'About two weeks ago' and 'being woken' doesn't give too much of a date and time, but I suggest possible seismic activity? The whole area of the Balearics and the Valencian coastline (and inland where I am) is an 'active' area.
, and even if your Spanish is not too good, you should be able to look down the list of recent tremors and see if anything fits your time and date. (I had a quick look, and can't see anything straight away, but you will know more exactly when it was and where you were) I think you can change the web page to English, but don't expect a good translation.

If the above link doesn't work, search 'terremoto alicante' and you should get this web page offered to you.
