Perhaps you were thinking of something similar, like:
* Meizoseismic: This refers to the epicenter of an earthquake, the point on the Earth's surface directly above the focus where the earthquake originated.
* Macro-seismic: This describes an earthquake that is large enough to be felt by humans and potentially cause damage.
* Seismic: This refers to earthquakes or the vibrations within the Earth that cause them.
If you could provide more context or information about where you encountered the term "malloseismic," I might be able to give you a more accurate answer.
