The 2008 Sichuan earthquake, also known as the First Great Sichuan earthquake or Wenchuan earthquake, occurred at 14:28:01 China Standard Time on May 12, 2008. Measuring at 8.0 Ms the earthquake's epicenter was located 80 kilometres (50 mi) west-northwest of Chengdu, the provincial capital, with a focal depth of 19 km (12 mi). Over 69,000 people lost their lives in the quake, including 68,636 in Sichuan province. 374,176 were reported injured, with 18,222 listed as missing as of July 2008. It was the deadliest earthquake to hit China since the 1976 Tangshan earthquake.
In the early hours of August 8, 2010, a huge mudslide struck the county town of Zhouqu in Gansu province, northwest China. The disaster left 1,765 people dead or missing, in addition to destroying buildings and roads. This is the most serious mountain torrent debris flow disaster since the founding of new china.
A 7.0-magnitude earthquake hit Jiuzhaigou county in Southwest China's Sichuan province at 9:19 pm China Standard Time on August 8, 2017, at a depth of 20 kilometers, according to the China Earthquake Networks Center. As of August 14 twenty-five people died and 525 people were injured, lost six, affected 176492 people (including visitors) and 73671 houses were damaged.
In May 2015, India was struck by a severe heat wave. As of 3 June 2015, it has caused the deaths of at least 2,500 people in multiple regions. The heat wave occurred during the Indian dry season, which typically lasts from March to July with peak temperatures in April and May. Although it typically remains hot until late October, Indian monsoons often provide some respite from the heat. The South Indian states of Andhra Pradesh and the neighbouring Telangana, where more than 1,735 and 585 people died respectively, were the areas most affected by the heat wave. Other casualties were from the eastern states of West Bengal and Odisha. The high demand for electricity to power air conditioning led to power outages in some cities. The 2015 heat wave has had the highest recorded temperatures since 1995. In May 2016, a new record was set in Phalodi. According to the Indian Meteorological Department (IMD), a heat wave is qualified when air temperatures of at least 40 °C (104 °F) in the plains or greater than 30 °C (86 °F) in the hilly regions. For the IMD classification of heat waves, temperatures greater than 46 °C (114.8 °F) are considered and classified as severe heat waves.
The Kubuqi Desert is located in Inner Mongolia, on the southern bank of the Yellow River in Erdos, and is the seventh largest desert in China with a total area of 16.8 thousand km2. The Kubuqi desert has implemented many key projects for ecological environment construction, including the construction of desert-crossing highway and the straw slope protection technology to lock the flow sand, and has achieved harmony between roads and ecological governance. The dynamic change in desertification in Kubuqi Desert can be observed in RS images taken across different periods. Through the detailed analysis and interpretation of the sand industry model, a set of sustainable and replicable desertification harnessing and economic coordinated development models are provided.
Da Hinggan Mountains, Heilongjiang, China, has occurred many forest-fires, because of the vast forest area and complex natural conditions, in the past fifty years. The lives and property of the people and the loss of the country's forest resources are heavy. These fires have caused very serious economic property losses and casualties, and produced a large amount of forest damage area. For example, on May 6, 1987, several forest farms in Da Hinggan Mountains, Heilongjiang Province, started to fire at the same time, causing the most serious forest fire since the founding of new China, shocked at home and abroad. The direct economic losses amounted to more than 500 million yuan.
The Indian Ocean tsunami, also known as the south Asian tsunami, occurred on December 26, 2004.Located in the andaman sea. The epicenter was on the ocean floor north of Sumatra, Indonesia. The local seismological bureau measured a magnitude of 6.8 on the Richter scale, while Hong Kong, mainland China and the United States measured a magnitude of 8.5 to 8.7 on the Richter scale. Subsequently, the Hong Kong observatory and the us national earthquake information center revised the magnitude to 8.9 and 9.0 respectively, and the moment magnitude to 9.0.The moment magnitude reached 9.3. Since the earthquake in Chile in 1960 and the 1964 good Friday Alaskan earthquake to the strongest earthquake, but scale since 1900 in the third big earthquake, a tsunami as high as more than 10 meters, spreading as far as the gulf of Oman, east coast of somalia in Africa, and countries such as Mauritius, reunion, cause huge casualties and property losses.
A heat wave is a period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is usually measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area.
