Idk. You can always just leave out details to make things simpler. I could rewrite your version of the abstract to "Scientist find magma under volcanoes." Much simpler! Leaves out a lot from yours, but so did yours leave out a lot from theirs. I think in this case it is important to consider the audience one is writing to. And the abstract is written to other geologist. They want to know what kind of evidence they have (purely computational? new field measurements? what kind of modality?) While for me this sentence[1] is hard to penetrate jargon, presumably for the intended audience it is packed full of information. Same as the sentence "we persist the setting in a local sqlite database using sqlalchemy ORM" means a lot more to some dev like me than "we save the setting". You can simplify it of course, but while you make it easier to understand to a lay audience it becomes less specific to the intended and specialist audience. 1: "seismic imaging of subvolcanic magmatic systems along the Cascade Range arc from systematically modelling the three-dimensional scattered wavefield of teleseismic body waves"
