Once in Route 128 all you need to do is head underwater and navigate until you find a cave entrance, which holds the Submarine Explorer 1 which Team MagmaR / Team AquaS stole from Captain Stern in Slateport City. Surface from here to reach the Seafloor Cavern.
Also this is the only place to find wild Luvdisc to collect Heart Scales if you need to use the Move relearner in Fallarbor Town. If you wish, head to the east exit to reach Ever Grande City, the place where the Elite Four is. Though you cannot climb the waterfall, you can use the Super Rod to find a wild Wailord, which you will need to catch for the Sealed Chamber unless if you already caught it's pre-evolution.

Before entering, make sure that other than having Dive and Surf, to also have Strength and Rock Smash since there are rocks and boulders here. After heading through the entrance carefully move the boulders to head through and deal with the two grunts. Regardless of which door you use they will lead you to a four door maze filled with rocks and stones. By carefully moving them out of the way you should reach the upper left door which is the correct door.
The next part contains a jet water stream and the trick is to reach for the upper left door without going into the island door which takes you back to the entrance. Followed by that is a room filled with boulders. Use strength and you will face the same Team Magma/Aqua Administrators from the Weather Institute, CourtneyR/ShellyS.
After defeating the Administrator, head up and solve another boulder puzzle to head through the door there.
How to Solve the boulder puzzle
To solve the boulder puzzle follow these steps:
1.Push boulders 1 and 3 up.
2.Push boulber 2 to the left.
3.Push boulder 7 forward.
4.Push boulder 6 left.
5.Push boulder 10 up.
6.Push boulder 8 to the right.
7.Push boulder 11 forward.
8.Push boulder 7 left.
Remember if you do it wrong just leave the room and everything will have reset.
You have now made it to the final room so head on down and collect TM26 (Earthquake) along the way. Once you see the remains of GroudonR/KyogreS, then MaxieR/ArchieS you decides to eliminate you to see their dream come true.
After the battle MaxieR/ArchieS are surprised by your skill but know it is pointless as they use their stolen orb to awaken GroudonR/KyogreS. However the awakened Pokémon only flees which the team leader is surprised with. Just as MaxieR/ArchieS is surprised to learn the weather change is more serious than expected, ArchieR/MaxieS arrive with their team and criticize him for their foolish actions.
You will then be taken outside to see the changed weather of extreme heatR/downpourS just as MaxieR/ArchieS admits their mistake. Once the two team leaders leave, Steven Stone arrives and connects the source of this severe weather condition to Sootopolis City before leaving. Head either from south on Route 124, or west on Route 127 to reach Route 126 where Sootopolis is located.
