Here are a few options for the description of the WordPress post tag “芮氏規模” (Ritcher Scale) in Traditional Chinese, varying in their focus and detail:

**Option 1: Concise and Informative**

* **Description:** 用於衡量地震強度的尺度，數值越高，地震威力越大。 (Yòng yú héngliáng dìzhèn qiángdù de chǐdù, shùzhí yuè gāo, dìzhèn wēnlì yuè dà. – Used to measure the intensity of earthquakes; the higher the number, the greater the power of the earthquake.)

**Option 2: Slightly More Detailed**

* **Description:** 芮氏規模，又稱地震規模，是衡量地震震級的常用標準。 它基於地震釋放能量的對數，數字越大，代表地震釋放的能量越多，破壞力也越大。 (Ruì shì guīmó, yòu chēng dìzhèn guīmó, shì héngliáng dìzhèn zhènjí de chángyòng biāozhǔn. Tā jīyú dìzhèn shìfàng néngliàng de duìshù, shùzì yuè dà, dàibiǎo dìzhèn shìfàng de néngliàng yuè duō, pòhuàilì yě yuè dà. – The Richter scale, also known as earthquake magnitude, is a commonly used standard for measuring the magnitude of earthquakes. It’s based on the logarithm of the energy released by an earthquake. The larger the number, the more energy the earthquake releases, and the more destructive it is.)

**Option 3: Focused on Usage in the Blog**

* **Description:** 本標籤下的文章將探討與芮氏規模相關的議題，例如地震的測量方法、歷史上的大地震、以及地震預警和減災措施。 (Běn biāojiān xià de wénzhāng jiāng tàntǎo yǔ ruì shì guīmó xiāngguān de yìtí, rúlì rì dìzhèn de cèliáng fāngfǎ, lìshǐ shàng de dà dìzhèn, yǐjí dìzhèn yùjǐng hé jiǎn zāi cuòshī. – Articles under this tag will explore issues related to the Richter scale, such as methods for measuring earthquakes, historical major earthquakes, and earthquake early warning and disaster reduction measures.)

**Option 4: Simple & Broad**

* **Description:** 關於芮氏規模的所有文章 (Guānyú ruì shì guīmó de suǒyǒu wénzhāng – All articles about the Richter scale.)

**Key things to consider when choosing:**

* **Target Audience:** Are your readers experts or general readers? Option 2 is suitable for a slightly more knowledgeable audience.
* **Blog Content:** What kind of articles do you write about? Option 3 would be preferable if you frequently write about earthquakes, disaster measures, etc.
* **Brevity:** WordPress tag descriptions can be short. Option 1 or 4 are great choices if you want to keep it simple.

I recommend choosing the description that best reflects the current content and future direction of the blog. Good luck!
