How do you recurse directories, unzip, and move everything up?

Say I have the following directory tree

.
├── a1
│   └── sub1
│       └── a1.zip
└── a2
    └── sub2
        └── a2.zip

The current directory contains a1 and a2 directories. I want to recursively search, locate and extract all zip files, and move everything up to a1 and a2 respectively. The goal state is:

.
├── a1
│   ├── file1
│   └── file2
└── a2
    ├── file1
    └── file2

Where the files came from the zip. How do I accomplish that? What tools should I use in Terminal for that?

EDIT

To be more specific, I mention the recursion since we don't know how many subdirectories there are. It could be:

.
├── a1
│   └── sub1
│       └── sub...
│                └── a1.zip
│                └── text1.txt
└── a2
    └── sub2
        └── sub...
                 └── a2.zip
                 └── text2.txt

Goal:

.
├── a1
│   ├── file1_unzipped
│   └── text1.txt
└── a2
    ├── file1_unzipped
    └── text2.txt

1. Unzip all `.zip` archives

find . -type f -name "*.zip" -exec unzip {} +

Explanations

find . – search current directory for
-type f – files
-name "*.zip" – whose name match *.zip (so ends in .zip),
-exec unzip {} + – make one long list of all matches and and run unzip on it

2. Move all files from lower levels to one level under the current

for i in */; do find "$i" -type f -exec mv {} "$i" \; && rm -r "$i"*/; done

Explanations

for i in */; do …; done – loop over all directories on the current level
find "$i" -type f – search all files in the currently processed directory and below
-exec mv {} "$i" \; – move them to the currently processed directory
&& do the following only if the previous command finished successfully
rm -r "$i"*/ – remove every subdirectory in the currently processed directory
