One connection between earthquakes and volcanoes is that they all have to do with Plate Tectionics
and they destroy things
Volcanos burn
The Ring of Fire, which stretches around the rim of the Pacific Ocean.
Volcanoes and earthquakes are usually found along plate boundaries because the constant movement allows for lava to flow through easier, and causes release in tension from an earthquake.
Gravitational attraction
There is no relationship between tornadoes and earthquakes.
Volcanos burn

volcanos and earthquakes
Yes. Earthquakes at subduction zones can trigger tsunamis.
earthquakes can cause tsunamis, landslides, flooding, and volcanos
Volcanos and Earthquakes are not weather, neither are Tidal waves as they result from earthquakes or volcanos, however Winds (tornados) and Percipitation (Storms and sheet ice for example) are
around plate boundries.
A small earthquake
yes
seismometers and seismographs
In terms of human deaths accountable to each, earthquakes are way ahead.
