The explosion is a bomb that has been set off by team Galactic. At the time, you are in Canalave library. Prof. Rowan asks you to visit Lake Valor to find out what happened.
When you get there, you will see that the lake is just a basin. There are some galactic dudes there that will battle you and also some magikarp (you can't catch these, course, not that you would want to).
When you get to Azelf's cave you will notice Azelf isn't there. this is because the Galactic dudes took it for something else....
Sorry to leave you on a cliff hanger.
you have to take the game out your ds and run it under cold water this will then let you fish in lake valour

Cyrus is the guy that the people protecting lake valor mention
It's not a city, it's Lake Valor.
After the explosion at Lake Valor in Pokémon games like "Pokémon Diamond," "Pearl," and "Platinum," you can access the lake by using the Surf ability to navigate across the water. First, you need to defeat Team Galactic at the nearby headquarters in Veilstone City. Once you've done that, return to Lake Valor, and you’ll find the waterway clear for you to explore the lake and its surroundings.
i dont know its easy go to lake valor
