Delhi records high of 34.8 deg C; AQI satisfactory
Last Updated: New Delhi, Aug 6 (PTI) Delhi on Wednesday recorded a maximum temperature of 34.8 degrees Celsius, 1.4 notches below the seasonal average, according to the India Meteorological Department (IMD). The minimum temperature was recorded at 26.1 degrees Celsius, 0.8 degree below the normal, the Met office said. The relative humidity at 8.30 am and 5.30 pm was 80 per cent and 70 per cent, respectively, it said. The IMD has forecast generally cloudy sky with light rain or drizzle for Thursday, with the maximum and minimum temperatures expected to settle around 35 and 25 degrees Celsius, respectively. The air quality was recorded in the 'satisfactory' category, with an Air Quality Index (AQI) reading of 91 at 4 pm on Wednesday, Central Pollution Control Board (CPCB) data showed. According to CPCB, an AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.

Afghanistan earthquake: Two tremors strike region within hours; no damage reported so far
Representative Image (ANI image) An earthquake of 4.4 magnitude struck Afghanistan on Wednesday, according to the National Center for Seismology (NCS). The quake occurred at 2:24 pm IST, at a depth of 155 kilometers. The epicenter was located at latitude 36.51°N and longitude 70.70°E within the Afghan territory. This was the second quake recorded today, as seismic activity continues to affect the region. Earlier, a magnitude 4.2 earthquake struck at 12:19 pm IST. It occurred at a depth of 47 kilometers, with the epicenter located at latitude 36.54°N and longitude 71.52°E. This is the latest in a series of earthquakes to hit the region in recent days. On August 2, a stronger earthquake measuring 5.5 on the Richter scale struck Afghanistan at a depth of 87 kilometers. Prior to that, on July 29, a 4.8-magnitude earthquake was recorded at a shallow depth of just 10 kilometers. Shallow earthquakes are more dangerous than deep earthquakes. This is so because the seismic waves from shallow earthquakes have a shorter distance to travel to the surface, resulting in stronger ground shaking causing more damage to structures and greater casualties. According to the Red Cross, Afghanistan lies on several fault lines between the Indian and Eurasian tectonic plates, particularly in the Hindu Kush mountain region, making it one of the most earthquake-prone areas in the world. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Villas For Sale in Dubai Might Surprise You Dubai villas | search ads Get Deals Undo The United Nations Office for the Coordination of Humanitarian Affairs (UNOCHA), Afghanistan warn that frequent quakes continue to pose a serious threat to communities in the country, which are already vulnerable due to decades of conflict and underdevelopment. The organization also noted that the country is highly vulnerable to natural disasters, including seasonal flooding, landslides and earthquakes.

Land features enable flash floods in Himalayas: IIT Gandhinagar study
New Delhi, Aug 6 (PTI) Flash floods in the Himalayas are primarily influenced by the region's land features, while those occurring along the west coast and in central India are driven by factors that affect water flow, a map of hotspots across the country developed by researchers at the Indian Institute of Technology Gandhinagar shows. Three-fourths of flash floods occurring across the country are triggered due to extreme rainfall and moist conditions of the ground caused by recent, prolonged rains, the study published in the journal 'npj Natural Hazards' found. The remaining one-fourth is solely driven by extreme rainfall, it said. The extreme weather event is highly local, in terms of area impacted, and spans a short duration between when rainfall starts and when flooding peaks, which is usually under six hours, according to the India Meteorological Department (IMD). A key finding of the hotspot analysis, the team said, was that extreme rainfall is becoming more common and intense in several basins not prone to flash floods, 'highlighting that the warming climate can lead to newer flash flood hotspots in the future". The map, described in the study, also identifies the risk emerging in sub-basins that are currently less vulnerable to flash floods. 'Flash flood hotspots are mainly centred in the Himalayas, West Coast, and Central India, with geomorphological factors driving flash floods in the Himalayas and hydrological factors (flashiness) in the West Coast and Central India," the authors wrote. They added, 'The combination of extreme precipitation and wet antecedent conditions triggers most (nearly 3/4th) flash floods while the remaining (nearly 1/4th) are solely driven by extreme precipitation." The study analysed data of temperatures recorded by the IMD during 1981-2020, and that of flash floods from datasets, including the 'Emergency Events Database' (EM-DAT). The datasets are said to explicitly categorise flash floods, distinguishing them from other flood types and are therefore essential for analysing the occurrence of the events across the Indian sub-continent, the team said. The researchers noted that most flash floods in India result from extreme rainfall that occurs over the 18 hours leading up to when water flow peaks. However, only a fourth of the events are directly a result of extreme rainfall, the team said. This highlights that wet ground conditions and prolonged rainfall play a crucial role in the occurrence of flash floods, the authors said. The land surface features of the Indian Himalayas make the region particularly vulnerable to unusual and extreme weather events, such as cloudbursts, extreme precipitation, flash floods, and avalanches. The risk of these events has been increasing recently, which scientists attribute to human-caused climate change. On Tuesday, a cloudburst in Uttarkhand's Uttarkashi district triggered flash floods that claimed the lives of at least four people, severely impacting around half of the high-altitude villages in Dharali. Approximately 130 individuals have been evacuated to safety as rescue operations continue in the area, according to officials.
