A seismograph
The amount of structural and geological damage done by an earthquake in a specific location determines an earthquake's intensity on the Mercalli scale.
If you are using it outdoors for weather measurement, then a location sheltered from the wind is best. If you are using it indoors to monitor laboratory conditions, then a location which is free of drafts is best. That is, avoid placing it near air ducts. The general rule for a barometer is to place it in a location with a low amount of air circulation, so that you can measure the static pressure. Also keep in mind that you want to be able to read the instrument.
Three seismic stations are needed to find the epicenter of an earthquake because all three radial circles made by the stations will only meet at one point. (example: if you only had to circles they would meet at two different points)At least 3
An object's absolute location is its objective location, which technically doesn't exist. Relative location is the location of one object in relation to another object.
It is an ancient weather instrument called a rain gauge. A funnel is inserted into a tube. A measurement of 1/10 inch in the rain gauge is actually 1 inch of rain. It can measure as little as .01 inches of rain.
A seismogram traces the earthquakes motion that is created by the seismograph and the seismograph records vibrations in the ground and determines the location and strength of an earthquake.

since latitude is the distance from the equator the lattitude determines how warm or cold it is
Whatever Instrument that it turns out to be, my issue is; how do we get to confirm its measurements?
