Well...there is a sunken freighter from World War Two that still sits on the bottom of the Thames River in England with its cargo of eight thousand tons of World War Two munitions. Artillery shells, grenades, depth charges, etc.
If its cargo were to explode...a big mushroom cloud would rise out of the Thames river, and a big tsunami would go up the Thames, and flood much of London!
So...Londoners....get ready to tread water!

The only one I'm aware of is the SS Richard Montgomery and that's
near Southend which is over 40 miles from London.

According to a survey conducted in 2000, by the United Kingdom Maritime and Coastguard Agency,[5] the wreck still held munitions containing approximately 1,400 tonnes (1,500 short tons) of TNT high explosive.[5] These comprise the following items of ordnance:
286 × 2,000 lb (910 kg) high explosive bombs
4,439 × 1,000 lb (450 kg) bombs of various types
1,925 × 500 lb (230 kg) bombs
2,815 fragmentation bombs and bomb clusters
Various explosive booster charges
Various smoke bombs, including white phosphorus bombs
Various pyrotechnic signals

According to a BBC news report in 1970,[15] it was determined that if the wreck of Richard Montgomery exploded, it would throw a 1,000-foot-wide (300 m) column of water and debris nearly 10,000 feet (3,000 m) into the air and generate a wave 16 feet (5 m) high. Almost every window in Sheerness (pop. circa 20,000) would be broken and buildings would be damaged by the blast. However, news reports in May 2012 (including one by BBC Kent) stated that the wave could be about 4 feet (1 m) high, which although lower than previous estimates would be enough to cause flooding in some coastal settlements.
I would suspect the Thames barrier would protect London from flooding.

The Thames Barrier is a movable barrier system that is designed to prevent the floodplain of most of Greater London from being flooded by exceptionally high tides and storm surges moving up from the North Sea.

Thats the one Im talking about. I was talking off of the top of my head. Couldnt think of the ship's name. Should hav e remember because it has the same name as a rival high school to the one I went to. The high school was named after a ball player. Dont know if they are named after the same Richard Montgomery.
Wiki and other articles say it would flood London, And if it went off then there might not be enough warning to shut the Thames Barrier.
From that inventory of the cargo it looks to have about 4 to 5 thousand tons of explosive cargo. But only half of that weight (at most) would be actual chemical explosive. But thats still easily a one to two thousand tons of TNT. Or about one tenth of Hiroshima. That would be ... a lot of boom... if it actually went off all at once.
