− | [[ | + | In this comic strip, [[Science Girl]] is presenting her project on geology to her class mates, and is explaining some of the non-earthquake signals that {{w|seismometers}} detect. She describes [https://phys.org/news/2011-01-seismometer-noise-south-atlantic-storms.html a mysterious signal that repeats with a 26-second period]. |
+ | Scientists have exploited this signal to [https://www.researchgate.net/publication/320126150_Assessing_the_short-term_clock_drift_of_early_broadband_stations_with_burst_events_of_the_26_s_persistent_and_localized_microseism correct for clock drift] in historic seismic records. | ||
− | + | [[Science Girl]] initially provides a plausible explanation (some kind of natural wave pattern on the coastline of the {{w|Gulf of Guinea}}). | |
+ | However, she quickly takes a turn for the dramatic when she claims that it might be a giant, murdered by seismologists, whose heart still beats. This is a reference to Edgar Allan Poe's short story ''{{w|The Tell-Tale Heart}}'', in which the main character murders a man and hides his corpse beneath the floorboards, and then hears (or believes he hears) his victim's heart continuing to beat; the noise eventually drives him to confess his guilt to visiting police officers. (The narrator of ''The Tell-Tale Heart'' never uses that phrase in the story; he calls it a ''hideous'' heart.) "The Tell-Tale Heart" was previously referenced in [[740: The Tell-Tale Beat]]. | ||
− | The title text gives an alternate explanation for the seismic activity: [https://academic.oup.com/gji/article/194/1/362/2006108 volcanic activity], but | + | Normal human hearts beat much more rapidly than once every 26 seconds, but [https://www.answers.com/Q/What_animal_has_slowest_heart_rate large animals and hibernating animals] may have much slower heart rates (which would include a giant at the bottom of the ocean). |

+ | The title text gives an alternate explanation for the seismic activity: [https://academic.oup.com/gji/article/194/1/362/2006108 volcanic activity], but Science Girl continues to believe in the giant story. In the last panel she references the common science meme that further research is needed, which has been mentioned several times in previous strips, including [[2268: Further Research is Needed]]. | ||
A seismometer is a device for measuring vibrations in the earth's crust, and one is likely in the collection of Cueball from [[2060: Hygrometer]]. | A seismometer is a device for measuring vibrations in the earth's crust, and one is likely in the collection of Cueball from [[2060: Hygrometer]]. | ||

− | : | + | :Science Girl: When everything is still, seismometers pick up faint tremors we call seismic noise. |
− | : | + | :Science Girl: Most of it is from ocean waves, cars, etc. But there's also a mysterious 26-second pulse. |
− | :[ | + | :[Close up on Science Girl, pointing to a map of the world. Africa is in view, and a star is drawn within the country of Ghana.] |
+ | :Science Girl: We've triangulated the source to somewhere in the Gulf of Guinea. | ||
+ | :Science Girl: It comes and goes with the seasons, but it's been there since at least the 1980s. It's so regular we use it to sync up seismometers. | ||

− | : | + | :Science Girl: Not sure. The most popular theory is that storm-driven waves set up some kind of resonance with the coast. |
− | :[ | + | :[Science Girl has leaned her stick on the board's tray. She has raised her clenched fists.] |
− | : | + | :Science Girl: Another theory is that long ago, seismologists murdered a giant and buried the body at sea. |
− | : | + | :Science Girl: Now we are haunted by the beating of its telltale heart! |
− | : | + | :Science Girl: Could be either. |
− | : | + | :Science Girl: Further research is needed. |
