has led to increased surface and river runoffs, increased sediment buildup in rivers, and a higher risk of overflowing rivers.

mudslidemudslidesmud flow
A statutory definition of "flood-related mudslide" appears in the United States' National Flood Insurance Act of 1968, as amended, codified at 42 USC Sections 4001 and following. Heavy rainfall, snowmelt, or high levels of ground water flowing through cracked bedrock may trigger a movement of soil or sediments. Floods and debris flows may also occur when strong rains on hill or mountain slopes cause extensive erosion and/or what is known as "channel scour". The 2006 Sidoarjo mud flow may have been caused by rogue drilling. Some broad mudflows are rather viscous and therefore slow; others begin very quickly and continue like an avalanche.

Among the dead was Odissi dancer Protima Bedi. On July 16, 2003, about 40 people were killed in flash floods caused by a cloudburst at Shilagarh in Gursa area of Kullu district, Himachal Pradesh. On July 6, 2004, at least 17 people were killed and 28 injured when three vehicles were swept into the Alaknanda River by heavy landslides triggered by a cloudburst that left nearly 5,000 pilgrims stranded near Badrinath shrine area in Chamoli district, Uttarakhand.
