During the just concluded first half of the South West Monsoon 2020, India received 453.3 mm rainfall, just 1.1 mm above the normal rainfall of 452.2 mm during the period. The Surplus of  18% rainfall that India received in June 2020 has thus been wiped out by the 9.9% deficit in July rainfall. Normal rainfall in July 2020 is 285.3 mm, while actual rainfall was 257.1 mm. IMD does not provide monthly figures of rainfall for different states, sub divisions and river basins, which it should along with comparison with respect to normal rainfall and rainfall last year.

To get July 2020 rainfall, we will need to use the figures given in this article along with the figures of June 2020 rainfall (see: https://sandrp.in/2020/06/30/district-wise-rainfall-in-india-in-june-2020/). The district wise figures of June-July 2020 rainfall can be seen in this PDF file from IMD: IMD DISTRICT WISE RAINFALL FROM JUNE 1 TO JULY 31 2020.

Landslide dam threat in Zanskar Valley to continue for more weeks: Update 2

In the most significant event so far on the issue of landslide blockage of Phutkal River in Zanskar Valley in Kargil District in Kashmir, the National Crisis Management Committee[1] (NCMC) chaired by the Union Cabinet Secretary Shri Ajit Seth met[2] on Feb 20, 2015 and approved the Action Plan whose implementation will begin within next 15 days and is to be completed by end of March. This decision is based on assumption that the snowmelt will cause landslide dam threatening situation only in April.

The landslide dam between Shaday Sumdo and Mar Shun in the Zanskar subdivision of Kargil district has created about 14 km long lake, whose size is increasing with every passing day. Life and properties of around 4000 people are at risk due to the possible flashfloods when the landslide dam breaches.

Landslide Dam blocks Zanskar River tributary, threatens Valley

The picturesque Zanskar Valley in Jammu and Kashmir State in Northern India is under threat as one of the tributaries of the Zanskar River has been blocked by a massive 200 ft high landslide dam (equal to height of a 20 storey building). The landslide dam between Shaday Sumdo and MarShun in the Zanskar subdivision of Kargil district has created about 8 km long lake, whose size is increasing with every passing day. The landslide dam is made of mostly fine grained debris & blocks 97% of the flow of around 50 cusecs flow at this period as per records. While the lake is frozen right now, the threat of its breach looms as soon as the melting season starts. The landslide dam was reportedly created on Dec 31, 2014, when a whole side of mountain soil had landed on the Phuktal River. The landslide lake has been accumulating water for over a month now.
